Modern casino Slots are controlled by computer software, and the win percentages are preprogrammed into the software.
Casino slot machine games have RNGs which are ceaselessly generating combinations, even when the game is not currently being played.
Running simultaneously with the RNG of the casino one-armed bandit is the pay out rate percent.
The pay out percentage controls how much the slot machine game will pay, for e.g. the pay out percent might be 90%, which means the slot machine will pay 90% of all the stakes played, and the casino only gets to keep ten per cent.
This does not mean that each time you bet ten credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine won’t pay out for a little while, and then suddenly jump on a hot streak and you might catch the big pot prize.
The profit %s will definitely vary between the differing games and just a few of the notably common casinos, for example Golden Online Casino, which hands out a cash payment of up to ninety-five %!
Hence, in essence, the slot machine game takes all the funds played into it and pays it out to a number of privileged winners. The casino only gets to keep a relatively small percent of all the bets placed.
The casino slot machine software controls every single part of the machine, from the flickering lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which associates with the pictures on the reel.
