Modern casino one armed bandits are controlled by computer chips and software, and the winning %s are pre-programmed into the software.
Casino slot games have Random # Generators that are eternally generating combinations, even when the machine is not active.
Running in unison with the RNG of the casino one-armed bandit is the pay out rate %.
The payout per cent controls how much the slot machine will pay out, for e.g. the pay percentage may be 90%, which means the one arm bandit will pay 90% of all the bets played, … the casino will then get to keep 10 percent.
This does not mean that each time you bet 10 credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot won’t pay out for a while, and then suddenly start up a hot streak and you might catch the big jackpot prize.
The pay out percentages will most likely vary between the different games and a handful of the notably common casinos, for example Golden Online Casino, which gives a payment of up to ninety five percent!
As a result, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to several chosen winners. The casino only gets to keep a relatively small % of all the odds allocated.
The casino one armed bandit software controls each part of the machine, from the dazzling lights to the rolling of the reels.
When you hit spin on the one-armed bandit, a combination is developed by the RNG which corresponds to the pictures on the reel.
