Modern casino slot machines are controlled by computer software, and the winner percentages are preprogrammed into the gaming software.
Casino one armed bandits have Random Number Generators that are ceaselessly generating combos, even when the game is not currently being played.
Running concurrently with the random # generator of the casino slot machine game is the pay out rate per cent.
The pay out percentage controls just how much the one-armed bandit will payout, for eg the pay out % might be ninety percent, meaning the one arm bandit will payout ninety per cent of all the bets played, and the casino gets to keep 10 percent.
This does not mean that each and every time you bet 10 credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino one arm bandit just will not pay out for a while, and then suddenly go on a hot streak and you might draw the big top prize.
The payout percentages usually will vary between the different games and a few of the most common casinos, for instance Golden Online Casino, which hands out a payout rate of up to 95 %!
Thus, in essence, the slot machine takes all the money played into it and pays it out to several privileged winners. The casino only gets to keep a relatively petite percent of all the stakes made.
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 associates with the pictures on the reel.
