Modern casino slot games are controlled by a computer, and the win percentages are pre-programmed into the game software.

Casino Slots have RNGs which are eternally generating combos, even when the slot machine is not being played.

Running synchronously with the random # generator of the casino one-armed bandit is the pay out percent.

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

This is not to say that each and every time you bet ten credits you will receive nine in return – where is the fun … thrill in that? Instead, the casino one arm bandit just will not payout for a little while, and then suddenly hit a hot streak and you might draw the big pot prize.

The pay off %s will vary between the different games and a handful of the notably favored casinos, like Golden Online Casino, which hands out a pay out rate of up to ninety five per cent!

This means that, in essence, the one-armed bandit takes all the currency played into it and pays it out to some lucky winners. The casino only gets to keep a fairly minute percent of all the plays put out.

The casino slot software controls each and every 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 generated by the RNG which connects with the pictures on the reel.
