Modern casino slot machines are controlled by computer chips and software, and the win %s are preprogrammed into the software.
Casino slot games have Random # Generators which are continuously generating combos, even when the machine is not being played.
Running in unison with the random # generator of the casino one-armed bandit is the payout percent.
The payout percent controls just how much the slot machine game will pay, for eg the pay percent could be ninety per cent, meaning the one arm bandit will pay 90% of all the stakes played, and the casino gets to keep ten percent.
This is not to say that each and every time you bet ten credits you will receive nine in return – where is the fun … thrill in that? Instead, the casino slot just won’t pay out for a little while, and then suddenly hit a hot streak and you might catch the big jackpot prize.
The profit %s will vary between the various games and a handful of the notably favored casinos, like Golden Online Casino, which puts forth a pay out of up to 95 %!
As a result, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a basically low % of all the stakes placed.
The casino slot software controls any part of the machine, from the blinking lights to the rotating 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.
