Modern casino one armed bandits are controlled by computer software, and the win percentages are preprogrammed into the computer software.
Casino slot machine games have Random # Generators that are constantly generating combinations, even when the slot machine game is not active.
Running in unison with the Random Number Generator of the casino slot machine game is the pay out percentage.
The payout percentage controls how much the slot machine game will pay, for eg the pay per cent may be 90%, meaning the slot machine will payout 90% of all the bets played, … the casino simply gets to keep 10%.
This does not imply that for every time you bet 10 credits you will receive 9 in return – where’s the fun and fascination in that? Instead, the casino slot machine just won’t payout for a little while, and then suddenly hit a hot streak and you might catch the big jackpot.
The pay out percentages will tend to vary between the different games and a handful of the most established casinos, for e.g Golden Online Casino, which tenders a payment of up to ninety five percentage!
Hence, in essence, the one-armed bandit takes all the cash played into it and pays it out to a few privileged winners. The casino only gets to keep a relatively low percent of all the odds placed.
The casino one armed bandit software controls any part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which is linked to the pictures on the reel.
