Modern casino slot machines are controlled by computer chips and software, and the win percentages are pre-programmed into the computer software.
Casino slot games have Random # Generators which are eternally generating combinations, even when the slot machine game is not currently being played.
Running side by side with the Random Number Generator of the casino one-armed bandit is the pay out percent.
The pay out percent controls how much the slot machine game will pay out, for eg the pay out percentage might be ninety percent, meaning the slot machine will pay ninety percent of all the bets played, and the casino will then get to keep ten percent.
This doesn’t mean that each and every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit just won’t pay out for a bit, and then suddenly fire up a hot streak and you might hit a big jackpot.
The payoff %s will definitely vary between the differing games and a couple of the highly established casinos, e.g. Golden Online Casino, which hands out a cash payment of up to 95 per cent!
This means that, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a couple of privileged winners. The casino only gets to keep a basically tiny percent of all the stakes allotted.
The casino one armed bandit software controls each and every part of the machine, from the flashing lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which is linked to the pictures on the reel.
