Modern casino Slots are controlled by a computer, and the winning %s are preprogrammed into the game software.
Casino one armed bandits have Random # Generators which are continuously generating combinations, even when the machine is not currently being played.
Running side by side with the RNG of the casino slot machine game is the pay out per cent.
The pay out % controls how much the one-armed bandit will payout, for example the pay out percentage may be 90%, meaning the slot machine will payout 90% of all the wagers played, … the casino simply gets to keep 10 per cent.
This does not imply that each time you bet ten credits you will receive nine in return – where is the fun and excitement in that? Instead, the casino slot machine just won’t payout for a bit, and then suddenly fire up a hot streak and you might catch the big grand prize.
The pay out percentages will most likely vary between the different games and a handful of the highly established casinos, for instance Golden Online Casino, which tenders a pay out of up to ninety-five per cent!
As a result, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a number of chosen winners. The casino only gets to keep a relatively small percent of all the gambles made.
The casino slot software controls each and every part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine, a combination is generated by the RNG which connects with the pictures on the reel.
