Modern casino Slots are controlled by computer chips and software, and the win percentages are pre-programmed into the software.
Casino slot machine games have Random # Generators which are eternally generating combinations, even when the game is not active.
Running side by side with the random # generator of the casino slot machine is the pay out %.
The pay out per cent controls how much the one-armed bandit will payout, for e.g. the pay percent could be ninety percent, meaning the one arm bandit will pay out 90% of all the stakes played, and the casino only gets to keep 10%.
This doesn’t imply that for every time you bet 10 credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino one arm bandit just will not payout for a bit, and then suddenly hit a hot streak and you might draw the big pot prize.
The payout %s will definitely vary between the various games and some of the extremely popular casinos, for e.g Golden Online Casino, which gives a payout rate of up to ninety-five percent!
So, in essence, the slot machine game takes all the currency played into it and pays it out to several lucky winners. The casino only gets to keep a considerably tiny percentage of all the bets allotted.
The casino one armed bandit software controls any part of the machine, from the flickering lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which corresponds to the pictures on the reel.
