Modern casino Slots are controlled by computer software, and the win percentages are pre-programmed into the software.
Casino slot machines have Random Number Generators that are continuously generating combos, even when the slot machine is not being played.
Running concurrently with the random # generator of the casino slot machine game is the pay out rate per cent.
The pay out % controls how much the slot machine will pay, for example the payout percent might be 90%, which means the slot machine game will payout ninety per cent of all the wagers played, and the casino only gets to keep ten per cent.
This does not mean that for every time you bet 10 credits you will receive nine in return – where is the fun … exhilaration in that? Instead, the casino slot machine game will not payout for a little while, and then suddenly fire up a hot streak and you might hit a big jackpot prize.
The payoff %s will very likely vary between the differing games and a handful of the highly popular casinos, e.g. Golden Online Casino, which puts forth a cash payment of up to 95 per cent!
Therefore, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a few privileged winners. The casino only gets to keep a fairly small percent of all the stakes allotted.
The casino one armed bandit software controls each part of the machine, from the blinking lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which relates to the pictures on the reel.
