Modern casino slot machine games are controlled by a computer, and the win %s are preprogrammed into the game software.
Casino Slots have Random Number Generators that are continually generating combinations, even when the slot machine is not being played.
Running simultaneously with the Random Number Generator of the casino one-armed bandit is the payout %.
The payout percentage controls how much the one-armed bandit will pay out, for e.g. the payout percent may be ninety percent, meaning the slot machine will pay 90% of all the bets played, … the casino simply gets to keep 10 per cent.
This is not to say that every time you bet ten credits you will receive nine in return – where is the fun and excitement in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly start up a hot streak and you might draw the big top prize.
The pay off %s will tend to vary between the alternate games and some of the highly acclaimed casinos, for e.g Golden Online Casino, which tenders a payment of up to ninety five percent!
Hence, in essence, the slot machine game takes all the dough played into it and pays it out to some lucky winners. The casino only gets to keep a considerably minute % of all the wagers allocated.
The casino slot machine software controls every single part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which is linked to the pictures on the reel.
