Modern casino slot machine games are controlled by computer chips and software, and the winner %s are preprogrammed into the gaming software.

Casino slot machine games have Random Number Generators which are constantly generating combinations, even when the game is not active.

Running in unison with the RNG of the casino slot machine game is the pay out rate percent.

The pay out % controls how much the one-armed bandit will pay, for e.g. the payout per cent may be ninety per cent, meaning the slot machine game will payout ninety percent of all the bets played, … the casino only gets to keep 10 per cent.

This does not imply that every time you bet ten credits you will receive nine in return – where’s the fun … exhilaration in that? Instead, the casino slot machine game just won’t pay out for a bit, and then suddenly jump on a hot streak and you might hit a big jackpot prize.

The pay off percentages will most likely vary between the alternate games and a handful of the highly popular casinos, like Golden Online Casino, which gives a payout rate of up to 95 %!

Hence, in essence, the one-armed bandit takes all the money played into it and pays it out to some fortunate winners. The casino only gets to keep a relatively tiny percent of all the stakes made.

The casino slot software controls every single part of the machine, from the flashing lights to the revolving of the reels.

When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
