Modern casino slot machines are controlled by computer chips and software, and the winning %s are preprogrammed into the gaming software.
Casino one armed bandits have Random Number Generators which are continually generating combos, even when the slot machine is not active.
Running synchronously 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 slot machine game will pay, for e.g. the pay out per cent may be 90%, meaning the one arm bandit will payout ninety per cent of all the wagers played, and the casino will then get to keep ten percent.
This really does not mean that every time you bet ten credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit just will not pay out for a while, and then suddenly jump on a hot streak and you might hit a big top prize.
The pay off percentages will tend to vary between the differing games and some of the highly famous casinos, for e.g Golden Online Casino, which provides a cash payment of up to ninety five percent!
So, in essence, the one-armed bandit takes all the currency played into it and pays it out to a handful of privileged winners. The casino only gets to keep a relatively indistinct % of all the odds allotted.
The casino one armed bandit software controls each part of the machine, from the flickering lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is produced by the RNG which relates to the pictures on the reel.
