Modern casino Slots are controlled by computer software, and the winning %s are pre-programmed into the software.
Casino slot games have Random Number Generators which are constantly generating combos, even when the slot machine game is not active.
Running concurrently with the RNG of the casino one-armed bandit is the pay out rate %.
The pay out percentage controls how much the one-armed bandit will pay out, for eg the payout % might be ninety per cent, meaning the slot machine will pay out ninety percent of all the wagers played, … the casino gets to keep 10 per cent.
This really does not mean that each and every time you bet ten credits you will receive nine in return – where is the fun and thrill in that? Instead, the casino slot machine just will not pay out for a little while, and then suddenly jump on a hot streak and you might draw the big pot prize.
The payoff percentages most likely will vary between the assorted games and a handful of the most famous casinos, for instance Golden Online Casino, which tenders a payout of up to 95 %!
So, in essence, the slot machine game takes all the currency played into it and pays it out to some chosen winners. The casino only gets to keep a averagely tiny percent of all the bets allotted.
The casino one armed bandit software controls every single part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which relates to the pictures on the reel.
