Modern casino slot machines are controlled by computer chips and software, and the winning %s are preprogrammed into the game software.

Casino slot games have Random Number Generators that are endlessly generating combos, even when the game is not currently being played.

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

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

This does not mean that every time you bet 10 credits you will receive 9 in return – where’s the fun and fascination in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly jump on a hot streak and you might catch the big top prize.

The pay off percentages shall vary between the different games and several of the most common casinos, e.g. Golden Online Casino, which hands out a pay out of up to ninety five percent!

Thus, in essence, the slot machine takes all the $$$$$ played into it and pays it out to some lucky winners. The casino only gets to keep a relatively small percent of all the wagers allocated.

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

When you hit spin on the one-armed bandit, a combination is developed by the RNG which is linked to the pictures on the reel.
