Modern casino Slots are controlled by computer chips and software, and the win %s are preprogrammed into the software.
Casino one armed bandits have Random # Generators which are ceaselessly generating combinations, even when the slot machine game is not active.
Running in sync with the random # generator of the casino one-armed bandit is the payout percentage.
The payout per cent controls how much the one-armed bandit will payout, for eg the pay out percent could be ninety per cent, which means the slot machine will pay ninety per cent of all the bets played, and the casino will then get to keep ten percent.
This really does not mean that every time you bet ten credits you will receive 9 in return – where is the fun … exhilaration in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly fire up a hot streak and you might draw the big grand prize.
The pay off %s will vary between the differing games and several of the very common casinos, for example Golden Online Casino, which offers a pay out rate of up to ninety five percent!
Hence, in essence, the one-armed bandit takes all the cash played into it and pays it out to a few privileged winners. The casino only gets to keep a relatively low % of all the wagers allotted.
The casino one armed bandit software controls every part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is developed by the RNG which is linked to the pictures on the reel.
