Modern casino slot machine games are controlled by computer software, and the win %s are pre-programmed into the gaming software.
Casino one armed bandits have RNGs which are constantly generating combos, even when the slot machine is not currently being played.
Running simultaneously with the random # generator of the casino slot machine is the pay out rate per cent.
The payout % controls just how much the slot machine will pay, for eg the pay percent might be 90%, which means the slot machine will pay out ninety per cent of all the bets played, and the casino only gets to keep 10 percent.
This really does not mean that for every 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 little while, and then suddenly fire up a hot streak and you might draw the big top prize.
The pay out %s will vary between the various games and several of the most favored casinos, like Golden Online Casino, which hands out a payout of up to 95 %!
So, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a few fortunate winners. The casino only gets to keep a averagely tiny % of all the odds put out.
The casino slot machine software controls every single part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the one-armed bandit, a combination is generated by the RNG which relates to the pictures on the reel.
