Modern casino slot machines are controlled by computer chips and software, and the win percentages are preprogrammed into the computer software.
Casino slot games have Random # Generators which are eternally generating combos, even when the game is not active.
Running synchronously with the random # generator of the casino slot machine game is the pay out rate %.
The payout percentage controls just how much the slot machine will pay out, for e.g. the payout per cent could be ninety percent, which means the slot game will pay 90% of all the wagers played, … the casino gets to keep ten per cent.
This doesn’t imply that for every time you bet ten credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino slot just will not payout for a little while, and then suddenly jump on a hot streak and you might hit a big top prize.
The payout percentages will most likely vary between the differing games and just a few of the very famous casinos, for instance Golden Online Casino, which offers a payout rate of up to ninety-five percent!
So, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a couple of lucky winners. The casino only gets to keep a fairly tiny percent of all the odds made.
The casino one armed bandit software controls every part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which connects with the pictures on the reel.
