Modern casino slot machine games are controlled by computer software, and the winning percentages are pre-programmed into the gaming software.
Casino slot machine games have Random Number Generators that are continually generating combos, even when the machine is not being played.
Running collectively with the random # generator of the casino one-armed bandit is the payout rate per cent.
The pay out percentage controls just how much the one-armed bandit will pay out, for e.g. the pay percentage might be ninety percent, which means the slot machine game will pay out ninety per cent of all the bets played, and the casino simply gets to keep 10 percent.
This is not to say that every time you bet 10 credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine game just will not pay out for a little while, and then suddenly jump on a hot streak and you might hit a big jackpot prize.
The pay off percentages will definitely vary between the differing games and some of the very established casinos, such as Golden Online Casino, which gives a pay out rate of up to 95 per cent!
Hence, in essence, the one-armed bandit takes all the dough played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a fairly minute per cent of all the bets put out.
The casino slot software controls any part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which relates to the pictures on the reel.
