Modern casino slot machines are controlled by a computer, and the winning %s are pre-programmed into the software.
Casino slot machine games have RNGs that are continuously generating combinations, even when the machine is not currently being played.
Running synchronously with the Random Number Generator of the casino slot machine is the payout per cent.
The pay out percent controls how much the one-armed bandit will payout, for e.g. the payout percent could be 90%, meaning the slot machine will pay ninety per cent of all the bets played, and the casino simply gets to keep 10 per cent.
This doesn’t mean that each and every time you bet 10 credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino slot machine game will not pay out for a little while, and then suddenly jump on a hot streak and you might catch the big jackpot.
The profit %s will vary between the differing games and some of the very famous casinos, for example Golden Online Casino, which hands out a pay out rate of up to ninety-five percent!
Therefore, in essence, the slot machine game takes all the cash played into it and pays it out to a few privileged winners. The casino only gets to keep a basically small % of all the odds allocated.
The casino slot machine software controls each part of the machine, from the flickering lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which associates with the pictures on the reel.
