Modern casino slot machine games are controlled by computer software, and the win percentages are pre-programmed into the game software.
Casino slot machines have RNGs which are eternally generating combos, even when the slot machine is not active.
Running collectively with the random # generator of the casino slot machine game is the payout rate per cent.
The payout per cent controls how much the one-armed bandit will pay out, for e.g. the pay percentage may be 90%, which means the slot game will payout 90% of all the stakes played, … the casino simply gets to keep 10 percent.
This does not mean that every time you bet 10 credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine game won’t payout for a bit, and then suddenly jump on a hot streak and you might hit a big top prize.
The payoff percentages will vary between the a variety of games and a handful of the notably favored casinos, e.g. Golden Online Casino, which puts forth a pay out of up to ninety-five %!
Hence, 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 fairly small per cent of all the bets made.
The casino one armed bandit software controls every part of the machine, from the blinking lights to the circulating of the reels.
When you hit spin on the slot machine, a combination is set up by the RNG which associates with the pictures on the reel.
