Modern casino Slots are controlled by computer software, and the win %s are pre-programmed into the software.

Casino Slots have RNGs which are constantly generating combinations, even when the machine is not currently being played.

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

The pay out % controls how much the slot machine game will pay, for e.g. the pay percent may be 90%, meaning the slot machine game will pay ninety per cent of all the wagers played, and the casino will then get to keep 10 per cent.

This does not imply that every time you bet ten credits you will receive nine in return – where is the fun … thrill in that? Instead, the casino one arm bandit won’t pay out for a bit, and then suddenly start up a hot streak and you might catch the big top prize.

The pay out percentages most likely will vary between the various games and several of the notably acclaimed casinos, for instance Golden Online Casino, which hands out a payout of up to ninety-five %!

So, in essence, the one-armed bandit takes all the cash played into it and pays it out to several chosen winners. The casino only gets to keep a generally low percentage of all the bets made.

The casino one armed bandit software controls every part of the machine, from the flickering lights to the rotating of the reels.

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