Modern casino one armed bandits are controlled by a computer, and the win %s are pre-programmed into the game software.
Casino slot machine games have Random Number Generators that are constantly generating combinations, even when the game is not currently being played.
Running in sync with the random # generator of the casino slot machine game is the pay out rate percent.
The pay out percentage controls just how much the slot machine game will pay out, for e.g. the payout % could be ninety per cent, which means the one arm bandit will pay out ninety per cent of all the wagers played, and the casino gets to keep 10 per cent.
This really does not mean that each time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino one arm bandit won’t payout for a little while, and then suddenly fire up a hot streak and you might draw the big top prize.
The pay out %s will most likely vary between the differing games and several of the highly acclaimed casinos, for instance Golden Online Casino, which provides a pay out rate of up to ninety-five percent!
Thus, in essence, the one-armed bandit takes all the dough played into it and pays it out to a number of privileged winners. The casino only gets to keep a considerably low per cent of all the plays placed.
The casino slot machine software controls any part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the one-armed bandit, a combination is developed by the RNG which associates with the pictures on the reel.
