Modern casino slot machines are controlled by computer chips and software, and the win %s are pre-programmed into the game software.
Casino slot games have RNGs which are endlessly generating combinations, even when the slot machine game is not currently being played.
Running jointly with the random # generator of the casino slot machine game is the payout %.
The payout % controls just how much the slot machine will pay, for example the payout % might be ninety percent, which means the slot game will pay ninety per cent of all the bets played, … the casino only gets to keep ten percent.
This does not imply that for every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino slot machine just will not pay out for a while, and then suddenly start up a hot streak and you might hit a big pot prize.
The payoff percentages will tend to vary between the a variety of games and several of the highly famous casinos, for e.g Golden Online Casino, which offers a pay out of up to 95 per cent!
Thus, in essence, the one-armed bandit takes all the currency played into it and pays it out to several lucky winners. The casino only gets to keep a averagely petite per cent of all the stakes allotted.
The casino slot software controls each part of the machine, from the flickering lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is developed by the RNG which corresponds to the pictures on the reel.
