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

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

Running in sync with the random # generator of the casino slot machine game is the pay out %.

The payout per cent controls just how much the one-armed bandit will payout, for eg the pay out percentage could be ninety per cent, which means the one arm bandit will pay ninety percent of all the wagers played, … the casino only gets to keep ten percent.

This is not to say that for every time you bet ten credits you will receive 9 in return – where’s the fun … fascination in that? Instead, the casino slot machine just won’t pay out for a little while, and then suddenly go on a hot streak and you might draw the big top prize.

The pay off %s will tend to vary between the a variety of games and some of the most common casinos, for example Golden Online Casino, which hands out a pay out rate of up to ninety five percent!

Hence, in essence, the slot machine takes all the cash played into it and pays it out to several lucky winners. The casino only gets to keep a basically low % of all the stakes put out.

The casino one armed bandit software controls each and every part of the machine, from the blinking lights to the revolving of the reels.

When you hit spin on the slot machine game, a combination is generated by the RNG which corresponds to the pictures on the reel.
