Modern casino slot machine games are controlled by computer software, and the winner percentages are pre-programmed into the computer software.

Casino one armed bandits have Random # Generators which are eternally generating combinations, 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 %.

The pay out percentage controls just how much the slot machine game will pay out, for example the pay out per cent could be ninety per cent, which means the slot machine will pay out 90% of all the bets played, and the casino only gets to keep ten percent.

This is not to say that every time you bet 10 credits you will receive 9 in return – where is the fun … excitement in that? Instead, the casino one arm bandit won’t payout for a while, and then suddenly fire up a hot streak and you might draw the big grand prize.

The payout %s will very likely vary between the different games and several of the very established casinos, for example Golden Online Casino, which offers a pay out rate of up to 95 per cent!

As a result, in essence, the slot machine game takes all the funds played into it and pays it out to some chosen winners. The casino only gets to keep a generally low % of all the stakes allocated.

The casino slot machine software controls every single part of the machine, from the dazzling lights to the circulating of the reels.

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