Modern casino one armed bandits are controlled by computer chips and software, and the winner percentages are pre-programmed into the game software.
Casino slot games have RNGs that are constantly generating combinations, even when the slot machine is not active.
Running in unison with the random # generator of the casino slot machine game is the pay out rate per cent.
The payout % controls just how much the slot machine will payout, for example the pay percentage may be ninety percent, meaning the slot machine game will pay out ninety percent of all the stakes played, and the casino gets to keep ten percent.
This really does not mean that each and every time you bet ten credits you will receive 9 in return – where is the fun and fascination in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly go on a hot streak and you might hit a big jackpot.
The payout percentages will very likely vary between the differing games and several of the highly established casinos, for example Golden Online Casino, which puts forth a payout rate of up to ninety five percentage!
So, in essence, the slot machine takes all the cash played into it and pays it out to a number of chosen winners. The casino only gets to keep a generally tiny percent of all the wagers allocated.
The casino one armed bandit software controls every single part of the machine, from the flickering lights to the turning of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which relates to the pictures on the reel.
