Modern casino one armed bandits are controlled by computer chips and software, and the win percentages are preprogrammed into the game software.
Casino slot machine games have Random Number Generators that are continually generating combos, even when the game is not currently being played.
Running in sync with the RNG of the casino slot machine is the pay out %.
The pay out percentage controls how much the slot machine game will payout, for eg the pay out % might be ninety per cent, meaning the slot game will payout ninety percent of all the stakes played, and the casino will then get to keep ten per cent.
This doesn’t mean that for every time you bet 10 credits you will receive 9 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 draw the big jackpot.
The profit %s most likely will vary between the various games and several of the very acclaimed casinos, for example Golden Online Casino, which provides a cash payment of up to ninety five %!
Therefore, in essence, the slot machine game takes all the currency played into it and pays it out to some lucky winners. The casino only gets to keep a fairly low per cent of all the gambles put out.
The casino slot software controls each part of the machine, from the flickering lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which is linked to the pictures on the reel.
