Modern casino slot machines are controlled by computer chips and software, and the win percentages are pre-programmed into the gaming software.

Casino slot machine games have Random # Generators which are endlessly generating combinations, even when the machine is not active.

Running jointly with the random # generator of the casino slot machine is the payout percent.

The payout percent controls just how much the slot machine game will payout, for e.g. the pay out per cent may be 90%, which means the slot machine game will payout ninety per cent of all the stakes played, … the casino simply gets to keep ten per cent.

This is not to say that each time you bet 10 credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine game just won’t pay out for a bit, and then suddenly start up a hot streak and you might catch the big jackpot prize.

The pay off %s will definitely vary between the differing games and some of the most acclaimed casinos, e.g. Golden Online Casino, which provides a payout of up to ninety-five %!

As a result, in essence, the one-armed bandit takes all the funds played into it and pays it out to a few privileged winners. The casino only gets to keep a generally indistinct percent of all the wagers put out.

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

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