Modern casino slot machines are controlled by computer chips and software, and the win %s are preprogrammed into the computer software.
Casino slot machine games have RNGs which are continually generating combos, even when the slot machine is not being played.
Running in sync with the Random Number Generator of the casino slot machine game is the pay out per cent.
The pay out per cent controls how much the one-armed bandit will pay, for example the payout % may be ninety per cent, which means the one arm bandit will payout 90% of all the wagers played, and the casino will then get to keep ten percent.
This really does not mean that each time you bet ten credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine game will not pay out for a bit, and then suddenly hit a hot streak and you might draw the big jackpot prize.
The pay off %s shall vary between the alternate games and some of the extremely popular casinos, for instance Golden Online Casino, which tenders a payout of up to 95 %!
This means that, in essence, the slot machine game takes all the currency played into it and pays it out to a handful of lucky winners. The casino only gets to keep a relatively small percentage of all the bets allocated.
The casino one armed bandit software controls every part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
