Modern casino slot machine games are controlled by computer chips and software, and the winning percentages are pre-programmed into the computer software.
Casino slot machines have Random # Generators that are continuously generating combinations, even when the slot machine game is not currently being played.
Running in unison with the Random Number Generator of the casino slot machine game is the pay out rate per cent.
The pay out percent controls how much the slot machine game will pay out, for e.g. the pay per cent may be ninety per cent, which means the slot game will pay out ninety percent of all the stakes played, … the casino only gets to keep 10%.
This is not to say that each time you bet 10 credits you will receive nine in return – where is the fun and exhilaration in that? Instead, the casino one arm bandit will not payout for a bit, and then suddenly hit a hot streak and you might catch the big top prize.
The payoff %s most likely will vary between the differing games and just a few of the most famous casinos, like Golden Online Casino, which puts forth a payout of up to 95 percentage!
So, in essence, the slot machine takes all the currency played into it and pays it out to some lucky winners. The casino only gets to keep a generally tiny per cent of all the plays put out.
The casino slot software controls every single part of the machine, from the dazzling lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is produced by the RNG which associates with the pictures on the reel.
