Modern casino Slots are controlled by a computer, and the winning %s are pre-programmed into the computer software.
Casino slot machines have Random Number Generators which are eternally generating combos, even when the machine is not currently being played.
Running synchronously with the Random Number Generator of the casino slot machine is the payout rate %.
The pay out percentage controls how much the slot machine game will pay, for eg the payout percent may be 90%, meaning the slot machine game will pay ninety per cent of all the bets played, … the casino simply gets to keep ten percent.
This doesn’t mean that each and every time you bet 10 credits you will receive 9 in return – where is the fun … fascination in that? Instead, the casino slot machine just will not pay out for a little while, and then suddenly fire up a hot streak and you might catch the big top prize.
The pay out %s most likely will vary between the different games and a handful of the very popular casinos, e.g. Golden Online Casino, which provides a pay out of up to 95 percentage!
Thus, in essence, the slot machine game takes all the money played into it and pays it out to several lucky winners. The casino only gets to keep a averagely tiny per cent of all the odds placed.
The casino slot software controls each part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is developed by the RNG which is linked to the pictures on the reel.
