How to calculate return percentage in slot machines

Most gambling games, unlike slot machines, have rules. The machines are regulated by a randomizer – a microprocessor with a programmed random number generator. It is because of such a device that it is extremely difficult to determine even the approximate percentage and amount of winnings without having the technical data of the slot.

Michael Shackleford and calculating the return percentage of slot machines

A slot is a reel (real, drawn or virtual), which, by spinning, produces various combinations of patterns or symbols. In some cases, due to certain numerical errors in calculating the chance, the payback percentages can be extremely low. In this regard, casinos protect information related to the probability of winning in every possible way.

One day, talented mathematician Michael Shackleford contacted several manufacturers of slot machines and asked them for instructions for them. The information received gave completely contradictory data. The instructions did not indicate which machines it corresponds to, and in which casino the described slots are located. Therefore, it became useless for ordinary players.

After a long time, Shackleford finally managed to determine the winning percentage of slot machines. To do this, he visited many gambling establishments and tried to find a pattern of actions, using the instructions of the gaming machine (multilinear). However, his study only applied to 5-cent machines; Shackleford did not investigate other types of slots. The same mathematician proved that the location of the machine in the gaming room does not affect the chance of winning, that all such rumors are myths and prejudices.

Myths and facts about slot machines

1. All winnings are programmed in a certain way. If you win the jackpot once, you won’t win it again. These assumptions are just speculation, since the chance of winning from each “spin” is the same, fixed.
2. The chance of winning increases if the coins are heated and lie in the machine for a very long time. This assumption is completely untenable, since temperature does not determine the chance of winning.
3. People who have a club card of an institution win less often. And this assumption is wrong. The random number generator, which determines the drop-down combination, absolutely does not care if the attempt was paid for with a coin or a card of a permanent member of the club.

It is worth adding that the rumor about twisted machines is just a myth. Restaurant owners have neither the ability nor the means to reprogram microchips. In addition, the supervisory authorities regularly check the presence of a seal on the microchips in order to close the vending machine if they are missing.
