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

Casino slot games have Random Number Generators that are endlessly generating combos, even when the game is not active.

Running concurrently with the Random Number Generator of the casino slot machine is the payout rate percent.

The payout percent controls how much the slot machine game will pay out, for eg the payout per cent might be ninety per cent, which means the slot machine will pay 90% of all the bets played, and the casino simply gets to keep ten per cent.

This does not mean that every time you bet ten credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine game just will not payout for a bit, and then suddenly fire up a hot streak and you might catch the big top prize.

The payoff %s will vary between the various games and some of the most famous casinos, such as Golden Online Casino, which offers a payout rate of up to 95 %!

So, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a number of chosen winners. The casino only gets to keep a basically tiny percentage of all the bets placed.

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

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