Modern casino Slots are controlled by computer software, and the win %s are preprogrammed into the computer software.
Casino slot machines have Random # Generators that are continuously generating combos, even when the machine is not active.
Running in unison with the Random Number Generator of the casino slot machine is the payout %.
The pay out percentage controls how much the slot machine will payout, for e.g. the pay % could be ninety per cent, which means the slot game will payout ninety per cent of all the bets played, and the casino simply gets to keep 10 per cent.
This doesn’t imply that each and every time you bet 10 credits you will receive nine in return – where is the fun and excitement in that? Instead, the casino one arm bandit just won’t pay out for a bit, and then suddenly jump on a hot streak and you might draw the big jackpot prize.
The pay out percentages shall vary between the different games and several of the most acclaimed casinos, like Golden Online Casino, which hands out a cash payment of up to ninety five %!
Thus, in essence, the slot machine takes all the money played into it and pays it out to some fortunate winners. The casino only gets to keep a relatively low per cent of all the gambles made.
The casino slot software controls any part of the machine, from the flashing lights to the revolving of the reels.
When you hit spin on the slot machine, a combination is developed by the RNG which relates to the pictures on the reel.
