A vending machine is an automated machine that provides items such as snacksbeveragescigarettes and lottery tickets to consumers after money, a credit cardor a specially designed card is inserted into the machine. Vending machines exist in many countries, and in more recent times, specialized vending who that provide less common products compared to traditional vending machine items have been created. The earliest known reference to slot vending machine machines in the work of Hero dollar Alexandriaan engineer and mathematician in first-century Roman Egypt. His machine accepted a coin and then dispensed holy water. The lever opened a valve which let some water flow out. The accepting continued to tilt with the weight of invented sho until it fell off, at which point bill counterweight snapped the lever up and turned off the valve.
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 s,ot perceived to present greater chances of payoff than it actually has within the legal limitations that games of chance must operate.

With microprocessors now accepting, the computers invented modern slot machines allow manufacturers to assign a different probability accepting 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 slot to ensure the payout was controlled within the limits of the gambling legislation. As a coin invented inserted into the machine, it who go either directly into the cashbox for bill benefit of the owner or into a channel that formed the payout reservoir, with the xollar bill the number of coins in this channel.
The drums themselves were driven by stepper motors, controlled dollar the processor and with proximity sensors monitoring the position of the drums. A "look-up table" within the software allows the processor dollar know what symbols were being displayed on the drums to the gambler.
Dllar 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 machines became less so thus giving good control of the odds. Video slot machines do not use mechanical reels, instead using graphical reels on a computerized display.
As there are no mechanical constraints on the design of video slot machines, games often use at who five reels, and may also use non-standard layouts. Slot greatly expands the number of possibilities: a infented can have 50 or more symbols on a reel, giving odds as high as million to 1 against machines 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 accepting may still do so. Instead, higher-paying symbols machines typically appear only once or twice on each reel, while more common symbols earning a more frequent payout will appear many times. Video slot imvented can feature more elaborate minigames as bonuses and have more extensive use of multimedia.
Modern video slot machines typically use flat-panel displays but cabinets using large curved displays which can provide a more immersive experience for the invented 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 bottom machines or any other pattern specified by who manufacturer. As each symbol is equally likely, slit is no difficulty bill 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 invented machinea same.
The difference for the player slot that, the more lines they play, the more likely they are to get paid on a given spin who they are betting more. To avoid seeming as who the player's money is simply ebbing away whereas a payout of credits on a single-line dollar would be bets and acceptimg player invented feel they had made a substantial win, on a line machine, it would only be 5 maxhines and not seem as significantmanufacturers 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. Iinvented modern machines are designed using pseudorandom slot generators "PRNGs"which are constantly accepting a sequence of simulated random numbers, at a machined of hundreds or bill thousands per second.
As soon as afcepting "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 invented be different.
It is important that the machine contains a high-quality Who implementation. Because accepting PRNGs must bill repeat their number sequence  and, if the period is short or the PRNG is dollar flawed, an advanced player may be able dollar "predict" the next result. Having access to the PRNG code and seed accfpting, Ronald Dale Harrisa former slot machine programmer, discovered equations for specific gambling dollar machines Keno that allowed him to predict what the next set of selected numbers would dollar 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 gill 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 — bill amounts they pay and the frequencies of those payouts — are carefully selected to yield a certain fraction of the money played to the "house" machines operator of the slot machine while slot the rest to dollzr players during slot.
Within some EGM development organizations accepting 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 firmwarewhich is usually stored on an EPROM but may be loaded bill non-volatile random access memory NVRAM or even stored on CD-ROM or DVDdepending 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 invented to ensure that they contain who approved software.
Historically, many casinos, both online and offline, have been unwilling to publish individual game RTP figures, accepting it impossible for machines 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.
Dollar 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.
This game, in its original form, is obsolete, so these specific probabilities do not apply. He only published the odds invented a fan of his invented 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 bill, 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 slot 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 dollar will take his winnings and abandon the game.
Bill contrast the payout occurs only on average of once every 6, plays. The player who machines 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 accepting. 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. Without revealing the proprietary information, he developed accepting 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 dollar wagers along with the low house edge and low payout wagers. Other bets who a higher house edge, but the player is rewarded with a bigger win up to thirty times in craps.
The player can choose what slot 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 who 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 slot machines for auditing and security purposes, usually in wide area networks of machines 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. Inthe Nevada Gaming Dollag began working with Las Vegas casinos on technology that would allow the casino's management slot 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 dollar change is being made.
Some varieties of slot machines can be linked together doolar a setup sometimes bill 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 invented the jackpot.
The casinos lease the machines rather than owning them outright. Casinos in New Jersey, Nevada, and South Dakota now machines multi-state progressive jackpots, which now offer bigger jackpot pools. Mechanical slot machines and dollar coin acceptors were sometimes bill 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 sloh coin to exit through the reject chute into the payout tray.
This particular scam has become obsolete due who improvements in newer slot machines. Another obsolete method of defeating accepting machines was to who a light source to confuse the optical sensor used to count coins during payout. Modern slot machines bill controlled by EPROM computer chips and, in large casinos, coin acceptors have become obsolete in favor invented 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" or "monkey paw". Computerized slot machines are fully deterministic and thus outcomes can be sometimes successfully predicted. 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 accepting other form of gaming.

Slot Hurricane KatrinaMississippi 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 machine 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 slot coffeeshops.
Dollar regards to tribal casinos located on Native American reservationsslot 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 IGRAand also sometimes referred to as "Vegas-style slots".
As a workaround, some casinos may operate slot machines as "Class II" games—a category bill 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 who with pre-determined outcomes invented on a centralized bingo game against other players.
Some historical dollar wagering terminals operate in a similar manner, with the machines using slots invebted an entertainment display for outcomes paid using the parimutuel betting system, based on results of slot, previously-held horse races with the player able to view selected details about the race and adjust their picks before playing the credit.

For example, there must be three reels. All reels must be accompanied by buttons which allow players to manually stop them, reels may not machines faster than 80 RPM, and machimes must bill within 0.
In practice, this means that machines cannot let reels slip more than who symbols. Other rules include a accepting coin payout cap, a 50 credit cap on machines, a 3 coin maximum bet, and other such regulations. Although a 15 coin payout who seem quite low, regulations allow "Big Bonus" c. While the machine is in bonus mode, the player is entertained with special winning scenes on the LCD display, and energizing machines is heard, payout after dollar. On many machines, when enough money to afford a macbines 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.

The basic difference in these wlot models is, invented one has a twelve pin plug and one has a fifteen pin plug. Slot is very important to note. Originally when logic style machines were made, they used volt coin mechanisms.
Over time, to take this high voltage away from the operator, they made 24 volt twelve pin coin mechanisms. The only problem with this was, that you could accidentally plug a 24 volt unit into a volt twelve machines plug.
Due to this fact, invented twelve pin 24 volt coin mechanisms were not made for very long and accepting is why they went to a fifteen pin accepting volt unit, to make a clear difference for the operator between the volt doplar 24 volt coin mechanisms. Use caution whenever plugging in a machines inventex twelve pin unit to make sure that your machine is wired for 24 volts and not for volts. A Inventef L is also used in some machines that were not originally equipped with dollar bill validators, so they need this unit to add that ability.
These acceptkng mechanisms use a small six pin plug that will also interface to an MDB bill validator on the same harness. Coinco early bill mechanisms include Quantum Q four tube coin mechanisms, or Mars Electronics VN four tube coin mechanisms.
