Modern casino slot games are controlled by a computer, and the winner %s are preprogrammed into the gaming software.
Casino slot machines have Random Number Generators which are endlessly generating combinations, even when the game is not currently being played.
Running collectively with the random # generator of the casino slot machine is the pay out per cent.
The pay out percent controls just how much the slot machine will pay, for eg the payout % might be ninety percent, which means the slot game will payout ninety per cent of all the stakes played, and the casino will then get to keep 10 percent.
This does not mean that each time you bet ten credits you will receive 9 in return – where is the fun and fascination in that? Instead, the casino slot machine will not pay out for a little while, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The pay off %s will definitely vary between the various games and a few of the extremely acclaimed casinos, such as Golden Online Casino, which offers a pay out rate of up to ninety-five per cent!
So, in essence, the slot machine game takes all the money played into it and pays it out to a few chosen winners. The casino only gets to keep a averagely small % of all the gambles allocated.
The casino slot software controls every part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which is linked to the pictures on the reel.
