Modern casino slot machines are controlled by computer chips and software, and the winner percentages are pre-programmed into the gaming software.

Casino slot games have Random # Generators that are constantly generating combos, even when the slot machine is not being played.

Running in unison with the Random Number Generator of the casino slot machine is the payout rate per cent.

The payout percentage controls how much the slot machine game will payout, for example the pay out percentage could be 90%, which means the one arm bandit will pay ninety per cent of all the bets played, and the casino simply gets to keep ten percent.

This doesn’t imply that each time you bet ten credits you will receive nine in return – where’s the fun and fascination in that? Instead, the casino one arm bandit just will not payout for a little while, and then suddenly fire up a hot streak and you might catch the big top prize.

The pay off percentages will most likely vary between the various games and a few of the highly popular casinos, for e.g Golden Online Casino, which provides a payment of up to 95 percentage!

So, in essence, the one-armed bandit takes all the dough played into it and pays it out to a number of lucky winners. The casino only gets to keep a fairly minute % of all the odds allocated.

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

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