Modern casino Slots are controlled by computer software, and the winning %s are preprogrammed into the computer software.
Casino slot games have Random Number Generators that are continuously generating combos, even when the game is not currently being played.
Running in unison with the random # generator of the casino slot machine game is the pay out rate %.
The pay out % controls just how much the one-armed bandit will pay, for e.g. the payout percentage may be 90%, which means the slot machine will pay out ninety percent of all the wagers played, … the casino simply gets to keep 10%.
This is not to say that for every time you bet ten credits you will receive 9 in return – where is the fun … thrill in that? Instead, the casino slot machine won’t payout for a while, and then suddenly hit a hot streak and you might draw the big pot prize.
The pay out percentages will definitely vary between the differing games and just a few of the highly acclaimed casinos, like Golden Online Casino, which offers a cash payment of up to ninety five per cent!
So, in essence, the slot machine takes all the $$$$$ played into it and pays it out to several privileged winners. The casino only gets to keep a averagely tiny percentage of all the plays allotted.
The casino one armed bandit software controls each and every part of the machine, from the blinking lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which connects with the pictures on the reel.
