Modern casino slot machines are controlled by a computer, and the winning percentages are preprogrammed into the computer software.
Casino slot games have RNGs that are eternally generating combinations, even when the machine is not being played.
Running simultaneously with the RNG of the casino slot machine game is the payout percent.
The pay out % controls just how much the one-armed bandit will pay out, for eg the payout per cent might be ninety percent, which means the slot machine game will payout ninety per cent of all the bets played, … the casino only gets to keep 10 per cent.
This really does not mean that each time you bet 10 credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine will not payout for a little while, and then suddenly jump on a hot streak and you might draw the big pot prize.
The pay out %s will very likely vary between the different games and a handful of the very established casinos, for e.g Golden Online Casino, which tenders a pay out rate of up to 95 %!
This means that, in essence, the slot machine takes all the dough played into it and pays it out to several fortunate winners. The casino only gets to keep a generally petite percent of all the wagers put out.
The casino one armed bandit software controls any part of the machine, from the flickering lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which relates to the pictures on the reel.
