Modern casino Slots are controlled by a computer, and the win %s are pre-programmed into the gaming software.

Casino slot machines have Random Number Generators which are endlessly generating combinations, even when the machine is not being played.

Running simultaneously with the random # generator of the casino one-armed bandit is the payout %.

The payout percentage controls how much the slot machine will payout, for e.g. the payout percentage may be 90%, meaning the slot machine game will pay out ninety percent of all the bets played, … the casino simply gets to keep 10 per cent.

This is not to say that each time you bet ten credits you will receive 9 in return – where’s the fun and excitement in that? Instead, the casino slot machine game just will not payout for a bit, and then suddenly go on a hot streak and you might hit a big jackpot prize.

The pay out %s will vary between the alternate games and several of the very popular casinos, like Golden Online Casino, which offers a payout rate of up to ninety-five %!

Therefore, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a few fortunate winners. The casino only gets to keep a relatively petite percentage of all the wagers put out.

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

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