Modern casino slot machine games are controlled by a computer, and the winning %s are pre-programmed into the gaming software.

Casino one armed bandits have RNGs which are continuously generating combinations, even when the slot machine is not being played.

Running synchronously with the random # generator of the casino slot machine game is the payout rate percentage.

The pay out percent controls just how much the one-armed bandit will pay out, for eg the payout per cent may be ninety percent, meaning the one arm bandit will pay ninety per cent of all the wagers played, … the casino simply gets to keep 10 per cent.

This doesn’t mean that every time you bet 10 credits you will receive nine in return – where’s the fun … thrill in that? Instead, the casino slot machine will not pay out for a while, and then suddenly hit a hot streak and you might catch the big jackpot.

The pay off %s will vary between the various games and a couple of the extremely acclaimed casinos, for e.g Golden Online Casino, which puts forth a payout of up to 95 %!

This means that, in essence, the slot machine takes all the money played into it and pays it out to a handful of lucky winners. The casino only gets to keep a considerably tiny % of all the wagers placed.

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

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