Modern casino slot games are controlled by computer software, and the winning %s are pre-programmed into the gaming software.
Casino slot machine games have RNGs which are eternally generating combinations, even when the slot machine game is not currently being played.
Running collectively with the random # generator of the casino slot machine game is the pay out percentage.
The payout % controls just how much the slot machine game will pay out, for e.g. the pay out per cent might be ninety percent, which means the one arm bandit will pay out ninety percent of all the bets played, and the casino only gets to keep 10 per cent.
This doesn’t imply that every time you bet 10 credits you will receive nine in return – where’s the fun and excitement in that? Instead, the casino one arm bandit just will not pay out for a bit, and then suddenly hit a hot streak and you might draw the big grand prize.
The payout %s will tend to vary between the alternate games and a couple of the highly popular casinos, e.g. Golden Online Casino, which hands out a payout of up to 95 percent!
This means that, in essence, the slot machine takes all the funds played into it and pays it out to several lucky winners. The casino only gets to keep a basically indistinct percent of all the odds made.
The casino slot software controls any part of the machine, from the flickering lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is put together by the RNG which associates with the pictures on the reel.
