Modern casino Slots are controlled by computer chips and software, and the winner %s are preprogrammed into the software.
Casino one armed bandits have Random # Generators that are ceaselessly generating combinations, even when the slot machine is not being played.
Running in sync with the Random Number Generator of the casino one-armed bandit is the payout per cent.
The payout percent controls just how much the slot machine will pay out, for eg the payout % could be 90%, meaning the slot game will payout ninety per cent of all the bets played, … the casino only gets to keep ten per cent.
This is not to say that every time you bet ten credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot machine game won’t payout for a while, and then suddenly fire up a hot streak and you might draw the big grand prize.
The payout percentages most likely will vary between the different games and just a few of the highly established casinos, e.g. Golden Online Casino, which gives a payout of up to ninety-five percent!
Thus, in essence, the slot machine game takes all the currency played into it and pays it out to some chosen winners. The casino only gets to keep a fairly tiny per cent of all the gambles allotted.
The casino slot software controls each and every part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is generated by the RNG which connects with the pictures on the reel.
