Modern casino Slots are controlled by a computer, and the winning percentages are pre-programmed into the computer software.
Casino slot machine games have RNGs which are endlessly generating combinations, even when the game is not active.
Running concurrently with the random # generator of the casino one-armed bandit is the payout per cent.
The pay out percent controls how much the slot machine game will pay out, for eg the pay percentage may be ninety per cent, meaning the slot game will payout 90% of all the bets played, and the casino gets to keep 10 per cent.
This really does not mean that each time you bet 10 credits you will receive nine in return – where’s the fun and thrill in that? Instead, the casino slot machine won’t pay out for a while, and then suddenly jump on a hot streak and you might hit a big top prize.
The pay off percentages will very likely vary between the assorted games and a handful of the very acclaimed casinos, for example Golden Online Casino, which tenders a payout of up to ninety-five percent!
This means that, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a handful of chosen winners. The casino only gets to keep a fairly indistinct percentage of all the plays placed.
The casino one armed bandit software controls any part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is developed by the RNG which is linked to the pictures on the reel.
