The middle row has 5 cards and has to be a higher ranking hand than the top hand. Of the 3 rows, the top row is made up of 3 cards, and can be 3 of a kind, 1 pair, or high card. When all 5 rounds are complete, you will have your 13 card completed hand, comprising 2 rows of 5 cards, and 1 row of 3 cards. Your opponents do not see your disposed cards. Initially you are dealt 5 cards each, all face up, then another 4 rounds where you are dealt 3 cards, all face down, and you must play 2 of those cards, and dispose of 1. In a hand there are 5 rounds of play, opposed to the standard 9 hands in regular Chinese poker games.
