Modern casino slot machine games are controlled by computer chips and software, and the winner percentages are preprogrammed into the gaming software.
Casino Slots have RNGs which are continually generating combinations, even when the slot machine is not currently being played.
Running jointly with the Random Number Generator of the casino one-armed bandit is the payout rate percent.
The payout % controls just how much the one-armed bandit will payout, for e.g. the pay percentage may be ninety per cent, meaning the slot machine will pay out 90% of all the stakes played, … the casino simply gets to keep 10%.
This does not mean that for every time you bet 10 credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino one arm bandit just won’t payout for a bit, and then suddenly go on a hot streak and you might catch the big pot prize.
The pay out %s will most likely vary between the various games and some of the most common casinos, e.g. Golden Online Casino, which puts forth a pay out of up to ninety-five percent!
Therefore, in essence, the slot machine takes all the dough played into it and pays it out to a few chosen winners. The casino only gets to keep a averagely low percentage of all the plays put out.
The casino one armed bandit software controls every single part of the machine, from the flickering lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which corresponds to the pictures on the reel.
