Modern casino Slots are controlled by computer software, and the win percentages are preprogrammed into the game software.
Casino slot machines have Random Number Generators that are continuously generating combinations, even when the slot machine is not currently being played.
Running synchronously with the RNG of the casino slot machine game is the pay out rate %.
The payout percentage controls how much the slot machine will pay out, for e.g. the pay per cent may be ninety per cent, which means the slot machine game will payout ninety percent of all the wagers played, and the casino only gets to keep ten percent.
This is not to say that each time you bet 10 credits you will receive nine in return – where’s the fun and exhilaration in that? Instead, the casino slot machine game just won’t payout for a little while, and then suddenly hit a hot streak and you might catch the big grand prize.
The pay out %s usually will vary between the differing games and a couple of the most favored casinos, such as Golden Online Casino, which gives a payout of up to ninety-five %!
Thus, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a few fortunate winners. The casino only gets to keep a averagely small per cent of all the stakes allotted.
The casino one armed bandit software controls each part of the machine, from the flashing lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which corresponds to the pictures on the reel.
