Modern casino slot machines are controlled by computer software, and the win percentages are preprogrammed into the software.
Casino slot games have Random Number Generators that are ceaselessly generating combinations, even when the machine is not being played.
Running side by side with the random # generator of the casino slot machine game is the payout rate percent.
The payout per cent controls just how much the one-armed bandit will pay, for example the pay out percent could be ninety percent, meaning the slot machine game will pay out ninety per cent of all the bets played, and the casino simply gets to keep 10%.
This does not imply that every time you bet ten credits you will receive 9 in return – where’s the fun … exhilaration in that? Instead, the casino slot machine will not pay out for a little while, and then suddenly hit a hot streak and you might catch the big jackpot.
The profit percentages usually will vary between the a variety of games and just a few of the very famous casinos, e.g. Golden Online Casino, which provides a payment of up to 95 percent!
This means that, in essence, the slot machine takes all the $$$$$ played into it and pays it out to some fortunate winners. The casino only gets to keep a basically minute per cent of all the plays put out.
The casino slot 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 corresponds to the pictures on the reel.
