Modern casino slot machines are controlled by computer chips and software, and the winning %s are preprogrammed into the gaming software.
Casino one armed bandits have RNGs that are continuously generating combinations, even when the game is not active.
Running side by side with the random # generator of the casino slot machine is the payout percent.
The payout per cent controls how much the slot machine will pay out, for e.g. the payout percent could be ninety percent, which means the slot machine will payout 90% of all the stakes played, … the casino gets to keep 10 percent.
This is not to say that each and every time you bet ten credits you will receive 9 in return – where is the fun and excitement in that? Instead, the casino one arm bandit just won’t pay out for a bit, and then suddenly hit a hot streak and you might draw the big pot prize.
The pay off percentages usually will vary between the various games and a few of the most established casinos, for example Golden Online Casino, which provides a payout of up to ninety five %!
So, in essence, the one-armed bandit takes all the funds played into it and pays it out to a few lucky winners. The casino only gets to keep a considerably minute percentage of all the stakes 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, a combination is formed by the RNG which relates to the pictures on the reel.
