Modern casino one armed bandits are controlled by a computer, and the winner percentages are preprogrammed into the gaming software.
Casino slot games have Random # Generators that are eternally generating combinations, even when the machine is not currently being played.
Running synchronously with the RNG of the casino one-armed bandit is the pay out percent.
The pay out percentage controls just how much the slot machine game will pay, for example the payout percent might be ninety per cent, meaning the slot machine will pay ninety percent of all the bets played, and the casino simply gets to keep ten percent.
This does not mean that for every time you bet ten credits you will receive nine in return – where’s the fun and exhilaration in that? Instead, the casino slot machine will not pay out for a little while, and then suddenly go on a hot streak and you might hit a big pot prize.
The pay off percentages will vary between the differing games and a few of the very acclaimed casinos, e.g. Golden Online Casino, which gives a pay out 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 couple of chosen winners. The casino only gets to keep a fairly petite percent of all the gambles made.
The casino slot software controls every single part of the machine, from the blinking lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
