Modern casino one armed bandits are controlled by computer software, and the winner percentages are preprogrammed into the computer software.

Casino slot machines have Random # Generators which are continually generating combos, even when the slot machine is not currently being played.

Running side by side with the Random Number Generator of the casino slot machine game is the pay out percentage.

The pay out per cent controls just how much the one-armed bandit will pay out, for eg the payout percent may be 90%, meaning the slot game will payout ninety per cent of all the stakes played, … the casino only gets to keep ten per cent.

This doesn’t mean that for every time you bet ten credits you will receive 9 in return – where is the fun and excitement in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly start up a hot streak and you might catch the big grand prize.

The pay out percentages usually will vary between the alternate games and some of the extremely famous casinos, e.g. Golden Online Casino, which offers a pay out rate of up to 95 percentage!

So, in essence, the slot machine game takes all the funds played into it and pays it out to several chosen winners. The casino only gets to keep a considerably indistinct percentage of all the stakes put out.

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

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