Modern casino slot machines are controlled by computer software, and the win percentages are preprogrammed into the gaming software.
Casino one armed bandits have RNGs which are continually generating combinations, even when the game is not currently being played.
Running in sync with the RNG of the casino slot machine is the pay out per cent.
The pay out percentage controls just how much the one-armed bandit will payout, for example the pay % may be ninety per cent, which means the slot game will pay 90% of all the stakes played, … the casino simply gets to keep ten percent.
This does not imply that every time you bet 10 credits you will receive 9 in return – where is the fun and fascination in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly go on a hot streak and you might hit a big jackpot prize.
The payout %s most likely will vary between the different games and a couple of the very common casinos, for example Golden Online Casino, which offers a cash payment of up to ninety five percentage!
So, in essence, the one-armed bandit takes all the currency played into it and pays it out to some privileged winners. The casino only gets to keep a considerably tiny per cent of all the wagers put out.
The casino slot software controls each and every part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which relates to the pictures on the reel.
