Slot machines used to be mechanical, and their inner workings were very simple. The coils were moved by springs and levers. You had an equal chance of getting any of the symbols at any one time.
About 30 or 40 years ago, they changed the way they worked. They look the same in most cases, but they’re bigger and fancier now. And they no longer work mechanically. They are electronic now.
This Is The Basic Functioning Of A Slot Machine:
You can have a game with 10 symbols on each reel. The probability of hitting any of these symbols will be 1/10. Aligning all 3 of any of these symbols will then have a probability of 1/10 X 1/10 X1/10. This means 1/1000.
But since you have 10 different chances, then you actually have a 10/1000, or 1/100, probability of getting 3 symbols lined up on a payline.
The casino has different payouts for different symbol combinations. The only thing all these payments have in common is that they are paying less than the odds of getting that combination. This is how 3win2u casino makes its profit.
A super simple game can have the same payout on every combination – 95 coins. Since it has a 1/100 chance of winning, the casino has a 95% payback percentage. For every $100 the game earns, it will pay an average of $95.
Casinos and designers have different ways of massing these numbers to create whatever percentage return they want. They can, for example, put more symbols on a coil. Since these are just video screens that look like old spinning reels, there really isn’t a limit to the number of symbols you can use.
Designers can also place different probabilities for different symbols. A cherry can only come out every 25 rounds, while an orange can only be set to come out every 5 rounds. The number entered can be anything.
This also allows casinos to offer huge jackpots that they would never be able to physically create and pay out on a mechanical machine. Size limits would certainly not allow this to happen.
Modern slot machines are computerized and use a computer program called a random number generator (RNG) to create the results of what you see on screen. There is no way for you to know what kind of payback percentage a particular slot machine has. In fact, you may be playing identical games next to each other, and they may have dramatic differences in how much they pay.
Some jurisdictions ask casinos to report their payout percentages, but others do not.
