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

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

Running side by side with the random # generator of the casino slot machine is the pay out %.

The pay out per cent controls how much the slot machine will pay, for example the payout percent may be 90%, meaning the one arm bandit will pay out ninety percent of all the stakes played, and the casino simply gets to keep 10 per cent.

This doesn’t mean that each time you bet ten credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino slot won’t pay out for a bit, and then suddenly jump on a hot streak and you might draw the big jackpot.

The profit percentages will tend to vary between the a variety of games and a handful of the very famous casinos, for example Golden Online Casino, which tenders a pay out of up to ninety five per cent!

Hence, in essence, the one-armed bandit takes all the money played into it and pays it out to a couple of privileged winners. The casino only gets to keep a fairly petite percent of all the wagers placed.

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

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