From BIHUA Entertainment:
Play rule you sit at south, north player is your friend. East player and west player are opponents. First, there are four cards (spare 7, red hearts 7, flower 7 and black heart 7) on the desk, the remainder cards will distribute to four players. You are the first man to play. Only one card can be sent every time. The card sent to desk must follow the sequence of the cards on desk. However the two jokers can be sending to anywhere and they will replace the card, then the card replaced become to a dead card. If you have no card can be sent to the desk. The next player can send one needless card to you; you lost a chance to play.V.V. BTW. If you have a chance to send a card to the other, the dead card is recommended. When three players have use up all cards, the current game is over.
