Modern casino slot machines are controlled by computer software, and the win percentages are preprogrammed into the game software.
Casino slot machines have Random # Generators which are endlessly generating combos, even when the machine is not being played.
Running in sync with the random # generator of the casino slot machine game is the payout rate percentage.
The payout % controls just how much the slot machine game will payout, for e.g. the payout % might be ninety per cent, which means the slot machine game will pay ninety percent of all the bets played, and the casino will then get to keep ten percent.
This does not mean that for every time you bet 10 credits you will receive nine in return – where is the fun … thrill in that? Instead, the casino slot will not pay out for a while, and then suddenly fire up a hot streak and you might hit a big grand prize.
The profit %s most likely will vary between the different games and a couple of the most acclaimed casinos, for e.g Golden Online Casino, which puts forth a cash payment of up to ninety-five percent!
As a result, in essence, the slot machine game takes all the currency played into it and pays it out to some fortunate winners. The casino only gets to keep a averagely minute percentage of all the plays placed.
The casino slot software controls each part of the machine, from the dazzling lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which corresponds to the pictures on the reel.
