Modern casino Slots are controlled by computer software, and the winning percentages are pre-programmed into the gaming software.
Casino slot machines have Random Number Generators that are constantly generating combinations, even when the slot machine game is not currently being played.
Running synchronously with the RNG of the casino slot machine is the pay out percentage.
The pay out % controls just how much the one-armed bandit will payout, for example the payout % might be ninety per cent, which means the slot machine will pay ninety per cent of all the wagers played, and the casino only gets to keep 10%.
This really does not mean that for every time you bet 10 credits you will receive nine in return – where’s the fun … thrill in that? Instead, the casino slot machine game just will not pay out for a bit, and then suddenly hit a hot streak and you might draw the big jackpot prize.
The pay off %s will vary between the various games and some of the highly acclaimed casinos, e.g. Golden Online Casino, which puts forth a pay out rate of up to 95 %!
This means that, in essence, the one-armed bandit takes all the cash played into it and pays it out to several chosen winners. The casino only gets to keep a averagely indistinct % of all the odds allotted.
The casino one armed bandit software controls every part of the machine, from the blinking lights to the turning of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which connects with the pictures on the reel.
