Modern casino slot games are controlled by a computer, and the win %s are preprogrammed into the gaming software.

Casino slot games have Random Number Generators that are eternally generating combinations, even when the game is not being played.

Running collectively with the random # generator of the casino one-armed bandit is the pay out percentage.

The payout % controls how much the one-armed bandit will pay out, for e.g. the pay out per cent might be 90%, meaning the one arm bandit will payout ninety per cent of all the wagers played, … the casino simply gets to keep 10 percent.

This really does not mean that for every time you bet 10 credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine game won’t pay out for a bit, and then suddenly go on a hot streak and you might catch the big jackpot prize.

The pay out %s will very likely vary between the a variety of games and a few of the very established casinos, such as Golden Online Casino, which tenders a pay out of up to 95 per cent!

This means that, in essence, the slot machine takes all the money played into it and pays it out to some fortunate winners. The casino only gets to keep a generally small percent of all the bets allotted.

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

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