Modern casino Slots are controlled by computer software, and the winning %s are pre-programmed into the computer software.

Casino slot machine games have RNGs that are endlessly generating combinations, even when the slot machine game is not being played.

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

The payout % controls just how much the slot machine will pay out, for e.g. the pay out percentage might be ninety per cent, meaning the slot machine will payout ninety percent of all the wagers played, … the casino will then get to keep ten percent.

This does not mean that for every time you bet 10 credits you will receive 9 in return – where’s the fun and fascination in that? Instead, the casino slot machine just won’t pay out for a bit, and then suddenly fire up a hot streak and you might hit a big grand prize.

The pay off percentages will most likely vary between the various games and some of the highly favored casinos, e.g. Golden Online Casino, which provides a payment of up to ninety five percentage!

Therefore, in essence, the one-armed bandit takes all the funds played into it and pays it out to a couple of chosen winners. The casino only gets to keep a generally minute per cent of all the wagers put out.

The casino slot software controls each part of the machine, from the flashing lights to the circulating of the reels.

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