Pai Gow Poker - Object of The Game

The object of the game is for a player to create two poker hands out of the seven cards in his hand: a five-card poker hand and a two-card poker hand. The five-card hand must rank higher than the two-card hand. The two-card hand is often called the hand "in front" or "on top", and the five-card hand is called the hand "behind" or "bottom", as they are placed that way in front of the player when he is done setting them.
