Modern casino slot machine games 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 combinations, even when the machine is not active.

Running side by side with the Random Number Generator of the casino slot machine is the payout %.

The pay out % controls how much the one-armed bandit will pay out, for e.g. the pay % might be ninety percent, meaning the slot machine will pay ninety percent of all the stakes played, … the casino simply gets to keep 10%.

This is not to say that each time you bet ten credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino one arm bandit just won’t payout for a little while, and then suddenly start up a hot streak and you might draw the big top prize.

The pay off percentages will definitely vary between the alternate games and just a few of the highly famous casinos, such as Golden Online Casino, which tenders a cash payment of up to ninety five percentage!

Therefore, in essence, the slot machine game takes all the dough played into it and pays it out to a number of fortunate winners. The casino only gets to keep a generally low 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 turning of the reels.

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