Modern casino one armed bandits are controlled by a computer, and the win percentages are preprogrammed into the computer software.

Casino slot games have Random # Generators which are continually generating combinations, even when the machine is not being played.

Running jointly with the RNG of the casino one-armed bandit is the pay out %.

The pay out percentage controls just how much the slot machine game will pay, for eg the pay out per cent may be ninety per cent, which means the slot machine will pay out ninety percent of all the bets played, … the casino gets to keep 10 per cent.

This really does not mean that each and every time you bet 10 credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino slot machine will not payout for a bit, and then suddenly start up a hot streak and you might catch the big grand prize.

The pay off percentages most likely will vary between the differing games and some of the most popular casinos, like Golden Online Casino, which gives a payment of up to ninety-five per cent!

So, in essence, the slot machine game takes all the cash played into it and pays it out to a few privileged winners. The casino only gets to keep a fairly petite % of all the wagers made.

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

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