Modern casino slot machine games are controlled by a computer, and the win percentages are preprogrammed into the computer software.
Casino one armed bandits have Random # Generators which are continually generating combos, even when the slot machine game is not currently being played.
Running jointly with the Random Number Generator of the casino one-armed bandit is the pay out rate per cent.
The payout percentage controls just how much the one-armed bandit will pay out, for e.g. the payout % might be ninety percent, meaning the slot machine will payout ninety percent of all the bets played, … the casino will then get to keep 10%.
This doesn’t mean that each and every time you bet 10 credits you will receive nine in return – where is the fun … excitement in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly fire up a hot streak and you might draw the big jackpot.
The pay off %s will very likely vary between the different games and some of the notably famous casinos, e.g. Golden Online Casino, which hands out a pay out of up to ninety five percentage!
This means that, in essence, the one-armed bandit takes all the cash played into it and pays it out to a number of chosen winners. The casino only gets to keep a averagely small percentage of all the gambles made.
The casino slot software controls any part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which associates with the pictures on the reel.
