Modern casino slot machines are controlled by computer chips and software, and the winner percentages are preprogrammed into the software.
Casino slot machine games have RNGs which are eternally generating combinations, even when the machine is not currently being played.
Running in unison with the RNG of the casino slot machine is the payout per cent.
The payout per cent controls how much the slot machine will pay, for example the pay percentage might be ninety per cent, meaning the one arm bandit will payout ninety percent of all the wagers played, and the casino only gets to keep ten per cent.
This does not mean that each and every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino one arm bandit will not pay out for a bit, and then suddenly jump on a hot streak and you might catch the big jackpot prize.
The pay out percentages most likely will vary between the differing games and a handful of the very common casinos, like Golden Online Casino, which offers a payout of up to ninety-five %!
This means that, in essence, the one-armed bandit takes all the dough played into it and pays it out to a handful of lucky winners. The casino only gets to keep a averagely low % of all the bets put out.
The casino one armed bandit software controls each part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which associates with the pictures on the reel.
