Modern casino one armed bandits are controlled by computer software, and the winning percentages are preprogrammed into the software.
Casino slot games have Random # Generators that are continuously generating combinations, even when the slot machine game is not active.
Running concurrently with the Random Number Generator of the casino slot machine is the pay out rate percent.
The payout % controls just how much the slot machine game will pay out, for example the pay out percentage may be ninety percent, which means the slot game will pay 90% of all the wagers played, … the casino simply gets to keep ten per cent.
This really does not mean that each and every time you bet ten credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino slot machine game will not pay out for a little while, and then suddenly go on a hot streak and you might catch the big pot prize.
The pay out %s will very likely vary between the different games and a few of the notably popular casinos, for instance Golden Online Casino, which hands out a payment of up to ninety-five percentage!
As a result, in essence, the slot machine takes all the $$$$$ played into it and pays it out to some lucky winners. The casino only gets to keep a basically tiny percentage of all the gambles allotted.
The casino slot machine 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 generated by the RNG which relates to the pictures on the reel.
