Game Description

Dou Dizhu (斗地主), literally "Fight the Landlord" is a card game playing by 3 players. It is one of the most popular card games played in China.

Dou Dizhu is played among three people with one pack of 54 cards, including the two jokers. Each player is dealt 17 cards face down and 20 cards for the landlord where the 3 extra cards will be hidden after the landord is confirmed.

The possible bids are 1, 2 and 3. Each player has a chance to bid. The higest bid will be the landord.

The next player for the highest bid's player can snatch to be the landlord.

The landlord plays first, and may play a single card or any legal combination.

Each subsequent player in anticlockwise order must either pass (play no card) or beat the previous play by playing a higher combination of the same number of cards and same type.

There are just two exceptions to this: a rocket can beat any combination,and a bomb can beat any combination except a higher bomb or rocket.

The play continues around the table for as many circuits as necessary until two consecutive players pass.
