Modern casino slot machines are controlled by a computer, and the winning percentages are preprogrammed into the computer software.
Casino slot games have Random Number Generators that are constantly generating combinations, even when the slot machine is not being played.
Running side by side with the Random Number Generator of the casino one-armed bandit is the pay out rate %.
The payout percentage controls just how much the slot machine game will pay out, for e.g. the payout percent may be ninety percent, which means the slot machine will pay 90% of all the stakes played, … the casino will then get to keep 10 percent.
This does not imply that each and every time you bet 10 credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino one arm bandit will not payout for a little while, and then suddenly jump on a hot streak and you might hit a big jackpot.
The payout percentages will definitely vary between the different games and a couple of the extremely favored casinos, for example Golden Online Casino, which gives a cash payment of up to ninety-five per cent!
Hence, in essence, the one-armed bandit takes all the currency played into it and pays it out to a number of fortunate winners. The casino only gets to keep a considerably small per cent of all the plays made.
The casino slot software controls any 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 generated by the RNG which corresponds to the pictures on the reel.
