Modern casino slot games are controlled by computer chips and software, and the win percentages are preprogrammed into the gaming software.

Casino one armed bandits have Random Number Generators that are continually generating combos, even when the slot machine game is not currently being played.

Running in unison with the RNG of the casino slot machine game is the payout percentage.

The payout per cent controls how much the slot machine will pay out, for e.g. the payout percentage may be 90%, which means the slot game will pay ninety per cent of all the bets played, and the casino will then get to keep ten percent.

This doesn’t imply that every time you bet 10 credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino one arm bandit won’t payout for a while, and then suddenly go on a hot streak and you might hit a big jackpot prize.

The payoff %s will tend to vary between the differing games and just a few of the highly popular casinos, for instance Golden Online Casino, which gives a payout rate of up to ninety five per cent!

Thus, in essence, the slot machine game takes all the funds played into it and pays it out to a number of chosen winners. The casino only gets to keep a relatively small percent of all the wagers allocated.

The casino one armed bandit software controls every single part of the machine, from the blinking lights to the rotating of the reels.

When you hit spin on the one-armed bandit, a combination is developed by the RNG which relates to the pictures on the reel.
