Modern casino slot games are controlled by computer software, and the winning %s are pre-programmed into the software.
Casino slot machines have RNGs which are ceaselessly generating combinations, even when the machine is not currently being played.
Running jointly with the Random Number Generator of the casino slot machine is the pay out rate percentage.
The payout percentage controls just how much the one-armed bandit will pay out, for e.g. the pay per cent may be ninety percent, meaning the slot machine game will pay out ninety per cent of all the stakes played, … the casino simply gets to keep 10 per cent.
This really does not mean that every time you bet 10 credits you will receive 9 in return – where is the fun … exhilaration in that? Instead, the casino slot machine game just won’t payout for a little while, and then suddenly hit a hot streak and you might hit a big jackpot.
The pay off percentages will tend to vary between the differing games and a couple of the most established casinos, such as Golden Online Casino, which hands out a cash payment of up to ninety-five percent!
Thus, in essence, the slot machine game takes all the cash played into it and pays it out to several chosen winners. The casino only gets to keep a generally tiny % of all the gambles placed.
The casino slot software controls each part of the machine, from the dazzling lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which is linked to the pictures on the reel.
