Modern casino Slots are controlled by computer software, and the winner %s are preprogrammed into the software.
Casino Slots have Random # Generators that are continuously generating combinations, even when the game is not active.
Running simultaneously with the random # generator of the casino slot machine is the pay out rate percent.
The pay out percentage controls just how much the slot machine will pay, for e.g. the pay out % might be ninety percent, meaning the slot game will payout 90% of all the bets played, and the casino will then get to keep 10 per cent.
This really does not mean that for every time you bet 10 credits you will receive 9 in return – where’s the fun … exhilaration in that? Instead, the casino slot machine game won’t payout for a bit, and then suddenly go on a hot streak and you might draw the big jackpot prize.
The pay off %s will definitely vary between the differing games and a handful of the extremely common casinos, for instance Golden Online Casino, which provides a pay out of up to 95 %!
So, in essence, the one-armed bandit takes all the cash played into it and pays it out to a few chosen winners. The casino only gets to keep a relatively minute % of all the bets allotted.
The casino one armed bandit software controls each part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which corresponds to the pictures on the reel.
