Modern casino slot games are controlled by computer software, and the winning percentages are pre-programmed into the computer software.
Casino slot games have Random Number Generators which are ceaselessly generating combinations, even when the slot machine game is not being played.
Running synchronously with the RNG of the casino one-armed bandit is the payout percent.
The pay out % controls just how much the slot machine will payout, for eg the pay out % might be ninety percent, meaning the one arm bandit will payout 90% of all the bets played, … the casino will then get to keep 10 percent.
This doesn’t imply that each time you bet 10 credits you will receive 9 in return – where is the fun … excitement in that? Instead, the casino slot machine just will not payout for a little while, and then suddenly jump on a hot streak and you might catch the big top prize.
The payout percentages will very likely vary between the various games and a couple of the very favored casinos, for example Golden Online Casino, which gives a payout rate of up to ninety five percent!
Therefore, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to several fortunate winners. The casino only gets to keep a basically minute per cent of all the stakes allocated.
The casino slot machine software controls each part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which corresponds to the pictures on the reel.
