Modern casino slot machines are controlled by computer software, and the winner percentages are preprogrammed into the game software.
Casino slot games have Random # Generators that are constantly generating combos, even when the machine is not being played.
Running in sync with the random # generator of the casino one-armed bandit is the pay out rate percent.
The payout per cent controls how much the slot machine game will pay out, for example the pay out percentage could be 90%, meaning the slot game will pay out ninety percent of all the bets played, and the casino will then get to keep ten percent.
This does not mean that every time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot just will not payout for a while, and then suddenly start up a hot streak and you might catch the big top prize.
The profit percentages will most likely vary between the differing games and just a few of the highly famous casinos, for instance Golden Online Casino, which gives a payment of up to 95 %!
So, in essence, the slot machine takes all the dough played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a averagely low percent of all the stakes put out.
The casino slot software controls any 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 produced by the RNG which corresponds to the pictures on the reel.
