Modern casino slot games are controlled by a computer, and the win %s are preprogrammed into the software.
Casino slot machine games have RNGs which are eternally generating combinations, even when the slot machine game is not active.
Running simultaneously with the Random Number Generator of the casino one-armed bandit is the payout percent.
The payout percentage controls how much the slot machine will pay out, for eg the pay percent may be ninety per cent, meaning the one arm bandit will pay out ninety per cent of all the wagers played, … the casino will then get to keep 10%.
This really does not mean that every time you bet 10 credits you will receive 9 in return – where’s the fun and excitement in that? Instead, the casino one arm bandit will not pay out for a bit, and then suddenly go on a hot streak and you might draw the big top prize.
The profit percentages will very likely vary between the different games and some of the notably common casinos, for e.g Golden Online Casino, which offers a payout rate of up to ninety-five %!
This means that, in essence, the one-armed bandit takes all the money played into it and pays it out to a handful of privileged winners. The casino only gets to keep a fairly tiny percentage of all the bets allotted.
The casino one armed bandit software controls any part of the machine, from the dazzling lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which corresponds to the pictures on the reel.
