Modern casino Slots are controlled by computer chips and software, and the win %s are pre-programmed into the gaming software.
Casino Slots have Random # Generators that are eternally generating combos, even when the slot machine game is not currently being played.
Running simultaneously with the random # generator of the casino slot machine is the pay out rate percent.
The payout percentage controls just how much the one-armed bandit will pay, for e.g. the pay out per cent could be ninety per cent, which means the slot game will pay ninety percent of all the stakes played, … the casino only gets to keep 10 percent.
This doesn’t imply that for every time you bet 10 credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino slot won’t pay out for a little while, and then suddenly hit a hot streak and you might draw the big grand prize.
The payoff percentages will definitely vary between the various games and a couple of the very established casinos, for e.g Golden Online Casino, which provides a pay out of up to 95 %!
Therefore, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to several lucky winners. The casino only gets to keep a basically tiny per cent of all the plays allotted.
The casino slot machine software controls every part of the machine, from the flickering lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which associates with the pictures on the reel.
