Modern casino one armed bandits are controlled by computer software, and the winning %s are preprogrammed into the game software.
Casino slot machines have RNGs that are constantly generating combos, even when the slot machine is not being played.
Running simultaneously with the Random Number Generator of the casino slot machine game is the pay out per cent.
The payout per cent controls just how much the slot machine will pay, for example the pay out percentage may be ninety per cent, meaning the slot machine game will payout ninety per cent of all the bets played, … the casino will then get to keep 10%.
This doesn’t mean that each time you bet 10 credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino one arm bandit will not pay out for a while, and then suddenly go on a hot streak and you might catch the big pot prize.
The pay out percentages most likely will vary between the various games and a few of the very favored casinos, for example Golden Online Casino, which offers a pay out rate of up to ninety five per cent!
This means that, in essence, the slot machine takes all the money played into it and pays it out to a handful of privileged winners. The casino only gets to keep a basically low percentage of all the stakes put out.
The casino one armed bandit software controls every part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the one-armed bandit, a combination is developed by the RNG which relates to the pictures on the reel.
