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

Casino slot games have RNGs that are continuously generating combos, even when the game is not active.

Running jointly with the RNG of the casino slot machine is the payout rate percent.

The payout percent controls just how much the slot machine will payout, for e.g. the pay percent might be ninety percent, which means the slot machine will payout ninety percent of all the bets played, and the casino only gets to keep 10 percent.

This really does not mean that for every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit just won’t pay out for a little while, and then suddenly fire up a hot streak and you might draw the big pot prize.

The payout %s will most likely vary between the various games and a couple of the highly common casinos, like Golden Online Casino, which tenders a payout of up to 95 per cent!

Thus, in essence, the slot machine game takes all the money played into it and pays it out to a few chosen winners. The casino only gets to keep a averagely tiny % of all the plays allotted.

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

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