Modern casino one armed bandits are controlled by a computer, and the win %s are preprogrammed into the game software.

Casino slot games have Random Number Generators that are endlessly generating combinations, even when the slot machine is not being played.

Running jointly with the RNG of the casino slot machine is the pay out rate percent.

The pay out percent controls how much the slot machine will pay, for example the pay out % may be 90%, meaning the one arm bandit will pay ninety percent of all the wagers played, … the casino only gets to keep 10 percent.

This does not imply that each and every time you bet 10 credits you will receive nine in return – where is the fun and excitement in that? Instead, the casino one arm bandit just will not payout for a while, and then suddenly fire up a hot streak and you might catch the big jackpot.

The payout %s will definitely vary between the a variety of games and just a few of the very established casinos, for instance Golden Online Casino, which provides a pay out rate of up to 95 percentage!

So, in essence, the slot machine takes all the $$$$$ played into it and pays it out to several fortunate winners. The casino only gets to keep a generally minute per cent of all the odds allocated.

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

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