Modern casino slot machines are controlled by computer software, and the win percentages are pre-programmed into the game software.
Casino Slots have RNGs that are eternally generating combinations, even when the slot machine game is not active.
Running side by side with the random # generator of the casino slot machine game is the pay out percentage.
The payout % controls how much the slot machine will payout, for eg the pay % could be ninety per cent, meaning the slot machine game will pay out 90% of all the stakes played, and the casino gets to keep ten per cent.
This does not mean that each and every time you bet ten credits you will receive nine in return – where’s the fun and thrill in that? Instead, the casino slot machine won’t payout for a while, and then suddenly start up a hot streak and you might catch the big grand prize.
The pay off %s will most likely vary between the different games and a couple of the extremely acclaimed casinos, for e.g Golden Online Casino, which offers a payout of up to ninety-five percentage!
So, in essence, the one-armed bandit takes all the dough played into it and pays it out to a few privileged winners. The casino only gets to keep a fairly petite percentage of all the odds made.
The casino slot software controls every single part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which connects with the pictures on the reel.
