Modern casino slot machines are controlled by a computer, and the winner percentages are pre-programmed into the software.

Casino slot machine games have RNGs which are endlessly generating combinations, even when the slot machine game is not active.

Running jointly with the RNG of the casino slot machine is the pay out percent.

The pay out per cent controls just how much the slot machine will pay, for eg the payout percent could be ninety per cent, meaning the slot machine game will pay ninety percent of all the wagers played, … the casino gets to keep 10 percent.

This does not imply that every time you bet 10 credits you will receive 9 in return – where’s the fun … exhilaration in that? Instead, the casino slot just won’t pay out for a while, and then suddenly fire up a hot streak and you might draw the big jackpot.

The pay out %s will definitely vary between the different games and a few of the notably famous casinos, e.g. Golden Online Casino, which offers a cash payment of up to ninety-five %!

Therefore, in essence, the slot machine takes all the $$$$$ played into it and pays it out to some chosen winners. The casino only gets to keep a fairly tiny per cent of all the gambles put out.

The casino slot software controls every part of the machine, from the dazzling lights to the turning of the reels.

When you hit spin on the slot machine, a combination is formed by the RNG which associates with the pictures on the reel.
