Modern casino one armed bandits are controlled by a computer, and the win %s are pre-programmed into the computer software.

Casino slot games have RNGs that are eternally generating combos, even when the slot machine is not active.

Running simultaneously with the Random Number Generator of the casino slot machine is the payout rate percent.

The payout percent controls just how much the slot machine will pay out, for e.g. the pay % might be 90%, which means the slot machine game will pay 90% of all the wagers played, … the casino only gets to keep ten percent.

This doesn’t imply that for every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino slot will not payout for a bit, and then suddenly hit a hot streak and you might catch the big grand prize.

The pay off percentages will tend to vary between the assorted games and just a few of the very famous casinos, e.g. Golden Online Casino, which gives a pay out rate of up to 95 per cent!

Therefore, in essence, the slot machine takes all the money played into it and pays it out to a couple of chosen winners. The casino only gets to keep a basically tiny percent of all the odds made.

The casino slot software controls each part of the machine, from the dazzling lights to the spinning of the reels.

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