Slot MachinesThe slot machine was invented back in the late 19th century but the history of machine manipulation is only just over 50 years old. Initially, they only paid The first electromechanical games offered the possibility to stop the reels themselves. Charles Fey invented the first slot machine in in California.

The First Slot Machine Was Invented In What Year Your Expert Guide About the History of Slots Video🔷 Professor Random talks about Slot Machine PAYBACK % \u0026 How to find Loose Slots Many, however, believe that Charles Fey completed the first slot machine in These new restrictions resulted in slot machines having the aforementioned non-cash payouts of fruit-flavored gum. IGT's William Redd took over the Fortune Coin Company and improved the flagship slot machine's RNG. It is a purely informational website that does not accept Spiele Kostenlos Star Wars of any kind. It was a key loophole that allowed major rivals like Caille Brothers, Mills Novelty Company, and Bally to muscle in.
It weighed a staggering lbs and was able to handle paying out hundreds of coins in one go. It was hugely popular.
Las Vegas-based Fortune Coin Company developed Fortune Coin, the first ever video slot, and gave everything a futuristic leap.
Some players found it took a bit of getting used to, though, as they were more familiar with the mechanical spinning reels.
It was later modified and cheat-proofed with the addition of random number generators RNGs when it was bought by IGT in IGT's William Redd took over the Fortune Coin Company and improved the flagship slot machine's RNG.
By the end of the 70s, Fortune Coin had a better RNG, more paylines, and promised bigger payouts. It was soon a regular feature along the Las Vegas strip.
IGT were on a roll after the success of the upgraded Fortune Coin, but it was when Megabucks caught on that things really took off. The world's first linked progressive slot , Megabucks, had top prizes that were linked across multiple machines.
By the end of the decade, IGT had introduced several progressive machines including Wheel of Fortune, based on the hit TV gameshow. WMS Industries Inc.
WMS developed its first video slot with a second screen bonus. Reel 'Em In featured a fishing theme where players were able to trigger a Pick'em style bonus game.
It paved the way for second screen bonuses like free spins for years to come. A speedier and cheaper internet allowed online gambling manufacturers to start developing slots that could be played at home.
Microgaming had already been operating an online casino since but launched Cash Splash in , one of the world's first ever online progressive jackpot slots.
As broadband speeds and operating systems improved, the number of developers grew. Major players like NetEnt, Playtech, and Play'n GO all started up operations in the s and continue to innovate and expand.
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. Other early machines, such as trade stimulator, were distributing profits in the form of chewing gum with fruit flavors, depending on the tastes which appear on the cards of the game.
The popular cherry and melon symbols derive from this machine. The symbol BAR, most common and widespread on slots came from the company logo Bell-Gum Fruit.
The payment of food prizes was a commonly used technique to avoid laws against gambling in the States.
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. 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.
This limited the manufacturer's ability to offer large jackpots since even the rarest event had a likelihood of 0. Although the number of symbols eventually increased to about 22, allowing 10, combinations,  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 ,  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.
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. 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 do not use mechanical reels, instead of using 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.
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 he is losing, the bonus game could allow then to win back their losses.
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  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.
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.
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.
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.It was Charles Fey who created the first slot machine in The history of slots began in when Charles Fey invented the slot machine.

This was the year when the first true slot machine was invented by Charles Fey in California. It had only 3 reels, it had much simpler mechanism, a total of just five reel symbols and could give automatic payouts. The biggest win was ten nickels. It was named Liberty Bell and had much greater success than its predecessor. 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.
