Modern casino slot machines are controlled by a computer, and the win %s are preprogrammed into the computer software.
Casino one armed bandits have Random Number Generators that are continually generating combinations, even when the game is not currently being played.
Running in sync with the RNG of the casino slot machine is the pay out rate percentage.
The payout per cent controls how much the slot machine will pay out, for example the pay % may be 90%, meaning the one arm bandit will payout ninety percent of all the stakes played, and the casino will then get to keep 10 per cent.
This doesn’t mean that each and every time you bet ten credits you will receive nine in return – where’s the fun … exhilaration in that? Instead, the casino one arm bandit just won’t pay out for a bit, and then suddenly jump on a hot streak and you might hit a big jackpot.
The pay off percentages will vary between the assorted games and a handful of the highly common casinos, for example Golden Online Casino, which offers a pay out of up to ninety five percentage!
So, in essence, the slot machine game takes all the funds played into it and pays it out to several chosen winners. The casino only gets to keep a relatively small per cent of all the bets made.
The casino one armed bandit software controls each part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the one-armed bandit, a combination is produced by the RNG which corresponds to the pictures on the reel.
