Modern casino slot games are controlled by computer software, and the win percentages are preprogrammed into the game software.
Casino slot machine games have RNGs which are continually 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 payout per cent.
The payout percent controls how much the one-armed bandit will payout, for example the payout percentage may be ninety per cent, meaning the slot machine will pay 90% of all the bets played, … the casino only gets to keep 10 percent.
This does not mean that every time you bet 10 credits you will receive nine in return – where’s the fun and thrill 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 jackpot prize.
The profit percentages usually will vary between the differing games and several of the notably acclaimed casinos, e.g. Golden Online Casino, which puts forth a cash payment of up to ninety-five percentage!
Thus, in essence, the slot machine game takes all the cash played into it and pays it out to a few lucky winners. The casino only gets to keep a averagely small percent of all the gambles allocated.
The casino slot software controls every part of the machine, from the blinking lights to the rotating of the reels.
When you hit spin on the slot machine game, a combination is set up by the RNG which corresponds to the pictures on the reel.
