Modern casino slot games are controlled by computer chips and software, and the winner %s are preprogrammed into the game software.
Casino slot machine games have RNGs which are endlessly generating combinations, even when the machine is not active.
Running concurrently with the random # generator of the casino slot machine is the payout %.
The payout % controls just how much the slot machine game will payout, for e.g. the payout percentage might be 90%, meaning the slot machine game will pay ninety percent of all the bets played, … the casino simply gets to keep ten per cent.
This does not mean that for every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot just won’t pay out for a little while, and then suddenly go on a hot streak and you might catch the big jackpot prize.
The pay off percentages will most likely vary between the differing games and a few of the highly established casinos, for e.g Golden Online Casino, which tenders a pay out rate of up to ninety five percentage!
Thus, in essence, the slot machine game takes all the funds played into it and pays it out to several fortunate winners. The casino only gets to keep a fairly tiny percentage of all the odds made.
The casino slot machine software controls every single part of the machine, from the dazzling lights to the circulating of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which corresponds to the pictures on the reel.
