Modern casino slot games are controlled by computer software, and the winner %s are preprogrammed into the computer software.
Casino Slots have Random Number Generators which are constantly generating combinations, even when the machine is not being played.
Running side by side with the Random Number Generator of the casino one-armed bandit is the payout percentage.
The payout percent controls just how much the slot machine game will payout, for e.g. the pay % may be ninety per cent, meaning the slot machine will pay out 90% of all the bets played, … the casino simply gets to keep ten percent.
This does not mean that for every time you bet ten credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino one arm bandit just won’t payout for a little while, and then suddenly go on a hot streak and you might hit a big grand prize.
The pay out %s will vary between the various games and just a few of the very acclaimed casinos, for example Golden Online Casino, which hands out a pay out rate of up to ninety-five percentage!
So, in essence, the slot machine takes all the currency played into it and pays it out to a couple of chosen winners. The casino only gets to keep a averagely small per cent of all the gambles placed.
The casino slot software controls every part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which relates to the pictures on the reel.
