Technology Reels

Until recently, all machines, mechanical rotary drums are used to display the results and findings. Although the original machine used five reels, simpler and therefore more reliable, three drum machines quickly became the standard.

The problem with three drum machine is that the number of combinations is only cubic - the original machine with three reels and 10 symbols of individuals on each reel had only 103 = 1,000 combinations. This limited the ability of the manufacturer to offer big wins, as even the rarest event could happen every 1,000 pieces. The maximum theoretical payout, assuming 100% return to player is 1000 times the plant, but which leave no room for any other pay, which makes the device very high risk, and also quite boring.

Although the number of symbols eventually grew to about 22 allowing about 10,000 combinations, it is still limited size of the jackpot, as well as the number of possible outcomes.

In 1980, however, automated electronic equipment manufacturers in their products, and programmed to weight the various symbols. In this way, the chances of loss of symbols appearing on the payline is disproportionate to their actual frequency on the physical reel. The symbol will only appear once a player appears on a roll, but may in fact takes a few stops on the multiple reel.

In 1984 Inge Telnaes received a patent for a device called "Electronic Device Using the Random Number Generator Game Reel choice position settings. IGT International Gaming Technology bought the Telnaes patent, and now all manufacturers gaming machines, using what has become known as mapping or mapping Talnaes roll must license the patent from IGT. 1984 was granted a patent for this technology (UStates Patent 4 448 419) ] states: "It is important that the machine that is perceived to present greater chances of payments than it actually is no legal restrictions on gambling, it must work. , the virtual reel may have up to 256 virtual stops per reel, allowing 2563 = 16777216 final position. The manufacturer may choose to offer million dollar jackpot of $ 1 bet, convinced that only the 16.7 million units each.
Computer

The chip, now ubiquitous, computers inside the modern machines allow the manufacturers to assign a different probability for each symbol on each reel. For a player can prove that the winning symbol is "so close", when in fact the probability is much lower.

In modern machines, the reels and lever are for historical reasons, and entertainment.

Video Slot

Video slot machine is the latest innovation, with no moving parts at all - instead of the graphical representation is displayed on the screen. Since the player is basically a computer game, manufacturers are able to offer more interactive elements, such as advanced bonus games and advanced video graphics.

In addition, because there are no restrictions on the construction of mechanical slot machines to video games, mostly displaying five reels, rather than three. This greatly increases the number of possibilities: the machine may have 50 or more symbols on the reel, making a rate as high as 300 million, 1 against - enough to even the largest jackpot. As there are so many combinations given by the five reels, manufacturers do not have to repay the importance of symbols (although some may still do). Instead of paying more symbols there are usually only once or twice each role, while the more common symbols, winning more and more frequent payments, appears many times.

Video slot machines typically encourage the player to play a lot of "lines", so instead of simply the average of the three symbols displayed on each reel, the line can go from bottom to top from left to right, or any of the designs specified by the manufacturer. As each symbol is equally likely, there is no difficulty manufacturer allows the player to take all possible directions or to offer - long-term return for the player will be the same. The difference for the player is that the more lines of the game the more likely it is to make money on the spin - but of course there are more plants in the first place.

To resist the impression that the player the money is simply run-off (whereas the payment of 100 credits on a single machine line will be 100 plants, and the player will feel that they made a significant victory, on a computer with 20 lines, only the five plants and does not seem important), manufacturers generally offer a bonus game that can many times their bet. The player is encouraged to play the game in order to achieve a bonus: even if it loses the bonus game may allow him to recover his losses.

random numbers

All modern machines are designed using a pseudo-random number generator ("PRNGs"), which are constantly generating random numbers, amounting to hundreds or perhaps thousand 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 depends on exactly when the game is played. Fraction of a second sooner or later, and the result would be different.

It is important that the device contains high-quality implementation of the RNG, because in the end all PRNGs must repeat their numbers (see The Art of Computer Programming Volume 2 Chapter 3, random numbers), and if the period is short, or otherwise defective PRNG player can benefit be able to "predict" next to the result. Having access to the PRNG code and value of seed Ronald Dale Harris, a former slot machine programmer, discovered the equation for the various games of chance such as keno, which allowed him to predict what the next set of numbers will be based on previous seasons.

Most of the machines have to overcome this by generating a number, even if the device is not used, so a player can not tell where in the order, even if you know how the machine has been programmed.

Payment of interest

Vending machines are typically programmed to pay winnings and 82% to 98% of the price that ranked by players. This is known as the "theoretical payout percentage" or RTP, "back to the player." The theoretical minimum interest payment varies between legal and is usually determined by law or regulation. For example, the minimum payout in Nevada is 75%, in New Jersey, 83%. The winning patterns on slot machines - the amount of their pay and the frequency of these payments - are carefully selected in order to obtain a specified proportion of money to talk to the "house" (the operator of gaming machine), while the return to rest players during the game. Suppose that a machine costs $ 1 per spin. Can be calculated that for a sufficiently long period of time, eg 1 million turnover, the machine will return an average of $ 950,000 for their players who have inserted $ 1,000,000 during that time. In this (simplified) example, the machine is said to pay 95%. The operator keeps the remaining $ 50,000. In some organizations EGM development of this concept is called simply "par". "Par" also manifests itself to the players as promotional techniques: "Our 'Loose Slots' have a 93% return! Play Now!" It is worth noting that the "Loose Slots" actually may describe very few anonymous machines EGMs in the bank.

Automatic theoretical percentage of victories in a factory, where a program is written. Change in percentage of victories after the machine was placed on the floor, the game requires the physical exchange of software or firmware, which is usually stored in the EPROM, but it can be loaded into non-volatile RAM (NVRAM) or even stored on CD-ROM or DVD, depending on the computer capabilities and requirements. Based on current technology, it is time-consuming process and as such is rare. In some countries, like New Jersey, the EPROM has a tamper-evident seal and can be amended only in the presence of officials of the Gaming Control Board. Other countries, including Nevada, randomly audit machines to ensure that they contain only approved software.

Back to the player, not just statistics, it is in the interest. The probability of each payment of wages on the table is critical. For example, consider a hypothetical machine with many different values in the table wages. However, the probability of obtaining all payments are zero except the highest. If payment is 4,000 times the amount of entry, which happens an average of 4,000 times, the player is back to exactly 100%, but the game will be boring to play. Furthermore, most people do not win anything, and after the entries in the table payments, which would be confusing to return to zero. How these individual probabilities are closely guarded secrets, it is possible that the machines advertised with high player simply go back to increase the likelihood of winning. Casinos can legally place machines of a similar style of advertising payments and that some machines have a 100% return to player. Another advantage is that large jackpots increase feelings of other players.

Table of probabilities for a given machine, called Reel payslips and sheets, or the Pars. Odds Wizard Pars revealed one commercial machine, original games, International Technology Machine Red White and Blue. This game, in its original form, is obsolete, so these specific probability do not apply. Only after he published a fan of his courses he sent some information on the gaming machine that was sent to the computer in the Netherlands. Psychology of construction machinery quickly revealed. There are 13 possible withdrawals from 1:1 to 2,400:1. Payout is 1:1 every 8 units. 5:01 payout is at 33 units, while the payout is 2:1 at 600 units. Most players at each other increases the probability proportionate to the payment. First, the average payout, which aims to give the player experience 80:1 payout. Is programmed to occur on average once every 219 units. 80:1 payout is high enough to create excitement, but not so high that it makes the probability that the player will win and give up the game. More than likely, the player began the game with at least 80 times his bet (for example, there are 80 quarters in $ 20). In contrast 150:1 payout only occurs on average once per 6,241 units. 2,400:1 highest payout only occurs on average once every 643 = 262,144 plays on a virtual machine has 64 stops. The player who continues to feed the machine may have several medium-sized payments, but should not have a big payout. It closed after it is bored or does not have the bankroll

Despite the fact that they are confidential, sometimes Pars sheet can be found on the website. Are of limited value for the player, because usually the machine will be from 8 to 12 different programs with different payment options. In addition, minor differences for each machine (ie a double play wins or five times) are always under development. Casino operator may choose to install the EPROM chip in each particular machine to select the desired payment. The result is that there is really no such thing as high return type of machine, because every computer has potentially many settings. From October 2001 to February 2002, columnist Michael Shackleford PAR sheets obtained in five different machines nickel, four games IGT Austin Powers, Fortune Cookie, Leopard Spots and Wheel of Fortune, and one game manufactured by WMS, Reel em "Without disclosure W. proprietary information, has developed a program that will allow him to determine less than usual dozen or so plays on every computer that was installed EPROM chip. Then he made a survey of over 400 machines in 70 different casinos in Las Vegas. On average, the data and assigns the average percentage of return investment in machinery in any casino. The resultant list was made public for marketing purposes (especially the Palms Casino, which the top ranking)

One of the reasons that the machine is so profitable casino is that a player must play at a high house edge and high payout bets with low house edge bets and low payments. In the more traditional games such as craps bets, the player is aware that some plants are almost 50/50 chance of winning or losing, but pay only a limited number of original plant (usually not more than three times). Other casinos have higher betting, but the player is rewarded with a higher win (up to thirty times in the bone). The player can choose what company wants to do. Paypal does not provide such opportunities. Theoretically, the operator can make these probabilities are available, or allow the player to choose which of them so that the player has a choice. However, the operator never adopted this strategy. Different machines have different maximum payment, but without knowing the chances of the jackpot, there is no rational way to differentiate.

In many markets where central monitoring and control systems are used to connect devices to control and protection, usually in wide area networks many places and thousands of machines, the player must return typically changes from a central computer, not on every machine. Range of rates is in software games and parties at a distance.

In 2006, the Nevada Gaming Commission began working with Las Vegas on technology that would allow the casino management to change the game, rates and payments remotely. Changes can not be done immediately, but only after the selected machine has been idle for at least four minutes. After the change, it must be closed to new players for four minutes and display on-screen message informing potential participants that the change is made

Machines Linked

Machines are often linked together in a way that allows a group of machines to offer a particularly large prize, or "jackpot". Each machine in the group contributes to this small amount of the progressive jackpot, awarded to a player who gets a Royal Flush, for example, the video poker machine or a certain combination of symbols on a regular or nine-line machine. The amount paid for the progressive jackpot is usually much higher than any single machine could pay on its own.

In some cases, multiple computers are connected in many casinos. In these cases, machines may be owned by the manufacturer, which is responsible for paying the jackpot. Casinos leasing, rather than having them directly. Megabucks may be the most famous example of this type of machine. Megabucks Nevada starts at $ 10,000,000 jackpot. (Before September 2005, Megabucks Nevada reset to $ 7,000,000.) The new penny Megabucks video game also has a jackpot that starts at $ 10 million.

Fraud

mechanical devices and slot coin acceptors were sometimes susceptible to fraud and extortion of other devices. One historical example involved spinning coin with a short length of plastic pipe. Weight and size of the coins will be accepted by the device, and credits will be issued. But a spin by plastic wire will cause the coin to exit through the reject chute into the tray payments. This particular fraud has become obsolete because of the improvement in newer machines.

Modern slot machines are controlled by computer and EPROM chips, in large casinos, coin acceptors have been rendered obsolete by bill acceptors. These machines and their bill acceptors are designed advanced anti-cheating and anti-counterfeiting measures and are difficult to cheat. Slot games at the beginning of time have been deceived by the use of fraudulent devices, such as "zip" or "monkey paw" used by well-known machine cheat Tommy Glenn Carmichael. However, more recent attempts to cheat slot machines include manipulating the EPROM, such as microwave ovens, directing him to hinder its proper functioning. Casino Interior, such as Ronald Dale Harris also discovered manipulating the software in machines in order to defraud casino operators.
