Modern casino Slots are controlled by a computer, and the win %s are preprogrammed into the computer software.
Casino slot games have Random Number Generators that are eternally generating combos, even when the slot machine game is not active.
Running in sync with the Random Number Generator of the casino slot machine is the payout percent.
The payout percent controls how much the one-armed bandit will pay out, for eg the pay out per cent might be 90%, which means the one arm bandit will pay 90% of all the stakes played, and the casino simply gets to keep 10 percent.
This does not mean that every time you bet 10 credits you will receive nine in return – where is the fun … excitement in that? Instead, the casino slot machine just won’t pay out for a little while, and then suddenly hit a hot streak and you might catch the big grand prize.
The pay off percentages will tend to vary between the assorted games and just a few of the notably acclaimed casinos, for e.g Golden Online Casino, which tenders a pay out of up to ninety five per cent!
So, in essence, the slot machine takes all the dough played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a generally tiny percent of all the stakes made.
The casino slot machine software controls every part of the machine, from the dazzling lights to the turning of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which corresponds to the pictures on the reel.
