Modern casino slot machine games are controlled by computer chips and software, and the winner percentages are preprogrammed into the game software.
Casino Slots have Random # Generators which are continuously generating combinations, even when the game is not currently being played.
Running side by side with the RNG of the casino slot machine game is the pay out per cent.
The payout % controls just how much the slot machine will pay out, for e.g. the pay out per cent may be ninety percent, meaning the slot machine will payout ninety per cent of all the bets played, … the casino will then get to keep ten per cent.
This doesn’t mean that every time you bet 10 credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine will not payout for a little while, and then suddenly hit a hot streak and you might draw the big pot prize.
The payoff %s most likely will vary between the various games and some of the notably favored casinos, for example Golden Online Casino, which hands out a payout rate of up to 95 percent!
So, in essence, the one-armed bandit takes all the funds played into it and pays it out to a couple of lucky winners. The casino only gets to keep a averagely indistinct percentage of all the odds put out.
The casino slot machine software controls every single part of the machine, from the flashing lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
