Modern casino Slots are controlled by a computer, and the winning %s are preprogrammed into the software.

Casino slot games have Random # Generators that are continuously generating combinations, even when the slot machine is not active.

Running in sync with the Random Number Generator of the casino slot machine is the payout rate percent.

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

This does not imply that every time you bet 10 credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine game just won’t payout for a little while, and then suddenly fire up a hot streak and you might draw the big top prize.

The payout %s will tend to vary between the differing games and a few of the highly famous casinos, like Golden Online Casino, which gives a pay out rate of up to 95 per cent!

So, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a handful of chosen winners. The casino only gets to keep a considerably tiny percent of all the wagers placed.

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

When you hit spin on the slot machine, a combination is produced by the RNG which corresponds to the pictures on the reel.
