Modern casino slot machines are controlled by computer chips and software, and the winner percentages are pre-programmed into the gaming software.
Casino slot games have RNGs that are endlessly generating combinations, even when the game is not being played.
Running collectively with the RNG of the casino one-armed bandit is the pay out rate percentage.
The payout percent controls just how much the one-armed bandit will payout, for eg the pay % could be 90%, meaning the slot machine will pay 90% of all the bets played, and the casino will then get to keep 10 per cent.
This does not imply that for every time you bet 10 credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine just won’t pay out for a bit, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The payout percentages will tend to vary between the a variety of games and just a few of the most popular casinos, e.g. Golden Online Casino, which provides a cash payment of up to 95 percent!
So, in essence, the slot machine game takes all the money played into it and pays it out to a number of chosen winners. The casino only gets to keep a considerably indistinct percentage of all the bets made.
The casino slot machine software controls every single part of the machine, from the blinking lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which relates to the pictures on the reel.
