Modern casino slot machines are controlled by computer chips and software, and the winner %s are pre-programmed into the computer software.
Casino Slots have Random Number Generators that are eternally generating combinations, even when the machine is not currently being played.
Running simultaneously with the random # generator of the casino slot machine is the pay out rate percent.
The pay out percent controls just how much the one-armed bandit will payout, for e.g. the pay percent might be ninety percent, which means the slot game will pay 90% of all the bets played, … the casino only gets to keep ten percent.
This is not to say that each time you bet 10 credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine just will not payout for a while, and then suddenly fire up a hot streak and you might catch the big pot prize.
The payout percentages will very likely vary between the various games and a handful of the extremely acclaimed casinos, such as Golden Online Casino, which offers a payout rate of up to ninety five per cent!
This means that, in essence, the slot machine takes all the dough played into it and pays it out to some privileged winners. The casino only gets to keep a generally minute per cent of all the stakes put out.
The casino slot machine software controls any part of the machine, from the blinking lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which relates to the pictures on the reel.
