Modern casino slot machines are controlled by computer chips and software, and the winner percentages are preprogrammed into the gaming software.
Casino slot games have RNGs that are continuously generating combinations, even when the game is not being played.
Running in sync with the random # generator of the casino slot machine is the pay out %.
The pay out percentage controls how much the one-armed bandit will payout, for example the payout percentage may be ninety percent, meaning the slot machine game will pay ninety percent of all the wagers played, and the casino only gets to keep ten percent.
This does not imply that each time you bet 10 credits you will receive 9 in return – where is the fun … fascination in that? Instead, the casino one arm bandit will not pay out for a bit, and then suddenly hit a hot streak and you might hit a big jackpot.
The pay off %s usually will vary between the assorted games and some of the highly common casinos, for e.g Golden Online Casino, which gives a payment of up to ninety five percent!
Thus, in essence, the one-armed bandit takes all the funds played into it and pays it out to a few fortunate winners. The casino only gets to keep a relatively petite % of all the bets placed.
The casino slot software controls every single part of the machine, from the flickering lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is set up by the RNG which corresponds to the pictures on the reel.
