Modern casino one armed bandits are controlled by computer software, and the winner percentages are pre-programmed into the computer software.
Casino slot games have Random # Generators that are eternally generating combos, even when the machine is not currently being played.
Running concurrently with the Random Number Generator of the casino one-armed bandit is the pay out percentage.
The pay out % controls how much the slot machine will payout, for example the payout percent could be ninety percent, meaning the slot machine will pay out ninety percent of all the stakes played, … the casino simply gets to keep 10%.
This does not mean that for every time you bet ten credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino slot just will not payout for a bit, and then suddenly go on a hot streak and you might draw the big grand prize.
The pay off %s usually will vary between the alternate games and some of the highly acclaimed casinos, e.g. Golden Online Casino, which tenders a pay out of up to 95 per cent!

The casino slot machine software controls each and every part of the machine, from the flickering lights to the revolving 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.
