Modern casino slot machines are controlled by computer chips and software, and the winner percentages are pre-programmed into the computer software.
Casino one armed bandits have Random # Generators which are ceaselessly generating combos, even when the machine is not being played.
Running synchronously with the Random Number Generator of the casino slot machine game is the payout per cent.
The payout percentage controls how much the slot machine will payout, for example the payout per cent might be ninety per cent, meaning the slot game will pay ninety per cent of all the stakes played, … the casino gets to keep 10 per cent.
This does not imply that every time you bet ten credits you will receive nine in return – where is the fun … excitement in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The profit percentages will most likely vary between the differing games and a couple of the most famous casinos, e.g. Golden Online Casino, which tenders a pay out rate of up to ninety-five percentage!
So, in essence, the slot machine takes all the funds played into it and pays it out to a few chosen winners. The casino only gets to keep a fairly tiny % of all the plays put out.
The casino slot software controls each and every part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which relates to the pictures on the reel.
