Modern casino slot machines are controlled by computer chips and software, and the win percentages are pre-programmed into the game software.
Casino slot machines have Random Number Generators which are constantly generating combinations, even when the game is not being played.
Running in unison with the random # generator of the casino one-armed bandit is the pay out rate percent.
The pay out percentage controls how much the one-armed bandit will pay, for eg the pay percentage could be 90%, which means the slot machine game will payout ninety percent of all the wagers played, … the casino gets to keep 10 per cent.
This does not mean that for every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine game just will not pay out for a little while, and then suddenly jump on a hot streak and you might hit a big jackpot prize.
The payout %s will most likely vary between the different games and a handful of the notably popular casinos, for e.g Golden Online Casino, which offers a payout of up to ninety five percentage!
As a result, in essence, the one-armed bandit takes all the currency played into it and pays it out to a couple of lucky winners. The casino only gets to keep a considerably minute percentage of all the gambles made.
The casino one armed bandit software controls each part of the machine, from the dazzling lights to the rolling of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which is linked to the pictures on the reel.
