Modern casino slot machine games are controlled by a computer, and the win percentages are pre-programmed into the software.
Casino one armed bandits have Random Number Generators that are continuously generating combinations, even when the game is not currently being played.
Running concurrently with the random # generator of the casino slot machine is the payout %.
The payout % controls how much the slot machine will payout, for example the pay per cent could be ninety per cent, meaning the slot game will pay ninety percent of all the stakes played, … the casino simply gets to keep ten per cent.
This is not to say that every time you bet 10 credits you will receive nine in return – where is the fun and fascination in that? Instead, the casino slot machine won’t payout for a while, and then suddenly start up a hot streak and you might hit a big jackpot.
The pay out %s most likely will vary between the a variety of games and a handful of the most favored casinos, e.g. Golden Online Casino, which hands out a cash payment of up to ninety five per cent!
Hence, in essence, the slot machine game takes all the funds played into it and pays it out to a few chosen winners. The casino only gets to keep a relatively petite % of all the odds made.
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 one-armed bandit, a combination is put together by the RNG which corresponds to the pictures on the reel.
