Modern casino one armed bandits are controlled by a computer, and the winner %s are preprogrammed into the software.
Casino slot games have Random Number Generators that are constantly generating combos, even when the machine is not currently being played.
Running in sync with the RNG of the casino one-armed bandit is the pay out percent.
The pay out percent controls just how much the slot machine will payout, for eg the payout percent may be 90%, which means the slot game will payout ninety per cent of all the bets played, and the casino gets to keep 10 percent.
This does not mean that for every time you bet 10 credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino one arm bandit just will not pay out for a bit, and then suddenly fire up a hot streak and you might draw the big grand prize.
The payout %s shall vary between the different games and just a few of the very common casinos, e.g. Golden Online Casino, which offers a cash payment of up to 95 percent!
Thus, in essence, the slot machine game takes all the dough played into it and pays it out to some privileged winners. The casino only gets to keep a fairly low percent of all the wagers put out.
The casino slot software controls any part of the machine, from the blinking lights to the spinning of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which associates with the pictures on the reel.
