Modern casino one armed bandits are controlled by computer software, and the winner percentages are preprogrammed into the game software.

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

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

The payout percent controls just how much the one-armed bandit will pay out, for e.g. the pay percentage could be ninety per cent, meaning the slot machine game will pay 90% of all the bets played, … the casino simply gets to keep 10%.

This does not mean that each time you bet 10 credits you will receive nine in return – where’s the fun and excitement in that? Instead, the casino one arm bandit just won’t pay out for a while, and then suddenly start up a hot streak and you might hit a big pot prize.

The pay off %s will tend to vary between the differing games and just a few of the notably famous casinos, for example Golden Online Casino, which offers a payment of up to ninety-five per cent!

Hence, in essence, the slot machine game takes all the funds played into it and pays it out to a few privileged winners. The casino only gets to keep a basically indistinct % of all the stakes allotted.

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

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