Modern casino slot games are controlled by computer software, and the winning %s are pre-programmed into the computer software.
Casino slot machine games have RNGs that are ceaselessly generating combos, even when the game is not currently being played.
Running concurrently with the random # generator of the casino slot machine is the pay out percentage.
The pay out % controls how much the slot machine game will pay, for e.g. the payout per cent could be ninety percent, which means the slot machine game will payout 90% of all the wagers played, … the casino will then get to keep ten percent.
This doesn’t mean that each time you bet ten credits you will receive 9 in return – where is the fun and thrill in that? Instead, the casino slot machine game won’t pay out for a bit, and then suddenly jump on a hot streak and you might draw the big jackpot.
The profit percentages most likely will vary between the different games and just a few of the most popular casinos, e.g. Golden Online Casino, which gives a payout of up to ninety-five %!
This means that, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a number of fortunate winners. The casino only gets to keep a basically petite per cent of all the gambles allocated.
The casino slot software controls each and every part of the machine, from the flickering lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which is linked to the pictures on the reel.
