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

Casino Slots have Random Number Generators that are eternally generating combos, even when the slot machine game is not currently being played.

Running concurrently with the random # generator of the casino slot machine game is the pay out percentage.

The payout percentage controls just how much the slot machine will pay, for eg the payout percent could be ninety percent, which means the slot machine game will pay ninety per cent of all the wagers played, and the casino only gets to keep 10 per cent.

This doesn’t mean that for every time you bet ten credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly fire up a hot streak and you might draw the big jackpot.

The payout %s usually will vary between the alternate games and several of the very common casinos, like Golden Online Casino, which hands out a pay out of up to 95 per cent!

Hence, in essence, the slot machine takes all the dough played into it and pays it out to a few privileged winners. The casino only gets to keep a generally tiny per cent of all the odds allocated.

The casino one armed bandit software controls each part of the machine, from the flickering lights to the rolling of the reels.

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