Modern casino slot machine games are controlled by a computer, and the win %s are pre-programmed into the computer software.

Casino one armed bandits have Random Number Generators which are continually generating combinations, even when the game is not active.

Running synchronously with the random # generator of the casino slot machine game is the payout rate percent.

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

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

The payoff %s usually will vary between the alternate games and some of the extremely popular casinos, e.g. Golden Online Casino, which hands out a payment of up to ninety-five percent!

As a result, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to some privileged winners. The casino only gets to keep a relatively low % of all the gambles put out.

The casino slot machine software controls each part of the machine, from the dazzling lights to the spinning of the reels.

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