Modern casino slot machine games are controlled by computer software, and the win percentages are preprogrammed into the game software.

Casino one armed bandits have Random # Generators which are constantly generating combos, even when the machine is not currently being played.

Running concurrently with the Random Number Generator of the casino one-armed bandit is the pay out percentage.

The payout percentage controls how much the slot machine game will pay out, for eg the pay out per cent might be ninety per cent, meaning the slot game will pay out 90% of all the bets played, … the casino will then get to keep 10 percent.

This does not mean that each time you bet ten credits you will receive nine in return – where is the fun and excitement in that? Instead, the casino slot will not payout for a bit, and then suddenly go on a hot streak and you might draw the big pot prize.

The payout percentages usually will vary between the differing games and a handful of the very famous casinos, for e.g Golden Online Casino, which puts forth a payment of up to 95 percentage!

Therefore, in essence, the slot machine game takes all the money played into it and pays it out to a couple of lucky winners. The casino only gets to keep a relatively low percentage of all the stakes allotted.

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

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