Modern casino slot machine games are controlled by computer chips and software, and the winning %s are preprogrammed into the game software.
Casino slot machine games have Random # Generators which are continually generating combinations, even when the slot machine is not currently being played.
Running in unison with the random # generator of the casino slot machine is the payout rate percent.
The payout per cent controls how much the slot machine game will payout, for e.g. the pay percentage could be 90%, which means the one arm bandit will payout ninety per cent of all the stakes played, and the casino gets to keep ten per cent.
This is not to say that each and every time you bet 10 credits you will receive nine in return – where’s the fun … exhilaration in that? Instead, the casino slot machine game won’t payout for a little while, and then suddenly start up a hot streak and you might catch the big pot prize.
The pay off percentages usually will vary between the a variety of games and just a few of the notably common casinos, for example Golden Online Casino, which tenders a payout of up to ninety five percentage!
So, in essence, the one-armed bandit takes all the cash played into it and pays it out to a couple of lucky winners. The casino only gets to keep a relatively tiny per cent of all the plays placed.
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 generated by the RNG which relates to the pictures on the reel.
