Charles Fey Makes the Liberty Bell Car mechanic Charles Fey is widely regarded as the inventor of the first mechanical slot machine, although there is quite a bit discrepancy surrounding the year he made the first cast iron Liberty Bell. It was the first slot machine of its kind to feature an automatic payout feature. The origins of slot machines can be traced back to the late 19th Century. The first slot machine was developed by the New York based company, Sittman and Pitt in The game had 5 drums with a total of 50 playing cards. The machine could be found in many bars, and cost a nickel to play. On August 8, , Schultze had patented his own “coin-controlled apparatus,” called the “Horseshoe.” This was the first US patent issued for a gambling machine and was the first to somewhat resemble what we now know as a modern slot machine. The Liberty Bell is arguably the first slot machine for gambling with automatic payouts. It was invented in by Bavarian-born Charles Fey in San Francisco, California. This slot machine simulated the card game of poker, having three spinning reels each with five symbols: diamonds, hearts, horseshoes, spades, and an image of the Liberty Bell. The first slot machine was invented by Charles Fey in San Francisco California U.S. in Many, however, believe that Charles Fey completed the first slot machine in The original machine was of course much simpler mechanism.
The one-armed bandit is another popular nickname. The first mechanical slot machine was the Liberty Bell, invented in by car mechanic, Charles Fey — of San Francisco.
The Liberty Bell slot machine had three spinning reels. Diamond, spade, and heart symbols were painted around each reel, plus the image of a cracked Liberty Bell.
A spin resulting in three Liberty Bells in a row gave the biggest payoff, a grand total of fifty cents or ten nickels.
Other Charles Fey machines include the Draw Power, and Three Spindle and the Klondike. In , Charles Fey invented the first draw poker machine.
Charles Fey was also the inventor of the trade check separator, which was used in the Liberty Bell. The hole in the middle of the trade check allowed a detecting pin to distinguish fake nickels or slugs from real nickels.
The demand for Liberty Bell slot machines was huge. Fey could not build them fast enough in his small shop. The original machine was of course much simpler mechanism.
It consisted of three spinning reels containing a total of five symbols, Horseshoes, diamonds, spades, hearts and a bell Liberty Bell , from which this machine took its name.
By replacing ten cards with five symbols with three reels instead of five drums, the complexity of reading a winning result was significantly reduced, allowing Fey to develop an effective mechanism of automatic payment.
Three bells in a row produced the biggest payment. Liberty Bell was a huge success and has created a thriving industry of mass production of gaming machines.
Even when the use of these gambling devices, banned in his home country after a few years, Fey still could not meet demand for the game elsewhere.
The Liberty Bell was so popular that it was copied by many slot machine manufacturers. Thus in , manufacturer Mills from Chicago produced a slot machine the Operator Bell.
The Sitman and Pitt of Brooklyn, New York , U. It contained five drums holding a total of 50 card faces and was based on poker.
This machine proved extremely popular and soon many bars in the city had one or more of the machines.
They inserted the currency and pulled the lever which turned the drums and the cards they held, while the player hoped a good poker hand.
There was no direct payment mechanism, so a pair of kings might get the player a free beer, whereas a Royal Flush cigars or drinks.
The awards were entirely depended on the offers in each local installation. The minimum theoretical payout percentage varies among jurisdictions and is typically established by law or regulation.
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.
Within some EGM development organizations this concept is referred to simply as "par". Play now! 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. 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.
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.
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 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 Technology Red 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.
In contrast the payout occurs only on average of once every 6, plays. 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. 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. 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.
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.
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.
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.
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.
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.
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".
Malfunctioning electronic slot machines are capable of indicating jackpot winnings far in excess of those advertised. 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.
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.
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.
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.
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.
For a detailed list of state-by-state regulations on private slot machine ownership, see U. 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. In Australia "Poker Machines" or "pokies"  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.
In the Australian Productivity Commission reported that nearly half Australia's gaming machines were in New South Wales. Australia ranks 8th in total number of gaming machines after Japan, U.
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. State of Nevada, which legalised gaming including slots several decades before N. This new law also banned machines with an automatic play option.
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,  and banning slot machines with spinning reels entirely.
This policy had an extensive political history, reaffirmed by the Royal Commission into Gambling: . 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 2.
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 Gillard Labor government following the hung parliament result. Wilkie immediately began forging ties with Xenophon as soon as it was apparent that he was elected.
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. 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.
Slot machines are covered by the Gambling Act , which superseded the Gaming Act Slot machines in the U.
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 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. 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 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. It is known for machines to pay out multiple jackpots, one after the other this is known as a streak or rave 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.
