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

Casino one armed bandits have RNGs that are eternally generating combinations, even when the slot machine game is not active.

Running simultaneously with the random # generator of the casino one-armed bandit is the payout %.

The payout percentage controls just how much the one-armed bandit will pay out, for e.g. the pay % could be 90%, meaning the slot game will pay ninety per cent of all the bets played, and the casino will then get to keep ten per cent.

This does not mean that for every time you bet ten credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino slot machine game just won’t payout for a bit, and then suddenly start up a hot streak and you might catch the big jackpot.

The pay out %s most likely will vary between the different games and some of the extremely famous casinos, such as Golden Online Casino, which puts forth a pay out of up to 95 %!

Therefore, in essence, the one-armed bandit takes all the dough played into it and pays it out to a number of chosen winners. The casino only gets to keep a basically low % of all the bets placed.

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

When you hit spin on the one-armed bandit, a combination is put together by the RNG which is linked to the pictures on the reel.
