Modern casino slot games are controlled by computer chips and software, and the winner percentages are preprogrammed into the game software.
Casino slot games have Random Number Generators that are constantly generating combinations, even when the machine is not currently being played.
Running jointly with the random # generator of the casino slot machine game is the pay out %.
The pay out percentage controls just how much the slot machine will payout, for example the payout per cent could be 90%, which means the slot game will pay out ninety per cent of all the wagers played, and the casino simply gets to keep 10 per cent.
This doesn’t mean that every time you bet ten credits you will receive 9 in return – where is the fun and exhilaration in that? Instead, the casino slot machine just will not payout for a while, and then suddenly hit a hot streak and you might catch the big pot prize.
The pay off percentages will vary between the alternate games and just a few of the very famous casinos, like Golden Online Casino, which hands out a pay out rate of up to 95 per cent!
This means that, in essence, the slot machine game takes all the currency played into it and pays it out to some chosen winners. The casino only gets to keep a averagely small percent of all the stakes put out.
The casino one armed bandit software controls any part of the machine, from the flickering lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which relates to the pictures on the reel.
