The heart of the video poker machine is the Random Number Generator or RNG. An RNG is a software algorithm that ensures a truly random outcome of the game. The RNG is executed hundreds of times per second. The RNG has billions of possible outcomes for any given set of cards. Once the Start, Deal or Bet button is pressed (or the first coin is deposited), the outcome is determined regardless of the game or the number of coins wagered. You can always test poker games for free to make sure the games are fair.
