Modern casino slot machines are controlled by computer chips and software, and the win %s are pre-programmed into the software.
Casino slot games have Random # Generators which are eternally generating combinations, even when the slot machine is not being played.
Running simultaneously with the RNG of the casino slot machine game is the payout rate percent.
The payout % controls how much the slot machine game will pay, for example the pay out percentage could be ninety per cent, which means the slot machine game will pay ninety per cent of all the wagers played, … the casino simply gets to keep ten percent.
This is not to say that each and every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot will not pay out for a while, and then suddenly fire up a hot streak and you might catch the big pot prize.
The pay off percentages will vary between the differing games and just a few of the very famous casinos, such as Golden Online Casino, which puts forth a payout of up to ninety-five percentage!
Hence, in essence, the slot machine game takes all the money played into it and pays it out to several lucky winners. The casino only gets to keep a relatively indistinct percent of all the plays allocated.
The casino one armed bandit software controls each part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which connects with the pictures on the reel.
