Dou Di Zhu is a free card game application developed by LuoJiang for Android devices. The game is a poker game for three players, where one player plays alone as the "landlord," and the other two players form a team. The objective of the landlord is to be the first to play all of their cards in valid combinations, while the team wins if any one of them manages to play all their cards before the landlord.

The game uses a 54-card pack, including two jokers, red, and black. The auction is used to determine which player will be the landlord, and play alone against the other two. The landlord plays first, and may play a single card or any legal combination. The play continues around the table for as many circuits as necessary until two consecutive players pass. There are thirteen types of combinations that can be played, and the scoring is based on the number of bombs or rockets played and the order in which players run out of cards.
