      The Science Behind Slots

      Online slots are fun to play and are among the most popular games at online casinos.

      You place your bets and hit the Spin button. The reels spin away and stop at a point in time. You win if you hit a winning combination. Simple, right? Yes, and no.

      The entire process is simple for a player, but there is a huge amount of science involved in creating the entire experience: right from the way a slot looks and feels to the way you are guaranteed a completely random outcome for every spin with the random number generator (RNG) and, even further, the psychological aspect that makes slots so successful.

      On this page we take a look at the science behind online slots and how it all works.

      We will first discuss about the RNG and then move on to the science behind the visual aesthetics.

      The Random Number Generator (RNG)

      Especially because of the remote nature of online casino gambling, one critical requirement is fair gaming. Online casinos fulfill this requirement for online slots by using a random number generator (RNG).

      The random number generator is an algorithm generated by a computer Slots room casino no deposit bonus codes 2021 online casinos use to randomize the results of a spin. It does this by generating a sequence of numbers, each number corresponding to a symbol on the reels, which one cannot predict by any means other than by chance.

      There are typically 2 types of RNGs:

      • Hardware Random Number Generator (HRNG): This type of RNG genuinely generates random numbers.

        They are not even computed values that are obtained from an algorithm that executes repeatedly.

        How does online slot machines work

        They are truly random because you don’t even have a repeated set of numbers or a set algorithm to crack them. That is why they are also called True Random Number Generators (TRNG).

      • Pseudo Random Number Generator (PRNG): This type of RNG generates numbers that only look random. This is what it means: if you know the state of the PRNG you can reproduce the random number sequence generated.

      How the RNG Works

      How the RNG Works: The software sets up the algorithm with a seed value.

      This is only natural because for something to execute repeatedly there has to be a beginning: that is the seed value. The seed value is derived from any one of a number of repetitive actions or operations happening in the computer.

      2. How slots work in online casinos - The principle of operation and winning options

        Many players have visited real online casinos to play for real money slots in Canada. They saw how electromechanical devices work, where keys and levers had activated the spinning of the reels. In fact, the online version of slot machines differs little from authentic copies. However, the list of slots in virtual gaming halls is much more comprehensive, and there are tremendous incentives, which is especially important for online casinos in Canada with no deposit bonus.

        How slots work in online casinos

        What is the actual principle of slots?

        As in the case of a real slot, online versions of slot machines are equipped with a playing field with three or more reels, which spin from 3, and above game symbols on each. Stopping the reels determines the combinations collected and allows you to understand whether the player has won. Unlike land-based slot machines, virtual analogs are equipped with a maximum stock of bonus features, including free spins, expanding symbols, jokers, animated bonus rounds, respins, and much more.

        Online slots work on the basis of a random number generator, which determines the result of the reels spinning. This principle is implemented in all Canadian online casinos with no deposit bonus and guarantees the safety of the gaming process while using licensed software.

        Random number generator – what is it?

        We are talking about special software designed to output a random order of numbers. This system is able to generate thousands of different combinations every second, guaranteeing % randomness of the result of combinations of characters. They depend on the generated numbers that appear at the moment of spinning and are duplicated after the reels stop. To understand this process, take a look here:

        • When you press "Start" on the slot machine, a random number is generated.
        • A particular software module processes the number and determines when the reels of the slot should stop.
        • It stops clearly at the specified moment, after which the combination of characters is counted.
        • The collected combination of game symbols is provided to the player, and the winnings are paid according to the paytable (each slot has its own individual one).

        Symbols of slot machines

        Another component of gaming devices is symbols. They are produced in the theme of the slot and stylized for the chosen genre. The symbolism serves as a decoration of the game reels and brings winnings to the real money players in an online casino with no deposit bonus in Canada.

        Today there are several varieties of game symbols: memorable and straightforward. Regular symbols do not include any functions other than chain joining and payouts. You just need to catch a winning combination of signs and get a small or medium prize. Simple symbols are divided according to the size of the bet multiplier and bring different rewards.

        Special slot machine symbols are designed to increase the player's profit and are designed to make the gameplay more interesting and exciting. With its help, innovative bonus options are introduced, which cannot be activated by collecting simple symbols. The set of unique signs includes:

        • Wild helps to organize chains of symbols, replacing unnecessary signs with suitable images.
        • Scatter is often paid anywhere on the screen when collecting from 2 or more symbols. It can activate free spins rounds.
        • Bonus is used to switch to a bonus game with a high chance of getting a great reward.
        • Mystic Coins are available in certain types of slots, where they allow you to quickly win money when collecting 6 or more coins.

        Active Slot Lines

        The concept of a payline is understood as a particular direction of combinations of symbols formation. The old one-armed bandits were allowed to collect winning combinations only in a straight line, in the center of the reels. Today, active tracks can run in different directions: diagonally, zigzag, or in the form of other shapes. The increase in the number of lines depends on the addition of reels, which today are from 3 to 9.

        Classic slot machines offered to collect chains of symbols on paylines. Today, modern slot machines are equipped with from 9 to , options for managing combinations and even more. In addition, you can set a certain bet amount on each line, which will affect the total amount of money for one spin of the reels. Accordingly, raising the level of paylines significantly increases the risk of losing more money. Therefore, you need to play responsibly and open an account in an online casino only after reaching the age of

        Active Slot Lines

        What do you need to win in slot machines?

        The most important factor that influences the winning in slots is luck. Because the random number generator does not allow you to assemble an algorithm for the action of the reels and the issuance of symbols. To increase your chances of success, you can develop personal betting tactics or use existing ones on the Internet. However, this will only slightly increase the probability of winning if you have enough bankroll to play at least spins. But in order to play correctly, you need to understand the game concepts.

        Row of digital-based slot machines inside a casino in Las Vegas

        A slot machine (American English), fruit machine (British English) or poker machine (Australian English and New Zealand English) is a gambling machine that creates a game of chance for its customers. Slot machines are also known pejoratively as one-armed bandits because of the large mechanical levers affixed to the sides of early mechanical machines and the games' ability to empty players' pockets and wallets as thieves would.[1]

        A slot machine's standard layout features a screen displaying three or more reels that "spin" when the game is activated. Some modern slot machines still include a lever as a skeuomorphic design trait to trigger play. However, the mechanics of early machines have been superseded by random number generators, and most are now operated using buttons and touchscreens.

        Slot machines include one or more currency detectors that validate the form of payment, whether coin, cash, voucher, or token. The machine pays out according to the pattern of symbols displayed when the reels stop "spinning". Slot machines are the most popular gambling method in casinos and constitute about 70% of the average U.S. casino's income.[2]

        Digital technology has resulted in variations in the original slot machine concept. As the player is essentially playing a video game, manufacturers can offer more interactive elements, such as advanced bonus rounds and more varied video graphics.

        Etymology[edit]

        The "slot machine" term derives from the slots on the machine for inserting and retrieving coins.[3] "Fruit machine" comes from the traditional fruit images on the spinning reels such as lemons and cherries.[4]

        History[edit]

        "Liberty Bell" machine, manufactured by Charles Fey.

        Sittman and Pitt of Brooklyn, New York developed a gambling machine in that was a precursor to the modern slot machine. It contained five drums holding a total of 50 card faces and was based on poker. The machine proved extremely popular, and soon many bars in the city had one or more of them. Players would insert a nickel and pull a lever, which would spin the drums and the cards that they held, the player hoping for a good poker hand. There was no direct payout mechanism, so a pair of kings might get the player a free beer, whereas a royal flush could pay out cigars or drinks; the prizes were wholly dependent upon what the establishment would offer. To improve the odds for the house, two cards were typically removed from the deck, the ten of spades and the jack of hearts, doubling the odds against winning a royal flush. The drums could also be rearranged to further reduce a player's chance of winning.

        Because of the vast number of possible wins in the original poker-based game, it proved practically impossible to make a machine capable of awarding an automatic payout for all possible winning combinations. At some time between and ,[5]Charles Fey of San Francisco, California devised a much simpler automatic mechanism[6] with three spinning reels containing a total of five symbols: horseshoes, diamonds, spades, hearts and a Liberty Bell; the bell gave the machine its name. By replacing ten cards with five symbols and using three reels instead of five drums, the complexity of reading a win was considerably reduced, allowing Fey to design an effective automatic payout mechanism. Three bells in a row produced the biggest payoff, ten nickels (50¢). Liberty Bell was a huge success and spawned a thriving mechanical gaming device industry. After a few years, the devices were banned in California, but Fey still could not keep up with the demand for them from elsewhere. The Liberty Bell machine was so popular that it was copied by many slot machine manufacturers. The first of these, also called the "Liberty Bell", was produced by the manufacturer Herbert Mills in By , many "bell" machines had been installed in most cigar stores, saloons, bowling alleys, brothels and barber shops.[7] Early machines, including an Liberty Bell, are now part of the Nevada State Museum's Fey Collection.[8]

        The first Liberty Bell machines produced by Mills used the same symbols on the reels as did Charles Fey's original. Soon afterward, another version was produced with patriotic symbols, such as flags and wreaths, on the wheels. Later, a similar machine called the Operator's Bell was produced that included the option of adding a gum-vending attachment. As the gum offered was fruit-flavored, fruit symbols were placed on the reels: lemons, cherries, oranges and plums. A bell was retained, and a picture of a stick of Bell-Fruit Gum, the origin of the bar symbol, was also present. This set of symbols proved highly popular and was used by other companies that began to make their own slot machines: Caille, Watling, Jennings and Pace.[9]

        A commonly used technique to avoid gambling laws in several states was to award food prizes. For this reason, several gumball and other vending machines were regarded with mistrust by the courts. The two Iowa cases of State v. Ellis[10] and State v. Striggles[11] are both used in criminal law classes to illustrate the concept of reliance upon authority as it relates to the axiomatic ignorantia juris non excusat ("ignorance of the law is no excuse").[12] In these cases, a mint vending machine was declared to be a gambling device because the machine would, by internally manufactured chance, occasionally give the next user several tokens exchangeable for more candy. Despite the display of the result of the next use on the machine, the courts ruled that "[t]he machine appealed to the player's propensity to gamble, and that is [a] vice."[13]

        In , Bally developed the first fully electromechanical slot machine called Money Honey (although earlier machines such as Bally's High Hand draw-poker machine had exhibited the basics of electromechanical construction as early as ). Its electromechanical workings made Money Honey the first slot machine with a bottomless hopper and automatic payout of up to coins without the help of an attendant.[14] The popularity of this machine led to the increasing predominance of electronic games, with the side lever soon becoming vestigial.

        The first video slot machine was developed in in Kearny Mesa, California by the Las Vegas–based Fortune Coin Co. This machine used a modified inch (48&#;cm) Sony Trinitron color receiver for the display and logic boards for all slot-machine functions. The prototype was mounted in a full-size, show-ready slot-machine cabinet. The first production units went on trial at the Las Vegas Hilton Hotel. After some modifications to defeat cheating attempts, the video slot machine was approved by the Nevada State Gaming Commission and eventually found popularity on the Las Vegas Strip and in downtown casinos. Fortune Coin Co. and its video slot-machine technology were purchased by IGT (International Gaming Technology) in [citation needed]

        The first American video slot machine to offer a "second screen" bonus round was Reel ’Em In, developed by WMS Industries in [15] This type of machine had appeared in Australia from at least with the Three Bags Full game.[16] With this type of machine, the display changes to provide a different game in which an additional payout may be awarded.

        Operation[edit]

        RAY's Ruusu and Tuplapotti slot machines in Finland

        Depending on the machine, the player can insert cash or, in "ticket-in, ticket-out" machines, a paper ticket with a barcode, into a designated slot on the machine. The machine is then activated by means of a lever or button (either physical or on a touchscreen), which activates reels that spin and stop to rearrange the symbols. If a player matches a winning combination of symbols, the player earns credits based on the paytable. Symbols vary depending on the theme of the machine. Classic symbols include objects such as fruits, bells, and stylized lucky sevens. Most slot games have a theme, such as a specific aesthetic, location, or character. Symbols and other bonus features of the game are typically aligned with the theme. Some themes are licensed from popular media franchises, including films, television series (including game shows such as Wheel of Fortune), entertainers, and musicians.

        Multi-line slot machines have become more popular since the s. These machines have more than one payline, meaning that visible symbols that are not aligned on the main horizontal may be considered as winning combinations. Traditional three-reel slot machines commonly have one, three, or five paylines while video slot machines may have 9, 15, 25, or as many as different paylines. Most accept variable numbers of credits to play, with 1 to 15 credits per line being typical. The higher the amount bet, the higher the payout will be if the player wins.

        One of the main differences between video slot machines and reel machines is in the way payouts are calculated. With reel machines, the only way to win the maximum jackpot is to play the maximum number of coins (usually three, sometimes four or even five coins per spin). With video machines, the fixed payout values are multiplied by the number of coins per line that is being bet. In other words: on a reel machine, the odds are more favorable if the gambler plays with the maximum number of coins available.[17] However, depending on the structure of the game and its bonus features, some video slots may still include features that improve chances at payouts by making increased wagers.

        "Multi-way" games eschew fixed paylines in favor of allowing symbols to pay anywhere, as long as there is at least one in at least three consecutive reels from left to right. Multi-way games may be configured to allow players to bet by-reel: for example, on a game with a 3x5 pattern (often referred to as a way game), playing one reel allows all three symbols in the first reel to potentially pay, but only the center row pays on the remaining reels (often designated by darkening the unused portions of the reels). Other multi-way games use a 4x5 or 5x5 pattern, where there are up to five symbols in each reel, allowing for up to 1, and 3, ways to win respectively. The Australian manufacturer Aristocrat Leisure brands games featuring this system as "Reel Power", "Xtra Reel Power" and "Super Reel Power" respectively. A variation involves patterns where symbols pay adjacent to one another. Most of these games have a hexagonal reel formation, and much like multi-way games, any patterns not played are darkened out of use.

        Denominations can range from 1 cent ("penny slots") all the way up to $ or more per credit. The latter are typically known as "high limit" machines, and machines configured to allow for such wagers are often located in dedicated areas (which may have a separate team of attendants to cater to the needs of those who play there). The machine automatically calculates the number of credits the player receives in exchange for the cash inserted. Newer machines often allow players to choose from a selection of denominations on a splash screen or menu.

        Terminology[edit]

        A bonus is a special feature of the particular game theme, which is activated when certain symbols appear in a winning combination. Bonuses and the number of bonus features vary depending upon the game. Some bonus rounds are a special session of free spins (the number of which is often based on the winning combination that triggers the bonus), often with a different or modified set of winning combinations as the main game and/or other multipliers or increased frequencies of symbols, or a "hold and re-spin" mechanic in which specific symbols (usually marked with values of credits or other prizes) are collected and locked in place over a finite number of spins. In other bonus rounds, the player is presented with several items on a screen from which to choose. As the player chooses items, a number of credits is revealed and awarded. Some bonuses use a mechanical device, such as a spinning wheel, that works in conjunction with the bonus to display the amount won.

        A candle is a light on top of the slot machine. It flashes to alert the operator that change is needed, hand pay is requested or a potential problem with the machine. It can be lit by the player by pressing the "service" or "help" button.

        Carousel refers to a grouping of slot machines, usually in a circle or oval formation.

        A coin hopper is a container where the coins that are immediately available for payouts are held. The hopper is a mechanical device that rotates coins into the coin tray when a player collects credits/coins (by pressing a "Cash Out" button). When a certain preset coin capacity is reached, a coin diverter automatically redirects, or "drops", excess coins into a "drop bucket" or "drop box". (Unused coin hoppers can still be found even on games that exclusively employ Ticket-In, Ticket-Out technology, as a vestige.)

        The credit meter is a display of the amount of money or number of credits on the machine. On mechanical slot machines, this is usually a seven-segment display, but video slot machines typically use stylized text that suits the game's theme and user interface.

        The drop bucket or drop box is a container located in a slot machine's base where excess coins are diverted from the hopper. Typically, a drop bucket is used for low-denomination slot machines and a drop box is used for high-denomination slot machines. A drop box contains a hinged lid with one or more locks whereas a drop bucket does not contain a lid. The contents of drop buckets and drop boxes are collected and counted by the casino on a scheduled basis.

        EGM is short for "Electronic Gaming Machine".

        Free spins are a common form of bonus, where a series of spins are automatically played at no charge at the player's current wager. Free spins are usually triggered via a scatter of at least three designated symbols (with the number of spins dependent on the number of symbols that land). Some games allow the free spins bonus to "retrigger", which adds additional spins on top of those already awarded. There is no theoretical limit to the number of free spins obtainable. Some games may have other features that can also trigger over the course of free spins.

        A hand pay refers to a payout made by an attendant or at an exchange point ("cage"), rather than by the slot machine itself. A hand pay occurs when the amount of the payout exceeds the maximum amount that was preset by the slot machine's operator. Usually, the maximum amount is set at the level where the operator must begin to deduct taxes. A hand pay could also be necessary as a result of a short pay.

        Hopper fill slip is a document used to record the replenishment of the coin in the coin hopper after it becomes depleted as a result of making payouts to players. The slip indicates the amount of coin placed into the hoppers, as well as the signatures of the employees involved in the transaction, the slot machine number and the location and the date.

        MEAL book (Machine entry authorization log) is a log of the employee's entries into the machine.

        Low-level or slant-top slot machines include a stool so the player may sit down. Stand-up or upright slot machines are played while standing.

        Optimal play is a payback percentage based on a gambler using the optimal strategy in a skill-based slot machine game.

        Payline is a line that crosses through one symbol on each reel, along which a winning combination is evaluated. Classic spinning reel machines usually have up to nine paylines, while video slot machines may have as many as one hundred. Paylines could be of various shapes (horizontal, vertical, oblique, triangular, zigzag, etc.)

        Persistent state refers to passive features on some slot machines, some of which able to trigger bonus payouts or other special features if certain conditions are met over time by players on that machine.[18]

        Roll-up is the process of dramatizing a win by playing sounds while the meters count up to the amount that has been won.

        Short pay refers to a partial payout made by a slot machine, which is less than the amount due to the player. This occurs if the coin hopper has been depleted as a result of making earlier payouts to players. The remaining amount due to the player is either paid as a hand pay or an attendant will come and refill the machine.

        A scatter is a pay combination based on occurrences of a designated symbol landing anywhere on the reels, rather than falling in sequence on the same payline. A scatter pay usually requires a minimum of three symbols to land, and the machine may offer increased prizes or jackpots depending on the number that land. Scatters are frequently used to trigger bonus games, such as free spins (with the number of spins multiplying based on the number of scatter symbols that land). The scatter symbol usually cannot be matched using wilds, and some games may require the scatter symbols to appear on consecutive reels in order to pay. On some multiway games, scatter symbols still pay in unused areas.

        Taste is a reference to the small amount often paid out to keep a player seated and continuously betting. Only rarely will machines fail to pay even the minimum out over the course of several pulls.

        Display screen of a slot machine in tilt mode

        Tilt is a term derived from electromechanical slot machines' "tilt switches", which would make or break a circuit when they were tilted or otherwise tampered with that triggered an alarm. While modern machines no longer have tilt switches, any kind of technical fault (door switch in the wrong state, reel motor failure, out of paper, etc.) is still called a "tilt".

        A theoretical hold worksheet is a document provided by the manufacturer for every slot machine that indicates the theoretical percentage the machine should hold based on the amount paid in. The worksheet also indicates the reel strip settings, number of coins that may be played, the payout schedule, the number of reels and other information descriptive of the particular type of slot machine.

        Volatility or variance refers to the measure of risk associated with playing a slot machine. A low-volatility slot machine has regular but smaller wins, while a high-variance slot machine has fewer but bigger wins.

        Weight count is an American term referring to the total value of coins or tokens removed from a slot machine's drop bucket or drop box for counting by the casino's hard count team through the use of a weigh scale.

        Wild symbols substitute for most other symbols in the game (similarly to a joker card), usually excluding scatter and jackpot symbols (or offering a lower prize on non-natural combinations that include wilds). How jokers behave are dependent on the specific game and whether the player is in a bonus or free games mode. Sometimes wild symbols may only appear on certain reels, or have a chance to "stack" across the entire reel.

        Pay table[edit]

        Main article: Pay table

        Each machine has a table that lists the number of credits the player will receive if the symbols listed on the pay table line up on the pay line of the machine. Some symbols are wild and can represent many, or all, of the other symbols to complete a winning line. Especially on older machines, the pay table is listed on the face of the machine, usually above and below the area containing the wheels. On video slot machines, they are usually contained within a help menu, along with information on other features.

        Technology[edit]

        Reels[edit]

        Historically, all slot machines used revolving mechanical reels to display and determine results. Although the original slot machine used five reels, simpler, and therefore more reliable, three reel machines quickly became the standard.

        A problem with three reel machines is that the number of combinations is only cubic &#; the original slot machine with three physical reels and 10 symbols on each reel had only 103 = 1, possible combinations. This limited the manufacturer's ability to offer large jackpots since even the rarest event had a likelihood of %. The maximum theoretical payout, assuming % return to player would be times the bet, but that would leave no room for other pays, making the machine very high risk, and also quite boring.

        Although the number of symbols eventually increased to about 22, allowing 10, combinations,[19] this still limited jackpot sizes as well as the number of possible outcomes.

        In the s, however, slot machine manufacturers incorporated electronics into their products and programmed them to weight particular symbols. Thus the odds of losing symbols appearing on the payline became disproportionate to their actual frequency on the physical reel. A symbol would only appear once on the reel displayed to the player, but could, in fact, occupy several stops on the multiple reel.

        In , Inge Telnaes received a patent for a device titled, "Electronic Gaming Device Utilizing a Random Number Generator for Selecting the Reel Stop Positions" (US Patent ),[20] which states: "It is important to make a machine that is perceived to present greater chances of payoff than it actually has within the legal limitations that games of chance must operate."[21] The patent was later bought by International Game Technology and has since expired.

        A virtual reel that has virtual stops per reel would allow up to 3 = 16,, final positions. The manufacturer could choose to offer a $1 million jackpot on a $1 bet, confident that it will only happen, over the long term, once every million plays.

        Computerization[edit]

        With microprocessors now ubiquitous, the computers inside modern slot machines allow manufacturers to assign a different probability to every symbol on every reel. To the player, it might appear that a winning symbol was "so close", whereas in fact the probability is much lower.

        In the s in the U.K., machines embodying microprocessors became common. These used a number of features to ensure the payout was controlled within the limits of the gambling legislation. As a coin was inserted into the machine, it could go either directly into the cashbox for the benefit of the owner or into a channel that formed the payout reservoir, with the microprocessor monitoring the number of coins in this channel. The drums themselves were driven by stepper motors, controlled by the processor and with proximity sensors monitoring the position of the drums. A "look-up table" within the software allows the processor to know what symbols were being displayed on the drums to the gambler. This allowed the system to control the level of payout by stopping the drums at positions it had determined. If the payout channel had filled up, the payout became more generous; if nearly empty, the payout became less so (thus giving good control of the odds).

        Video slot machines[edit]

        Video slot machines do not use mechanical reels, but use graphical reels on a computerized display. As there are no mechanical constraints on the design of video slot machines, games often use at least five reels, and may also use non-standard layouts. This greatly expands the number of possibilities: a machine can have 50 or more symbols on a reel, giving odds as high as million to 1 against &#; enough for even the largest jackpot. As there are so many combinations possible with five reels, manufacturers do not need to weight the payout symbols (although some may still do so). Instead, higher paying symbols will typically appear only once or twice on each reel, while more common symbols earning a more frequent payout will appear many times. Video slot machines usually make more extensive use of multimedia, and can feature more elaborate minigames as bonuses. Modern cabinets typically use flat-panel displays, but cabinets using larger curved screens (which can provide a more immersive experience for the player) are not uncommon.[22]

        Video slot machines typically encourage the player to play multiple "lines": rather than simply taking the middle of the three symbols displayed on each reel, a line could go from top left to the bottom right or any other pattern specified by the manufacturer. As each symbol is equally likely, there is no difficulty for the manufacturer in allowing the player to take as many of the possible lines on offer as desire &#; the long-term return to the player will be the same. The difference for the player is that the more lines they play, the more likely they are to get paid on a given spin (because they are betting more).

        To avoid seeming as if the player's money is simply ebbing away (whereas a payout of credits on a single-line machine would be bets and the player would feel they had made a substantial win, on a line machine, it would only be five bets and not seem as significant), manufacturers commonly offer bonus games, which can return many times their bet. The player is encouraged to keep playing to reach the bonus: even if they are losing, the bonus game could allow them to win back their losses.

        Random number generators[edit]

        All modern machines are designed using pseudorandom number generators ("PRNGs"), which are constantly generating a sequence of simulated random numbers, at a rate of hundreds or perhaps thousands per second. As soon as the "Play" button is pressed, the most recent random number is used to determine the result. This means that the result varies depending on exactly when the game is played. A fraction of a second earlier or later and the result would be different.

        It is important that the machine contains a high-quality RNG implementation. Because all PRNGs must eventually repeat their number sequence[23] and, if the period is short or the PRNG is otherwise flawed, an advanced player may be able to "predict" the next result. Having access to the PRNG code and seed values, Ronald Dale Harris, a former slot machine programmer, discovered equations for specific gambling games like Keno that allowed him to predict what the next set of selected numbers would be based on the previous games played.

        Most machines are designed to defeat this by generating numbers even when the machine is not being played so the player cannot tell where in the sequence they are, even if they know how the machine was programmed.

        Payout percentage[edit]

        Slot machines are typically programmed to pay out as winnings 0% to 99% of the money that is wagered by players. This is known as the "theoretical payout percentage" or RTP, "return to player". The minimum theoretical payout percentage varies among jurisdictions and is typically established by law or regulation. For example, the minimum payout in Nevada is 75%, in New Jersey 83%, and in Mississippi 80%. The winning patterns on slot machines &#; the amounts they pay and the frequencies of those payouts &#; are carefully selected to yield a certain fraction of the money paid to the "house" (the operator of the slot machine) while returning the rest to the players during play. Suppose that a certain slot machine costs $1 per spin and has a return to player (RTP) of 95%. It can be calculated that, over a sufficiently long period such as 1,, spins, the machine will return an average of $, to its players, who have inserted $1,, during that time. In this (simplified) example, the slot machine is said to pay out 95%. The operator keeps the remaining $50, Within some EGM development organizations this concept is referred to simply as "par". "Par" also manifests itself to gamblers as promotional techniques: "Our 'Loose Slots' have a 93% payback! Play now!"[citation needed]

        A slot machine's theoretical payout percentage is set at the factory when the software is written. Changing the payout percentage after a slot machine has been placed on the gaming floor requires a physical swap of the software or firmware, which is usually stored on an EPROM but may be loaded onto non-volatile random access memory (NVRAM) or even stored on CD-ROM or DVD, depending on the capabilities of the machine and the applicable regulations. Based on current technology, this is a time-consuming process and as such is done infrequently.[citation needed] In certain jurisdictions, such as New Jersey, the EPROM has a tamper-evidentseal and can only be changed in the presence of Gaming Control Board officials. Other jurisdictions, including Nevada, randomly audit slot machines to ensure that they contain only approved software.

        Historically, many casinos, both online and offline, have been unwilling to publish individual game RTP figures, making it impossible for the player to know whether they are playing a "loose" or a "tight" game. Since the turn of the century, some information regarding these figures has started to come into the public domain either through various casinos releasing them—primarily this applies to online casinos—or through studies by independent gambling authorities.[citation needed]

        The return to player is not the only statistic that is of interest. The probabilities of every payout on the pay table is also critical. For example, consider a hypothetical slot machine with a dozen different values on the pay table. However, the probabilities of getting all the payouts are zero except the largest one. If the payout is 4, times the input amount, and it happens every 4, times on average, the return to player is exactly %, but the game would be dull to play. Also, most people would not win anything, and having entries on the paytable that have a return of zero would be deceptive. As these individual probabilities are closely guarded secrets, it is possible that the advertised machines with high return to player simply increase the probabilities of these jackpots. The casino could legally place machines of a similar style payout and advertise that some machines have % return to player. The added advantage is that these large jackpots increase the excitement of the other players.

        The table of probabilities for a specific machine is called the Probability and Accounting Report or PAR sheet, also PARS commonly understood as Paytable and Reel Strips. Mathematician Michael Shackleford revealed the PARS for one commercial slot machine, an original International Gaming TechnologyRed White and Blue machine. This game, in its original form, is obsolete, so these specific probabilities do not apply. He only published the odds after a fan of his sent him some information provided on a slot machine that was posted on a machine in the Netherlands. The psychology of the machine design is quickly revealed. There are 13 possible payouts ranging from to 2, The payout comes every 8 plays. The payout comes every 33 plays, whereas the payout comes every plays. Most players assume the likelihood increases proportionate to the payout. The one mid-size payout that is designed to give the player a thrill is the payout. It is programmed to occur an average of once every plays. The payout is high enough to create excitement, but not high enough that it makes it likely that the player will take their winnings and abandon the game. More than likely the player began the game with at least 80 times his bet (for instance there are 80 quarters in $20). In contrast the payout occurs only on average of once every 6, plays. The highest payout of 2, occurs only on average of once every 643 = , plays since the machine has 64 virtual stops. The player who continues to feed the machine is likely to have several mid-size payouts, but unlikely to have a large payout. He quits after he is bored or has exhausted his bankroll.[citation needed]

        Despite their confidentiality, occasionally a PAR sheet is posted on a website. They have limited value to the player, because usually a machine will have 8 to 12 different possible programs with varying payouts. In addition, slight variations of each machine (e.g., with double jackpots or five times play) are always being developed. The casino operator can choose which EPROM chip to install in any particular machine to select the payout desired. The result is that there is not really such a thing as a high payback type of machine, since every machine potentially has multiple settings. From October to February , columnist Michael Shackleford obtained PAR sheets for five different nickel machines; four IGT games Austin Powers, Fortune Cookie, Leopard Spots and Wheel of Fortune and one game manufactured by WMS; Reel 'em In. Without revealing the proprietary information, he developed a program that would allow him to determine with usually less than a dozen plays on each machine which EPROM chip was installed. Then he did a survey of over machines in 70 different casinos in Las Vegas. He averaged the data, and assigned an average payback percentage to the machines in each casino. The resultant list was widely publicized for marketing purposes (especially by the Palms casino which had the top ranking).[citation needed]

        One reason that the slot machine is so profitable to a casino is that the player must play the high house edge and high payout wagers along with the low house edge and low payout wagers. In a more traditional wagering game like craps, the player knows that certain wagers have almost a 50/50 chance of winning or losing, but they only pay a limited multiple of the original bet (usually no higher than three times). Other bets have a higher house edge, but the player is rewarded with a bigger win (up to thirty times in craps). The player can choose what kind of wager he wants to make. A slot machine does not afford such an opportunity. Theoretically, the operator could make these probabilities available, or allow the player to choose which one so that the player is free to make a choice. However, no operator has ever enacted this strategy. Different machines have different maximum payouts, but without knowing the odds of getting the jackpot, there is no rational way to differentiate.

        In many markets where central monitoring and control systems are used to link machines for auditing and security purposes, usually in wide area networks of multiple venues and thousands of machines, player return must usually be changed from a central computer rather than at each machine. A range of percentages is set in the game software and selected remotely.

        In , the Nevada Gaming Commission began working with Las Vegas casinos on technology that would allow the casino's management to change the game, the odds, and the payouts remotely. The change cannot be done instantaneously, but only after the selected machine has been idle for at least four minutes. After the change is made, the machine must be locked to new players for four minutes and display an on-screen message informing potential players that a change is being made.[24]

        Linked machines[edit]

        Some varieties of slot machines can be linked together in a setup sometimes known as a "community" game. The most basic form of this setup involves progressive jackpots that are shared between the bank of machines, but may include multiplayer bonuses and other features.[25]

        In some cases multiple machines are linked across multiple casinos. In these cases, the machines may be owned by the manufacturer, who is responsible for paying the jackpot. The casinos lease the machines rather than owning them outright. Casinos in New Jersey, Nevada, and South Dakota now offer multi-state progressive jackpots, which now offer bigger jackpot pools.[26][27]

        Fraud[edit]

        Mechanical slot machines and their coin acceptors were sometimes susceptible to cheating devices and other scams. One historical example involved spinning a coin with a short length of plastic wire. The weight and size of the coin would be accepted by the machine and credits would be granted. However, the spin created by the plastic wire would cause the coin to exit through the reject chute into the payout tray. This particular scam has become obsolete due to improvements in newer slot machines. Another obsolete method of defeating slot machines was to use a light source to confuse the optical sensor used to count coins during payout.[28]

        Modern slot machines are controlled by EPROM computer chips and, in large casinos, coin acceptors have become obsolete in favor of bill acceptors. These machines and their bill acceptors are designed with advanced anti-cheating and anti-counterfeiting measures and are difficult to defraud. Early computerized slot machines were sometimes defrauded through the use of cheating devices, such as the "slider", "monkey paw", "lightwand" and "the tongue". Many of these old cheating devices were made by the late Tommy Glenn Carmichael, a slot machine fraudster who reportedly stole over $5 million.[29] In the modern day, computerized slot machines are fully deterministic and thus outcomes can be sometimes successfully predicted.[30]

        Skill stops[edit]

        Skill stop buttons predated the Bally electromechanical slot machines of the s and s. They appeared on mechanical slot machines manufactured by Mills Novelty Co. as early as the mid s. These machines had modified reel-stop arms, which allowed them to be released from the timing bar, earlier than in a normal play, simply by pressing the buttons on the front of the machine, located between each reel.

        "Skill stop" buttons were added to some slot machines by Zacharias Anthony in the early s. These enabled the player to stop each reel, allowing a degree of "skill" so as to satisfy the New Jersey gaming laws of the day which required that players were able to control the game in some way. The original conversion was applied to approximately 50 late-model Bally slot machines. Because the typical machine stopped the reels automatically in less than 10 seconds, weights were added to the mechanical timers to prolong the automatic stopping of the reels. By the time the New Jersey Alcoholic Beverages Commission (ABC) had approved the conversion for use in New Jersey arcades, the word was out and every other distributor began adding skill stops. The machines were a huge hit on the Jersey Shore and the remaining unconverted Bally machines were destroyed as they had become instantly obsolete.[citation needed]

        Legislation[edit]

        United States[edit]

        In the United States, the public and private availability of slot machines is highly regulated by state governments. Many states have established gaming control boards to regulate the possession and use of slot machines and other form of gaming.

        Nevada is the only state that has no significant restrictions against slot machines both for public and private use. In New Jersey, slot machines are only allowed in hotel casinos operated in Atlantic City. Several states (Indiana, Louisiana and Missouri) allow slot machines (as well as any casino-style gambling) only on licensed riverboats or permanently anchored barges. Since Hurricane Katrina, Mississippi has removed the requirement that casinos on the Gulf Coast operate on barges and now allows them on land along the shoreline. Delaware allows slot machines at three horse tracks; they are regulated by the state lottery commission. In Wisconsin, bars and taverns are allowed to have up to five machines. These machines usually allow a player to either take a payout, or gamble it on a double-or-nothing "side game".

        The territory of Puerto Rico places significant restrictions on slot machine ownership, but the law is widely flouted and slot machines are common in bars and coffeeshops.[31]

        In regards to tribal casinos located on Native American reservations, slot machines played against the house and operating independently from a centralized computer system are classified as "Class III" gaming by the Indian Gaming Regulatory Act (IGRA), and sometimes promoted as "Vegas-style" slot machines.[32] In order to offer Class III gaming, tribes must enter into a compact (agreement) with the state that is approved by the Department of the Interior, which may contain restrictions on the types and quantity of such games. As a workaround, some casinos may operate slot machines as "Class II" games—a category that includes games where players play exclusively against at least one other opponent and not the house, such as bingo or any related games (such as pull-tabs). In these cases, the reels are an entertainment display with a pre-determined outcome based on a centralized game played against other players. Under the IGRA, Class II games are regulated by individual tribes and the National Indian Gaming Commission, and do not require any additional approval if the state already permits tribal gaming.[33][34]

        Some historical race wagering terminals operate in a similar manner, with the machines using slots as an entertainment display for outcomes paid using the parimutuel betting system, based on results of randomly-selected, previously-held horse races (with the player able to view selected details about the race and adjust their picks before playing the credit, or otherwise use an auto-bet system).[35]

        Private ownership[edit]

        See also: United States slot machine ownership regulations by state

        Alaska, Arizona, Arkansas, Kentucky, Maine, Minnesota, Nevada, Ohio, Rhode Island, Texas, Utah, Virginia, and West Virginia place no restrictions on private ownership of slot machines. Conversely, in Connecticut, Hawaii, Nebraska, South Carolina, and Tennessee, private ownership of any slot machine is completely prohibited. The remaining states allow slot machines of a certain age (typically 25–30 years) or slot machines manufactured before a specific date.

        Canada[edit]

        The Government of Canada has minimal involvement in gambling beyond the Canadian Criminal Code. In essence, the term "lottery scheme" used in the code means slot machines, bingo and table games normally associated with a casino. These fall under the jurisdiction of the province or territory without reference to the federal government; in practice, all Canadian provinces operate gaming boards that oversee lotteries, casinos and video lottery terminals under their jurisdiction.

        OLG piloted a classification system for slot machines at the Grand River Raceway developed by University of Waterloo professor Kevin Harrigan, as part of its PlaySmart initiative for responsible gambling. Inspired by nutrition labels on foods, they displayed metrics such as volatility and frequency of payouts.[36] OLG has also deployed electronic gaming machines with pre-determined outcomes based on a bingo or pull-tab game, initially branded as "TapTix", which visually resemble slot machines.[37]

        Australia[edit]

        In Australia "Poker Machines" or "pokies"[38] are officially termed "gaming machines". In Australia, gaming machines are a matter for state governments, so laws vary between states. Gaming machines are found in casinos (approximately one in each major city), pubs and clubs in some states (usually sports, social, or RSL clubs). The first Australian state to legalize this style of gambling was New South Wales, when in they were made legal in all registered clubs in the state. There are suggestions that the proliferation of poker machines has led to increased levels of problem gambling; however, the precise nature of this link is still open to research.[39]

        In the Australian Productivity Commission reported that nearly half Australia's gaming machines were in New South Wales. At the time, 21% of all the gambling machines in the world were operating in Australia and, on a per capita basis, Australia had roughly five times as many gaming machines as the United States. Australia ranks 8th in total number of gaming machines after Japan, U.S.A., Italy, U.K., Spain and Germany. This primarily is because gaming machines have been legal in the state of New South Wales since ; over time, the number of machines has grown to 97, (at December , including the Australian Capital Territory). By way of comparison, the U.S. State of Nevada, which legalised gaming including slots several decades before N.S.W., had , slots operating.[40]

        Revenue from gaming machines in pubs and clubs accounts for more than half of the $4 billion in gambling revenue collected by state governments in fiscal year &#;[citation needed]

        In Queensland, gaming machines in pubs and clubs must provide a return rate of 85%, while machines located in casinos must provide a return rate of 90%.[citation needed] Most other states have similar provisions. In Victoria, gaming machines must provide a minimum return rate of 87% (including jackpot contribution), including machines in Crown Casino. As of December 1, , Victoria banned gaming machines that accepted $ notes; all gaming machines made since comply with this rule. This new law also banned machines with an automatic play option. One exception exists in Crown Casino for any player with a VIP loyalty card: they can still insert $ notes and use an autoplay feature (whereby the machine will automatically play until credit is exhausted or the player intervenes). All gaming machines in Victoria have an information screen accessible to the user by pressing the "i key" button, showing the game rules, paytable, return to player percentage, and the top and bottom five combinations with their odds. These combinations are stated to be played on a minimum bet (usually 1 credit per line, with 1 line or reel played, although some newer machines do not have an option to play 1 line; some machines may only allow maximum lines to be played), excluding feature wins.

        Western Australia has the most restrictive regulations on electronic gaming machines in general, with the Crown Perth casino resort being the only venue allowed to operate them,[41] and banning slot machines with spinning reels entirely. This policy had an extensive political history, reaffirmed by the Royal Commission into Gambling:[42]

        Poker machine playing is a mindless, repetitive and insidious form of gambling which has many undesirable features. It requires no thought, no skill or social contact. The odds are never about winning. Watching people playing the machines over long periods of time, the impressionistic evidence at least is that they are addictive to many people. Historically poker machines have been banned from Western Australia and we consider that, in the public interest, they should stay banned.

        While Western Australian gaming machines are similar to the other states', they do not have spinning reels. Therefore, different animations are used in place of the spinning reels in order to display each game result.

        Nick Xenophon was elected on an independent No Pokies ticket in the South Australian Legislative Council at the South Australian state election on percent, re-elected at the election on percent, and elected to the Australian Senate at the federal election on percent. Independent candidate Andrew Wilkie, an anti-pokies campaigner, was elected to the Australian House of Representatives seat of Denison at the federal election. Wilkie was one of four crossbenchers who supported the GillardLabor government following the hung parliament result. Wilkie immediately began forging ties with Xenophon as soon as it was apparent that he was elected. In exchange for Wilkie's support, the Labor government are attempting to implement precommitment technology for high-bet/high-intensity poker machines, against opposition from the Tony AbbottCoalition and Clubs Australia.

        During the COVID pandemic of , every establishment in the country that facilitated poker machines was shut down, in an attempt to curb the spread of the virus, bringing Australia's usage of poker machines effectively to zero.[43]

        Russia[edit]

        In Russia, "slot clubs" appeared quite late, only in Before , slot machines were only in casinos and small shops, but later slot clubs began appearing all over the country. The most popular and numerous were "Vulcan " and "Taj Mahal". Since when gambling establishments were banned, almost all slot clubs disappeared and are found only in a specially authorized gambling zones.

        United Kingdom[edit]

        Row of old fruit machines in Teignmouth Pier, Devon

        Slot machines are covered by the Gambling Act , which superseded the Gaming Act [44]

        Slot machines in the U.K. are categorised by definitions produced by the Gambling Commission as part of the Gambling Act of

        Machine category Maximum stake (from January ) Maximum prize (from January )
        A Unlimited Unlimited
        B1 £5 £10, or if the game has a progressive jackpot that can be £20,
        B2 £ (in multiples of £10) £
        B3 £2 £
        B3A £1 £
        B4 £2 £
        C £1 £ or £ If jackpot is repeated
        D (various) 10p to £8 £8 cash or £50 non-cash

        Casinos built under the provisions of the Act are allowed to house either up to twenty machines of categories B–D or any number of C–D machines. As defined by the Act, large casinos can have a maximum of one hundred and fifty machines in any combination of categories B–D (subject to a machine-to-table ratio of ); small casinos can have a maximum of eighty machines in any combination of categories B–D (subject to a machine-to-table ratio of ).

        Category A[edit]

        Category A games were defined in preparation for the planned "Super Casinos". Despite a lengthy bidding process with Manchester being chosen as the single planned location, the development was cancelled soon after Gordon Brown became Prime Minister of the United Kingdom. As a result, there are no lawful Category A games in the U.K.

        Category B[edit]

        Category B games are divided into subcategories. The differences between B1, B3 and B4 games are mainly the stake and prizes as defined in the above table. Category B2 games &#; Fixed odds betting terminals (FOBTs) &#; have quite different stake and prize rules: FOBTs are mainly found in licensed betting shops, or bookmakers, usually in the form of electronic roulette.

        The games are based on a random number generator; thus each game's probability of getting the jackpot is independent of any other game: probabilities are all equal. If a pseudorandom number generator is used instead of a truly random one, probabilities are not independent since each number is determined at least in part by the one generated before it.

        Category C[edit]

        Category C games are often referred to as fruit machines, one-armed bandits and AWP (amusement with prize). Fruit machines are commonly found in pubs, clubs, and arcades. Machines commonly have three but can be found with four or five reels, each with 16–24 symbols printed around them. The reels are spun each play, from which the appearance of particular combinations of symbols result in payment of their associated winnings by the machine (or alternatively initiation of a subgame). These games often have many extra features, trails and subgames with opportunities to win money; usually more than can be won from just the payouts on the reel combinations.

        Fruit machines in the U.K. almost universally have the following features, generally selected at random using a pseudorandom number generator:

        • A player (known in the industry as a punter) may be given the opportunity to hold one or more reels before spinning, meaning they will not be spun but instead retain their displayed symbols yet otherwise count normally for that play. This can sometimes increase the chance of winning, especially if two or more reels are held.
        • A player may also be given a number of nudges following a spin (or, in some machines, as a result in a subgame). A nudge is a step rotation of a reel chosen by the player (the machine may not allow all reels to be nudged for a particular play).
        • Cheats can also be made available on the internet or through emailed newsletters to subscribers. These cheats give the player the impression of an advantage, whereas in reality the payout percentage remains exactly the same. The most widely used cheat is known as hold after a nudge and increases the chance that the player will win following an unsuccessful nudge. Machines from the early s did not advertise the concept of hold after a nudge when this feature was first introduced, it became so well known amongst players and widespread amongst new machine releases that it is now well-advertised on the machine during play. This is characterized by messages on the display such as DON'T HOLD ANY or LET 'EM SPIN and is a designed feature of the machine, not a cheat at all. Holding the same pair three times on three consecutive spins also gives a guaranteed win on most machines that offer holds.

        It is known for machines to pay out multiple jackpots, one after the other (this is known as a "repeat") but each jackpot requires a new game to be played so as not to violate the law about the maximum payout on a single play. Typically this involves the player only pressing the Start button at the "repeat" prompt, for which a single credit is taken, regardless of whether this causes the reels to spin or not. Machines are also known to intentionally set aside money, which is later awarded in a series of wins, known as a "streak". The minimum payout percentage is 70%, with pubs often setting the payout at around 78%.

        Japan[edit]

        Further information: Pachinko

        Japanese slot machines, known as pachisuro (パチスロ) or pachislot from the words "pachinko" and "slot machine", are a descendant of the traditional Japanese pachinko game. Slot machines are a fairly new phenomenon and they can be found mostly in pachinko parlors and the adult sections of amusement arcades, known as game centers.

        The machines are regulated with integrated circuits, and have six different levels changing the odds of a The levels provide a rough outcome of between 90% to % (% for skilled players). Japanese slot machines are "beatable". Parlor operators naturally set most machines to simply collect money, but intentionally place a few paying machines on the floor so that there will be at least someone winning,[citation needed] encouraging players on the losing machines to keep gambling, using the psychology of the gambler's fallacy.

        Despite the many varieties of pachislot machines, there are certain rules and regulations put forward by the Security Electronics and Communication Technology Association (保安電子通信技術協会), an affiliate of the National Police Agency. For example, there must be three reels. All reels must be accompanied by buttons which allow players to manually stop them, reels may not spin faster than 80 RPM, and reels must stop within seconds of a button press. In practice, this means that machines cannot let reels slip more than 4 symbols. Other rules include a 15 coin payout cap, a 50 credit cap on machines, a 3 coin maximum bet, and other such regulations.[citation needed]

        Although a 15 coin payout may seem quite low, regulations allow "Big Bonus" (c. – coins) and "Regular Bonus" modes (c. coins) where these 15 coin payouts occur nearly continuously until the bonus mode is finished. While the machine is in bonus mode, the player is entertained with special winning scenes on the LCD display, and energizing music is heard, payout after payout.

        Three other unique features of Pachisuro machines are "stock", "renchan", and tenjō (天井). On many machines, when enough money to afford a bonus is taken in, the bonus is not immediately awarded. Typically the game merely stops making the reels slip off the bonus symbols for a few games. If the player fails to hit the bonus during these "standby games", it is added to the "stock" for later collection. Many current games, after finishing a bonus round, set the probability to release additional stock (gained from earlier players failing to get a bonus last time the machine stopped making the reels slip for a bit) very high for the first few games. As a result, a lucky player may get to play several bonus rounds in a row (a "renchan"), making payouts of 5, or even 10, coins possible. The lure of "stock" waiting in the machine, and the possibility of "renchan" tease the gambler to keep feeding the machine. To tease them further, there is a tenjō (ceiling), a maximum limit on the number of games between "stock" release. For example, if the tenjō is 1,, and the number of games played since the last bonus is 1,, the player is guaranteed to release a bonus within just 10 games.

        Because of the "stock", "renchan", and tenjō systems, it is possible to make money by simply playing machines on which someone has just lost a huge amount of money. This is called being a "hyena". They are easy to recognize, roaming the aisles for a "kamo" ("sucker" in English) to leave his machine.

        In short, the regulations allowing "stock", "renchan", and tenjō transformed the pachisuro from a low-stakes form of entertainment just a few years back to hardcore gambling. Many people may be gambling more than they can afford, and the big payouts also lure unsavory "hyena" types into the gambling halls.

        To address these social issues, a new regulation (Version ) was adopted in which caps the maximum amount of "stock" a machine can hold to around 2,–3, coins' worth of bonus games. Moreover, all pachisuro machines must be re-evaluated for regulation compliance every three years. Version came out in , so that means all those machines with the up to 10, coin payouts will be removed from service by

        Jackpot disputes[edit]

        Electronic slot machines can malfunction. When the displayed amount is smaller than the one it is supposed to be, the error usually goes unnoticed. When it happens the other way, disputes are likely.[45] Below are some notable arguments caused by the owners of the machines saying that the displayed amounts were far larger than the ones patrons should get.

        United States of America[edit]

        Two such cases occurred in casinos in Colorado in , where software errors led to indicated jackpots of $11 million and $42 million.[citation needed] Analysis of machine records by the state Gaming Commission revealed faults, with the true jackpot being substantially smaller.[46] State gaming laws did not require a casino to honour payouts in that case.

        Vietnam[edit]

        On October 25, , while a Vietnamese American man, Ly Sam, was playing a slot machine in the Palazzo Club at the Sheraton Saigon Hotel in Ho Chi Minh City, Vietnam, it displayed that he had hit a jackpot of US$55,,[47] The casino refused to pay, saying it was a machine error, Mr Ly sued the casino.[48] On January 7, , the District 1 People's Court in Ho Chi Minh City decided that the casino had to pay the amount Mr Ly claimed in full, not trusting the error report from an inspection company hired by the casino.[49] Both sides appealed thereafter, and Mr Ly asked for interest while the casino refused to pay him.[50] In January, , the news reported that the case had been settled out of court, and Mr Ly had received an undisclosed sum.[51]

        Problem gambling and slot machines[edit]

        Mills Novelty Co. Horse Head Bonus antique slot machine

        Natasha Dow Schüll, associate professor in New York University's Department of Media, Culture and Communication, uses the term "machine zone" to describe the state of immersion that users of slot machines experience when gambling, where they lose a sense of time, space, bodily awareness, and monetary value.[52]

        Mike Dixon, PhD, professor of psychology at the University of Waterloo,[53] studies the relationship between slot players and machines. In one of Dixon's studies, players were observed experiencing heightened arousal from the sensory stimulus coming from the machines. They "sought to show that these 'losses disguised as wins' (LDWs) would be as arousing as wins, and more arousing than regular losses."[54]

        Psychologists Robert Breen and Marc Zimmerman[55][56] found that players of video slot machines reach a debilitating level of involvement with gambling three times as rapidly as those who play traditional casino games, even if they have engaged in other forms of gambling without problems.

        Eye-tracking research in local bookkeepers' offices in the UK suggested that, in slots games, the reels dominated players' visual attention, and that problem gamblers looked more frequently at amount-won messages than did those without gambling problems.[57]

        The 60 Minutes report "Slot Machines: The Big Gamble"[58] focused on the link between slot machines and gambling addiction.

        The Popularity of Online Slots in Casinos

         

        Slot machines are one of the gaming components that has undergone rapid innovation. Slot machines are among the oldest kinds of gaming, dating back many years. When compared to old slot machines, modern slot machines are a new creation.

        Modern slot machines are adorned in various themes that entice players to invest in them. The majority of casino games are slots. Slot machines are estimated to account for over 70% of all casino games.

        Several variables have influenced the popularity of online slots. Here are a few examples:

        Slot Machines Are Games of Chance

        The outcome of online slot machines is entirely dependent on chance. This implies that you do not need to be familiar with any gaming strategy to participate. This makes the game popular among players who do not want to spend time researching and comprehending gaming methods, as is the case with games like blackjack.

        Increased Payout Ratios

        Slot machines are by far the most lucrative casino games. You can win up to x the amount of your stake. It is everyone&#;s goal to make more and more money, which makes slot machines so appealing.

        Attractive Slot Machine Packaging

        Today&#;s slot machines, which can be found at the top India slots casinos, are designed and developed to express a concept. These topics include entertainment, sports, and movie themes.

        Not only have slot machine operators invested in high-quality graphics, but also in audio effects, which create an immersive experience for the players. This makes the slot machines popular among players because they can relate to the themes.

        Unique gameplay Aspects

        Online slots are significantly easier to implement unique gameplay elements than other casino games. Almost every online new game has something unique to it. It can be a distinct sort of wild symbol, an interesting reel layout, or a multi-level bonus feature. You are always receiving fresh information. Boredom is never an option.

        On the surface, online slots appear to be straightforward. The player sets their wager and then presses the spin button. The reels then spin and come to a stop at a certain point. If the player is fortunate, they will receive a winning combination and win.

        Science and technology have made all of this possible. That is how the game is constructed, as well as the gambler&#;s experience and the outcome. On online slots, there are two key components: The Random Number Generator (RNG) and the Return to Player (RTP) Value.

        Random Number Generator

        Slot machine operations were not always as complex as they are now. Nowadays, all slot machines are controlled by a software program. Using a Random Number Generator, the program assures that the slots&#; outcomes are fair. The Random Number Generator (RNG) is software that ensures that all of the outcomes of a slot machine are random and independent.

        This dramatically boosts players&#; faith in slot machines since they are guaranteed to be fair. The random number generator appears to disprove the gambler&#;s fallacy. The gambler&#;s fallacy is the notion that if the same result is acquired repeatedly, the outcome of a spin will change.

        Return to Player Percentage

        The return to player percentage, abbreviated as RTP, is a guaranteed return of your wager amount that you may anticipate getting in the long term from playing a slot machine. Due to the house edge, the return to player percentage can never be %.

        The house edge is the casino&#;s advantage over the player and is the inverse of the return to player percentage. This indicates that if a slot machine has a 96 percent return to player percentage and you bet $, you should win 96 dollars in the long term.

        This is the most important feature of a slot machine since it decides the winnings. The pay line is the line that directs the payment based on a winning combination.

        Slot machines typically feature pay lines, and if you choose a slot game with 13 pay lines, you have 13 opportunities to win. They can go straight, zigzag, or diagonally over the reels. Any of the pay lines can trigger a reward. The symbols do not have to be next to each other.

        There are several sorts of online slots. Players are advised to become familiar with them to find the ones that best suit their bankrolls.

        Classic Slots

        Classic slots have three reels and are fast-paced. They also lack bonuses and rely on common symbols like diamonds and fruits.

        Video Slots

        Video slotsinclude at least five reels and employ audiovisual effects and high-quality graphics. The technology utilized in video slots is advanced, and it is worth mentioning that the majority of slot games available online fall into this category.

        Progressive Slots

        Progressive slots are known for paying out the most money. The enormous payout can be explained by the fact that the slots are progressive, which means that the jackpot grows with each game played but not won. Every time a player places a bet, money is added to the jackpot.

        Branded Slots

        Branded slots are relatively new to the gaming industry and incorporate themes based on television personalities, movies, and rock bands. Branded slots provide more winning possibilities and enjoyment than most other slots.

        Interactive Slots

        Interactive slots are very popular and have made significant contributions to the evolution of slots. They have multi-reel and multi-pay line formats that set them apart from other slots. By creating their narratives, players may use the features of their current smartphones to enhance their slot experience.

        When it comes to online slots, the site you play on is important. You should choose a licensed and controlled site. This is the only way to achieve equity and safety. By joining an unauthorized online slot casino, you put yourself in danger of fraud and financial loss.

        Online slotsare a popular online casino game. They are enjoyable and well-liked since they are low-risk and simple to grasp. If you want to start playing slots online, you need first to learn about the various varieties and how they function.

      It could be processes that are running, the specific pattern to a mouse click, a specific set of keystrokes, or even the computer’s clock.

      What this means for Slots: Each symbol on a reel has a specific value assigned to it. When you spin the reels the RNG algorithm throws up unique numbers, at the speed of hundreds per second. The set of numbers that are thrown up when the reels stop spinning determine the symbols that appear on your computer screen at that point in time.

      The arrangement of the symbols on the reels, determined by the numbers they are represented by, determine whether you won, and by how much. That is how random the whole exercise is.

If you want to know how to get better chances to win at slots, you need a machine that pays out more than the other ones.

The RTP is not the amount of money you;ll get back when you wager on real money slots and it doesn;t indicate whether you have fewer chances to hit a bonus round or not.

Also, when you play real money slots online, you can check the games themselves. The RTP number is always mentioned somewhere.

      There is another factor to consider: each symbol is weighted uniquely. This means in a game with 24 symbols per reel the chances of a symbol landing on a particular reel are effectively 1 in 24 and completely random.

      Usually lower symbols are more heavily weighted. The probability of you landing a lower weighted symbol is far higher than the probability of landing a more heavily weighted symbol, like a bonus symbol or, to take it to an even higher level of randomness, the probability of landing a set of bonus symbols to trigger a bonus round.

      While the process itself is random, players need to be assured of that fact. That is why every reputable online casino gets its RNG audited by an independent third party that is known for its neutrality. Some of the most popular testing agencies that the online casino industry uses are:

      The Return to Player (RTP) Value

      Another bit of science that plays out when it comes to online slots is the return to player (RTP) value.

      The RTP value tells you how much, over a period of time, a slot pays you back. This value is usually calculated and represented as a percentage value; so a slot with a RTP value of 96% literally means that for every $ you wager the machine will pay you back $96 over a period of time. One thing to remember: this is a theoretical value and a statistical calculation.

      In the above example, the RTP value is the 96%, and the 4% is the house edge.

      So on every $ you wager, the house stands to make $4. While the RTP does tell you how much you can expect to win back out of the $ you wagered, in the earlier example, it does NOT tell you how often or how soon you can Game of thrones slots instagram to win it back.

      All of it is driven by the use of the RNG, at the end of it.

      That is what determines the fairness quotient and levels the playing field: your chances of winning on a particular spin are exactly the same as Slot machine emp jammer parts list chances of losing.

      Slots and the Price Associated with Them

      Each slot has a price, for both the player and the operator.

      For the player, the price is the cost per spin. So for a 50 cent spin, the price he sees is the 50 cents he pays. For the operator, on the other hand, the price would incorporate not just the cost per spin but other factors like the house edge. So, for a game with a 5% house edge, the price for the operator would primarily be the 5% they collect on each spin over a period of time.

      Slots and Human Psychology

      There is another level of science involved when it comes to playing slots: psychology. There have been numerous studies conducted on this, How does online slot machines work focusing on human behavior.

      It is as simple as the results of an experiment Skinner conducted in the s: pigeons were caged and rewarded with food when they pressed a lever. The reward was random, and this made the pigeons hit the lever frequently, not knowing when they would win reward and hoping to win it every single time.

      Another scientist, Natasha Dow Schull, a cultural anthropologist, has actually identified some of the features – called the trigger features – land-based casinos use to grab the attention of players and keep them hooked.

      Here are a few that we have always known about but never associated with the scientific aspect:

      • Screen type: Screens with soft color patterns and an inclination of 38 degrees ensure you don’t hurt your eyes and help preserve energy.
      • Sound: Most of the sounds in a slot machine are sweet music to the ears. There is a science to this, which most of us aren’t aware of: the sounds are generated in the C key, which has a pleasant ‘sound’ to it.
      • Location: The location and setting of a slot machine are designed to ensure privacy and give you a shot at playing some long sessions
      • Button usage: The button gives you a sense of control, of executing a task on your own, as does a lever.

        When you score a win you feel validated, and when you don’t, you feel the need to score one on the next spin.

      • Near misses: Near misses are a big factor in getting you to place the next bet. They give you the feeling of having lost out narrowly and therefore the need to correct that the next time around.
      • Low bets: The first thought when you see a penny slot is that you can have some fun here because it just costs well, a penny!

      The Psychology of Winning

      The great thing about slots is that there are thousands of games to play, and even more ways to win.

      No studies are needed to prove the obvious psychological fact that everyone loves winning.
