Modern casino Slots are controlled by computer software, and the win %s are pre-programmed into the software.
Casino slot machines have Random # Generators which are constantly generating combos, even when the game is not active.
Running in sync with the Random Number Generator of the casino slot machine game is the payout rate %.
The pay out percent controls how much the one-armed bandit will payout, for example the pay % might be ninety per cent, meaning the slot machine game will pay 90% of all the wagers played, … the casino will then get to keep ten percent.
This does not mean that each and every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino one arm bandit will not payout for a while, and then suddenly fire up a hot streak and you might draw the big jackpot prize.
The pay out %s usually will vary between the various games and a handful of the extremely favored casinos, for e.g Golden Online Casino, which tenders a cash payment of up to 95 per cent!
Thus, in essence, the slot machine game takes all the money played into it and pays it out to a number of privileged winners. The casino only gets to keep a considerably minute % of all the stakes put out.
The casino slot software controls any part of the machine, from the flashing lights to the revolving of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which associates with the pictures on the reel.
