Modern casino slot machines are controlled by computer software, and the winning %s are preprogrammed into the software.
Casino one armed bandits have Random Number Generators that are ceaselessly generating combinations, even when the machine is not currently being played.
Running side by side with the random # generator of the casino slot machine is the payout %.
The payout percent controls just how much the slot machine will payout, for e.g. the pay out percentage might be ninety percent, meaning the slot machine game will pay out 90% of all the bets played, … the casino will then get to keep 10 per cent.
This really does not mean that each time you bet ten credits you will receive 9 in return – where is the fun and fascination in that? Instead, the casino slot machine game will not payout for a while, and then suddenly start up a hot streak and you might catch the big top prize.
The pay off %s will most likely vary between the different games and a few of the notably famous casinos, such as Golden Online Casino, which provides a payout of up to ninety five %!
Thus, in essence, the slot machine takes all the funds played into it and pays it out to some fortunate winners. The casino only gets to keep a generally petite percentage of all the bets made.
The casino slot software controls each 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 connects with the pictures on the reel.
