Modern casino slot machines are controlled by computer software, and the win percentages are pre-programmed into the game software.

Casino slot machines have RNGs which are endlessly generating combos, even when the slot machine is not being played.

Running synchronously with the Random Number Generator of the casino slot machine game is the payout rate percentage.

The payout per cent controls how much the slot machine will pay, for example the pay out % might be ninety per cent, meaning the one arm bandit will pay out ninety per cent of all the wagers played, … the casino simply gets to keep 10%.

This does not imply that every time you bet 10 credits you will receive nine in return – where’s the fun … thrill in that? Instead, the casino slot machine just will not pay out for a little while, and then suddenly go on a hot streak and you might draw the big top prize.

The pay out %s most likely will vary between the different games and a handful of the most popular casinos, e.g. Golden Online Casino, which hands out a pay out rate of up to ninety-five %!

This means that, in essence, the slot machine takes all the money played into it and pays it out to a few chosen winners. The casino only gets to keep a averagely minute % of all the odds placed.

The casino one armed bandit software controls each part of the machine, from the dazzling lights to the rolling of the reels.

When you hit spin on the slot machine, a combination is developed by the RNG which connects with the pictures on the reel.
