Modern casino slot games are controlled by computer software, and the winner percentages are preprogrammed into the computer software.
Casino Slots have RNGs that are eternally generating combinations, even when the slot machine game is not active.
Running side by side with the random # generator of the casino one-armed bandit is the payout rate %.
The payout percent controls just how much the slot machine game will pay, for e.g. the payout percentage might be ninety per cent, which means the one arm bandit will pay out ninety percent of all the stakes played, and the casino simply gets to keep 10%.
This does not 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 machine game won’t payout for a bit, and then suddenly go on a hot streak and you might draw the big top prize.
The pay out percentages will very likely vary between the a variety of games and some of the notably popular casinos, for example Golden Online Casino, which puts forth a cash payment of up to 95 percent!
Thus, in essence, the slot machine takes all the currency played into it and pays it out to a few privileged winners. The casino only gets to keep a fairly petite percentage of all the gambles made.
The casino slot machine software controls each part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which associates with the pictures on the reel.
