Modern casino slot games are controlled by a computer, and the win %s are preprogrammed into the computer software.

Casino slot machines have RNGs which are continuously generating combos, even when the machine is not active.

Running side by side with the RNG of the casino slot machine is the pay out %.

The pay out % controls just how much the one-armed bandit will pay out, for e.g. the pay per cent could be 90%, which means the one arm bandit will pay ninety per cent of all the bets played, … the casino only gets to keep 10 percent.

This really does not mean that every time you bet ten credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine game will not payout for a bit, and then suddenly jump on a hot streak and you might draw the big grand prize.

The profit %s shall vary between the alternate games and some of the highly favored casinos, for example Golden Online Casino, which provides a pay out rate of up to ninety five percentage!

Hence, in essence, the one-armed bandit takes all the funds played into it and pays it out to a number of chosen winners. The casino only gets to keep a basically tiny percentage of all the stakes placed.

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

When you hit spin on the one-armed bandit, a combination is produced by the RNG which associates with the pictures on the reel.
