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

Casino slot machine games have Random # Generators that are continually generating combos, even when the game is not active.

Running simultaneously with the RNG of the casino slot machine game is the pay out rate percent.

The payout % controls how much the slot machine game will pay, for e.g. the pay out percentage might be ninety per cent, meaning the slot machine game will payout ninety per cent of all the wagers played, and the casino only gets to keep 10%.

This doesn’t imply that each and every time you bet ten credits you will receive nine in return – where’s the fun and exhilaration in that? Instead, the casino slot machine won’t payout for a bit, and then suddenly fire up a hot streak and you might hit a big jackpot.

The payout percentages will vary between the various games and just a few of the most established casinos, like Golden Online Casino, which tenders a pay out rate of up to 95 percent!

Hence, in essence, the slot machine takes all the currency played into it and pays it out to a handful of privileged winners. The casino only gets to keep a relatively minute percentage of all the plays placed.

The casino slot software controls every single part of the machine, from the flickering lights to the rotating of the reels.

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