Modern casino Slots are controlled by computer software, and the winner percentages are preprogrammed into the software.

Casino slot games have Random Number Generators which are continually generating combos, even when the machine is not currently being played.

Running jointly with the random # generator of the casino one-armed bandit is the pay out per cent.

The pay out per cent controls how much the slot machine will pay, for eg the payout percentage might be 90%, meaning the one arm bandit will pay out 90% of all the stakes played, and the casino gets to keep 10 percent.

This does not mean that for every time you bet ten credits you will receive nine in return – where’s the fun and thrill in that? Instead, the casino slot won’t payout for a little while, and then suddenly jump on a hot streak and you might draw the big top prize.

The pay out %s will very likely vary between the various games and some of the most favored casinos, for example Golden Online Casino, which tenders a cash payment of up to 95 %!

This means that, in essence, the slot machine takes all the funds played into it and pays it out to some fortunate winners. The casino only gets to keep a generally small percent of all the plays made.

The casino slot software controls each and every part of the machine, from the flickering lights to the rotating of the reels.

When you hit spin on the slot machine game, a combination is generated by the RNG which is linked to the pictures on the reel.
