Modern casino slot games are controlled by a computer, and the winning percentages are preprogrammed into the game software.
Casino slot games have Random Number Generators which are eternally generating combinations, even when the slot machine game is not being played.
Running concurrently with the RNG of the casino slot machine game is the payout %.
The pay out percent controls how much the slot machine will payout, for e.g. the pay per cent might be ninety per cent, which means the one arm bandit will pay 90% of all the stakes played, … the casino simply gets to keep 10 per cent.
This is not to say that each and every time you bet ten credits you will receive 9 in return – where is the fun … excitement in that? Instead, the casino slot machine will not payout for a little while, and then suddenly go on a hot streak and you might hit a big grand prize.
The profit %s usually will vary between the differing games and a handful of the notably established casinos, e.g. Golden Online Casino, which hands out a payout of up to ninety-five %!
So, in essence, the slot machine game takes all the funds played into it and pays it out to a handful of lucky winners. The casino only gets to keep a basically minute % of all the wagers made.
The casino one armed bandit software controls any part of the machine, from the dazzling lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which corresponds to the pictures on the reel.
