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

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

Running collectively with the random # generator of the casino one-armed bandit is the pay out rate %.

The payout percent controls just how much the slot machine game will payout, for example the pay out per cent may be 90%, meaning the slot machine will pay ninety per cent of all the wagers played, and the casino will then get to keep 10 percent.

This really does not mean that every time you bet ten credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot just won’t pay out for a little while, and then suddenly hit a hot streak and you might draw the big pot prize.

The pay out %s will vary between the assorted games and a couple of the highly established casinos, e.g. Golden Online Casino, which tenders a pay out rate of up to ninety-five percent!

Therefore, in essence, the slot machine takes all the currency played into it and pays it out to a couple of privileged winners. The casino only gets to keep a fairly small % of all the gambles put out.

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

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