Random Number Generator
Modern slot machines are computerized. The odds are programmed. In modern slot machines, the reels and lever exist only for historical and entertainment reasons. The positions of the reels are chosen by a Random Number Generator. The machine's software includes a Random Number Generator.
Random numbers are constantly generated by the RNG at an extremely high rate. The most recent random number is used to determine the result when the Play button is pressed. The result is different depending on exactly when the game is played. The result is different every fraction of a second.
The numbers generated by the RNG seem to be not exactly random. Indeed, most RNGs will eventually repeat their number sequence. This behavior is due to poor programming. To build pseudo RNGs with very long periods is relatively easy. There is no computer that is able to complete a single period in the expected lifetime of the universe. Ronald Dale Harris, a former slot machine programmer, was the only one who had access to the pseudo RNG code and seed values. Specific gambling games equations were discovered by him. Then the prediction was made that the next set of selected numbers would be based on the previous games played. But it is impossible for most machines, because numbers are picked by the RNG even when no one plays. So the player cannot see the secquence.
Payout Percentage
Slot machines usually pay out as winnings 82–98 per cent of the money that is wagered by players. This is known as the theoretical payout percentage. The minimum theoretical payout percentage is controlled by jurisdictions. Law or regulation typically establish it. A certain winning pattern is determined by every casino individually. This is the amounts they pay and the frequencies of these pay-outs. The main criterion for selecting the winning patterns on slot machines is that they should yield a certain fraction of the money played to the house. The rest of the money goes to the players.
A slot machine's theoretical payout percentage is set at the factory when the software is written. Physical swap of the software is needed for changing the payout percentage after a slot machine has been placed on the gaming floor. Being a time-consuming process it is done not very often. One can find a tamper-evident seal on the EPROM in certain jurisdictions. To change it Gaming Control Board officials should be present. The audit of slot machines is made by some jurisdictions make sure that they contain only approved software.
The Nevada Gaming Commission is working now with Las Vegas casinos on technology that would allow the casino's slot manager to change the game, the odds, and the payouts remotely. The change can be done 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.
Machines Linking
Linking the machines in a special way is made to offer a particularly large prize, or jackpot. A small amount is contributed by each machine in the group to this progressive jackpot which is given to a player who gets a specific combination of symbols. A single slot machine's jackpot is considerably less than the progressive jackpot.
Multiple machines can be sometimes linked across multiple casinos. In these cases the manufacturer owning these machines is responsible for paying the jackpot.
Near-miss Programming
Computer software controls the reel display of modern slot machines. Combinations that are close to winning combinations can be displayed on the slot machine intentionally.
This practice of showing combinations that are similar to winning combinations more frequently than would occur randomly is called near-miss programming.
A related phenomenon is sometimes called near-miss. The chance of a winning combination appearing on a pay line is controlled by the winning percentages programmed into the slot machine. However, the combinations appearing above and below the pay line are all roughly equally randomly distributed. This means it is much more likely that a winning combination will appear above or below a pay line than on the pay line. This phenomenon only occurs where abbreviated physical reels are used to display a win pattern based upon the RNG. In video slot machines the symbols that appear around the winning line are usually an accurate depiction of how the reels were mathematically modeled.
The issue of a near-miss above or below the pay line was also investigated by the Nevada Gaming Commission. If the near-miss above or below the pay line was not specially programmed it was stated to be legal. That means that the possibility of near-miss occurrence should be equal to the possibility of any other combination. The machine can't show winning combinations more frequently than other combinations above or below the pay line.
In Australia the usage of near-miss programming, where a near miss is inaccurately displayed is also illegal. Manufacturer's practices are audited by regulators with the help of stop motion cameras.
Fraud
Mechanical slot machines and their coin acceptors were sometimes susceptible to cheating devices and other scams.
Coin acceptors have become obsolete in favor of bill acceptors and modern slot machines are controlled by EPROM computer chips. They are designed with advanced anti-cheating and anti-counterfeiting measures and are difficult to defraud. One of the recent attempts at defrauding slot machines is directing microwaves toward it to disrupt its proper functioning.
It doesn’t require much skill to play slots. Slots give you an opportunity to win a lot of money. The main element of all slots is RNG, which determines the outcome. RNG is a Random Number Generator. RNG is a microchip, which is constantly churning out thousands of numbers a second. Even if nobody plays RNG works. When you hit a spin the machine takes the next number out which it then translates into the position which the reels should stop at, and whether you have won or not! Before playing you have to decide how many coins for each go you want to play. If you have enough money or credits you’d better make maximum bets. Playing with maximum bets increases your chances of winning the jackpot. The payout depends on the type of a slot machine.
The first gambling machine, on which all modern slots are based, was invented by Charles Fey in 1887. Instead of symbols we have now there were regular playing card symbols. The gambling machine consisted of three mechanical reels and a lever. The lever had to be pulled to make the reels move. It was Charles Fey who offered the first slot machine to the public. The first slot consisted of three mechanically spinning reels. There were ten pictures (cards) on each reel. The combination of three equal cards was considered to be a winning combination. In 1889 there appeared slots, which gave an opportunity to win the jackpot. Fey’s first slot machine was called the Liberty Bell. The slots were used as an entertainment mostly for ladies. Women played slots while their men gambled. For some time gambling was forbidden. There appeared so-called “Liberty Bell Gum Fruit” slots. With “Liberty Bell Gum Fruit” people could buy a chewing gum and as a bonus they got an opportunity to have a spin. Different fruits were used as the symbols. At the end of the 20th century computerized slots and video poker machines appeared. Modern slots are much easier to use. Gamblers push the button and the game starts. Now playing slots through Internet is available for players from all over the world.
There are many types of slot machine configurations but all work according to the same principles - put the money in the slots and pull the handle! The main classification of slots distinguishes two types of slots: straight and progressive slots. If you play slots then you are paid in accordance with the payout schedule, which is always shown on the slot. Inside the straight slot group four more types are distinguished. They are multiplier, bonus multiplier, multiple payline and buy-a-pay slots. The main feature of multiplier slots is that the payout for a winning combination depends on the number of coins bet. The main principle of bonus multiplier slots is a bonus round, which becomes active if you play with maximum bets. The feature of multiple payline slots is that the number of active payline is dependent on the number of coins being bet. The Buy-a-Pay slots are profitable only if you place maximum bets. The jackpot for Progressive slots is never the same as it grows higher with every coin put in the machine. You can see the sum of the jackpot above the slot machine and it can be huge.
