> Computer Slot Machines Bonus Round
The RNG
Nowadays slot machines are computerized. The odds are programmed. In modern slot machines, the reels and lever exist only for historical and entertainment reasons. It is a Random Number Generator that chooses the reels positions. There is a Random Number Generator in the machine's software.
The rate of generating random numbers by the RNG is extremely high. The most recent random number is used to determine the result when the Play button is pressed. The result varies 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. The sequence of numbers is repeated by most of the RNGs. Poor programming is its reason. Pseudo RNGs with very long periods canbe built relatively easily. No computer can complete a single period in the expected lifetime of the universe. It was Ronald Dale Harris, a former slot machine programmer, who knew the pseudo RNG code and seed values. It was he who discovered equations for specific gambling games like Keno. 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 numbers can't be exactly found in a sequence.
Percentage Of The Payout
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. Nearly each casino has its own winning pattern. The amounts they pay and the frequencies of these pay-outs are reflected in it. The selection of the slot machines winning patterns is chosen in such a way that it could yield a certain fraction of the money played to the house. The rest of the money goes to the players.
A slot machine's software is written and the theoretical payout percentage is set simultaneously. Physical swap of the software is needed for changing the payout percentage after a slot machine has been placed on the gaming floor. As it is a time-consuming process it is done infrequently. There is sometimes a tamper-evident seal on the EPROM. Only Gaming Control Board officials can change it. 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. Only after the selected machine has been idle for at least four minutes can the change be done. After making the change the machine is locked to new players for four minutes, it displays an on-screen message informing potential players that a change is being made.
Machines Linking
Offering of a particularly large prize, or jackpot becomes possible when a group of machines is linked in a special way. Each slot machine in the group contributes a small amount to this progressive jackpot, awarded 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. The machines are then owned by the manufacturer, who is responsible for paying the jackpot.
Near-miss
The reel display of modern slot machines is under computer software's control. Combinations that are close to winning combinations can be displayed on the slot machine intentionally.
The term near-miss programming is used to denote this practice.
There is a related phenomenon that is also 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. The combinations above and below the payline are all roughly equally randomly distributed. There are roughly equally randomly distributed combinations above and below the pay line. Only if abbreviated physical reels are used to display a win pattern based upon the RNG this can occur. In video slot machines, virtual reels are used and the symbols that appear around the winning line are usually an accurate depiction of how the reels were mathematically modeled.
There was an investigation held by the Nevada Gaming Commission concerning the issue of a near-miss above or below the pay line. They ruled that this was legal, so long as the near-miss above or below the pay line was not specially programmed. In other words, the near-miss must be just as likely to occur as any other combination. Winning combinations aren't supposed to be shown more frequently than other combinations above or below the pay line.
Near-miss programming, where a near miss is inaccurately displayed is not allowed in Australia either. Stop motion cameras are used by regulators for manufacturer's practices audit.
Fraud
Sometimes mechanical slot machines and their coin acceptors seem to belong to cheating devices and other scams.
Modern slot machines are controlled by EPROM computer chips and coin acceptors have become obsolete in favor of bill acceptors. Different advanced anti-cheating and anti-counterfeiting measures have been taken to make it difficult to defraud these machines. One of the recent attempts at defrauding slot machines is directing microwaves toward it to disrupt its proper functioning.
Slots are very easy to play. 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. RNG churns the numbers all the time. 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! Make out for yourself how much you can afford to spend for one go. If you can afford it make maximum bets. If you make maximum bets you have an opportunity to get the maximum win, which for some slots is the Progressive Jackpot. The type of the slot machine determines the payout.
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 player won if three equal cards came out. 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. Later gambling was forbidden for some time. As a result “Liberty Bell Gum Fruit” slots appeared. People used “Liberty Bell Gum Fruit” for buying a bubble gum and with the bubble gum they got an opportunity to win money, they were given a spin. Pictures of 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. Nowadays gamblers can play slots at the comfort of their home.
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! According to the main slot classification there are two types of slots. They are straight slots and progressive slots. If you play slots then you are paid in accordance with the payout schedule, which is always shown on the slot. Straight slots in their turn can be divided into 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 feature of the bonus multiplier slots is a bonus round, which is activated if you make maximum bets. The principle of multiple payline slots is that the number of enabled payline depends on the number of coins bet. The Buy-a-Pay slots are profitable only if you place maximum bets. Progressive Jackpot is the main characteristic of the progressive slots. Progressive jackpot grows with each coin being bet. The jackpot for Progressive slots is always displayed on the top of the machine.
