Modern casino slot machine games are controlled by a computer, and the winner percentages are preprogrammed into the gaming software.
Casino one armed bandits have Random Number Generators that are endlessly generating combinations, even when the slot machine is not active.
Running side by side with the random # generator of the casino one-armed bandit is the payout percentage.
The payout per cent controls just how much the slot machine will pay out, for example the payout per cent might be 90%, which means the slot machine game will pay out 90% of all the wagers played, … the casino will then get to keep 10 percent.
This doesn’t mean that each time you bet ten credits you will receive 9 in return – where is the fun … exhilaration in that? Instead, the casino slot won’t pay out for a bit, and then suddenly start up a hot streak and you might hit a big grand prize.
The profit percentages will tend to vary between the differing games and some of the extremely established casinos, like Golden Online Casino, which gives a payment of up to ninety five per cent!
As a result, in essence, the slot machine takes all the cash played into it and pays it out to a few lucky winners. The casino only gets to keep a fairly tiny percent of all the wagers made.
The casino slot software controls each and every part of the machine, from the blinking lights to the circulating of the reels.
When you hit spin on the slot machine game, a combination is set up by the RNG which relates to the pictures on the reel.
