Modern casino one armed bandits are controlled by computer chips and software, and the winner percentages are pre-programmed into the gaming software.
Casino Slots have RNGs which are constantly generating combinations, even when the slot machine game is not being played.
Running jointly with the random # generator of the casino one-armed bandit is the pay out percentage.
The pay out percent controls how much the one-armed bandit will payout, for e.g. the pay per cent could be 90%, meaning the slot machine will payout 90% of all the wagers played, … the casino will then get to keep 10 percent.
This really does not mean 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 slot will not pay out for a bit, and then suddenly hit a hot streak and you might catch the big top prize.
The profit percentages will most likely vary between the various games and a couple of the very established casinos, for e.g Golden Online Casino, which provides a payout rate of up to ninety five percentage!
Therefore, in essence, the one-armed bandit takes all the money played into it and pays it out to some privileged winners. The casino only gets to keep a averagely indistinct per cent of all the plays made.
The casino slot software controls each part of the machine, from the flashing lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which relates to the pictures on the reel.
