Modern casino Slots are controlled by a computer, and the winning %s are preprogrammed into the computer software.

Casino slot machines have Random Number Generators which are continually generating combinations, even when the game is not active.

Running in sync with the random # generator of the casino one-armed bandit is the payout rate percentage.

The pay out percentage controls how much the slot machine game will pay, for e.g. the pay out per cent could be ninety per cent, meaning the slot machine will pay ninety per cent of all the stakes played, … the casino gets to keep 10 percent.

This doesn’t mean that for every time you bet 10 credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot will not pay out for a bit, and then suddenly jump on a hot streak and you might draw the big jackpot prize.

The pay off %s will most likely vary between the assorted games and a handful of the very established casinos, e.g. Golden Online Casino, which offers a cash payment of up to ninety-five per cent!

Hence, in essence, the slot machine takes all the funds played into it and pays it out to a handful of fortunate winners. The casino only gets to keep a basically low percentage of all the wagers placed.

The casino slot software controls every single 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 relates to the pictures on the reel.
