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

Casino slot machines have Random # Generators that are endlessly generating combos, even when the machine is not currently being played.

Running side by side with the random # generator of the casino slot machine game is the payout per cent.

The payout percentage controls just how much the slot machine game will payout, for example the pay per cent might be ninety per cent, meaning the slot machine will pay out 90% of all the stakes played, and the casino simply gets to keep 10 percent.

This doesn’t mean that each and every time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine will not payout for a little while, and then suddenly go on a hot streak and you might hit a big jackpot prize.

The payout percentages will vary between the differing games and a handful of the extremely acclaimed casinos, e.g. Golden Online Casino, which offers a payout of up to 95 %!

This means that, in essence, the one-armed bandit takes all the money played into it and pays it out to some chosen winners. The casino only gets to keep a generally tiny per cent of all the stakes made.

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

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