Modern casino Slots are controlled by computer software, and the win %s are pre-programmed into the game software.
Casino slot games have Random Number Generators that are continually generating combos, even when the game is not currently being played.
Running concurrently with the RNG of the casino slot machine is the pay out percentage.
The pay out per cent controls just how much the one-armed bandit will pay, for eg the pay out percentage may be 90%, meaning the one arm bandit will pay ninety percent of all the stakes played, … the casino gets to keep 10%.
This does not imply that every time you bet 10 credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine game won’t payout for a bit, and then suddenly hit a hot streak and you might hit a big jackpot prize.
The payout percentages most likely will vary between the a variety of games and just a few of the notably favored casinos, for e.g Golden Online Casino, which hands out a payout rate of up to ninety five percentage!
This means that, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to several fortunate winners. The casino only gets to keep a basically indistinct percent of all the odds put out.
The casino slot machine software controls any part of the machine, from the flashing lights to the rotating of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which is linked to the pictures on the reel.
