Understanding the Algorithms Behind Slot Machines

Slot machines are loved all around the world. It takes a whole lot of work for them to get created and released to the public. Most of today’s slot machines are controlled by a central computer that is inside the machines. It is not controlled by the motion of reels. Step motors are used to turn each of the reels. They are also used to stop the reels at predetermined reels. Digital pulses of electricity drive the step motors.


The electric motor is driven by a fluctuating electrical current. All of the game machines today are designed to play players back a percentage of what was played. The amount varies depending on the casino. The longer a machine is played, the closer the payouts are to the theoretical results.


The machines have a random selection process. This selection process is done to achieve a set of theoretical odds. Each time a lever is pulled and the reels are in motion to combine a set of symbols, this means a random selection has occurred. Random selections makes sure that the results from a previous pull and ones before that do not have an effect on the current one.


Theoretical odds are developed into the designs and programs of the machines. It is possible to calculate exact payout percentages for the machines over a long period of time.


Slot machines have reels with symbols on each one, except for video slots. Each symbol that is on a reel represents a stop that can rest on the payline. However, it may or it may not be part of a combination that creates a payoff.

The chances of winning any payoff on a slot is based on the number of reels and the number of symbols that are on each reel. Most mechanical slots have three reels with 20 symbols on each one. In order to calculate the total number of combinations on a machine, the number of symbols on all of the reels gets multiplied by the number of stops on the remaining reels. In a three reel that has 20 stops per reel, that means that there is a 20x20x20 (8,000) combination of slot symbols.


For jackpots that pay on a 7 7 7 and there is only one 7 on each reel then the chances of hitting the jackpot is 1/20×1/20×1/20 (8,000). When there are two 7 symbols on a reel, then the calculation is 2/20×1/20×1/20. This would mean a 1/4000 chance of hitting the jackpot payout.


On a micropressor controlled slot, it is harder to calculate the probabilities. Determining the payoffs of a machine that is micropressor controlled would require a lot of reverse engineering. The number of reels that is on a game has a greater affect than the number of symbols each reel. For instance if there is 32 stops on each reel with 3 of them then the calculation would be 32x32x32, which equals out to be 32, 768 combinations. If a machine has a 22 stop per reel and 4 reels, then the calculation would be 22x22x22x22 which equals out to be 234,256 combinations.


A lot of people misinterpret when they hear the words “our slots pay back 98.3%. Unfortunately this not really the case. Really this means that over a long period of time for each dollar that gets inserted into the machine, it returns 98.3 cents. The misinterpretation of this is what helps causes a lot of people to put too much money into the machines. Putting too much money into the machines can cause a lot of financial problems. A lot of financial problems can lead to other problems developing. This is something that everyone who decides to gamble must realize. Hence why it is also important for those who decide to gamble to put themselves on a limit. Putting themselves on a limit will help them make sure they do not go overboard. Every dollar that is played, the casino keeps 1.7 cents. The percentages can only be true over consisting hundreds of thousands or sometimes even millions of times being played. Machines continue to grind away all of the money that has been played over long terms.


The chances of winning a big payout on a slot is very slim. However, many gamblers do not realize this until it is unfortunately too late. The probability of winning on a slot game is heavily based on math. Math plays a very big role in determining chances of payouts. When people are playing slot games, they have a high hope that they will the big payout and/or win the money they lost. In reverse when gambling the hope itself of winning big can also in a way draw in excitement. However, gamblers should not let the excitement of hoping to win big overcome reality.
