Modern casino slot games are controlled by computer chips and software, and the winning percentages are preprogrammed into the computer software.
Casino Slots have Random Number Generators that are continuously generating combos, even when the machine is not being played.
Running side by side with the Random Number Generator of the casino one-armed bandit is the pay out %.
The payout percentage controls how much the slot machine game will pay, for example the pay out percent may be 90%, which means the slot machine will pay ninety per cent of all the stakes played, and the casino gets to keep 10%.
This is not to say that for every time you bet ten credits you will receive 9 in return – where is the fun and exhilaration in that? Instead, the casino one arm bandit won’t payout for a little while, and then suddenly hit a hot streak and you might draw the big top prize.
The pay off percentages will tend to vary between the different games and just a few of the most established casinos, e.g. Golden Online Casino, which hands out a payout rate of up to 95 %!
Thus, 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 considerably small percentage of all the plays placed.
The casino one armed bandit software controls each and every part of the machine, from the flashing lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which connects with the pictures on the reel.
