Modern casino slot machine games are controlled by computer chips and software, and the win %s are preprogrammed into the gaming software.
Casino slot games have RNGs which are endlessly generating combos, even when the machine is not being played.
Running jointly with the Random Number Generator of the casino slot machine game is the payout rate %.
The payout % controls just how much the slot machine will payout, for example the payout percent may be 90%, meaning the slot machine will pay out ninety per cent of all the wagers played, and the casino will then get to keep ten per cent.
This is not to say that every time you bet 10 credits you will receive nine in return – where’s the fun and thrill in that? Instead, the casino slot just won’t pay out for a while, and then suddenly start up a hot streak and you might catch the big jackpot.
The pay off %s will definitely vary between the differing games and a handful of the highly common casinos, for example Golden Online Casino, which puts forth a payment of up to 95 %!
As a result, in essence, the one-armed bandit takes all the dough played into it and pays it out to a few fortunate winners. The casino only gets to keep a relatively minute per cent of all the gambles put out.
The casino slot software controls every part of the machine, from the flashing lights to the revolving of the reels.
When you hit spin on the one-armed bandit, a combination is generated by the RNG which associates with the pictures on the reel.
