[Game Rules]
1. Deal cards
A shuffled pack of 54 cards is dealt to three players. Each player is dealt 17 cards, with the last three remaining cards placed on the playing desk face down. These three cards cannot be seen before the landlord is determined.

2. Bid for position of landlord
All players take turns bidding for the position of landlord. If no one is willing to accept the position, the system once again deals cards and then all players bid for the landlord position, until the landlord is determined.

3. The first bidder
Generally speaking, the first bidder is randomly chosen by the system.

4. Outbid for the landlord position
A. After a player bids for the landlord position, others have only one chance to “outbid” in sequence for the position. The player becomes the landlord after he or she outbids for the position and others give up.
B. If no one outbids for the position, the bidding player becomes the landlord.
C. Each time when a player outbids for the position, the risk stakes double.
D. Players who gave up bidding for the position cannot outbid for the position either.

5. Raise the risk stakes
A. When the landlord is determined and receives the remaining three cards, he or she can opt whether or not to double the risk stakes.
B. The landlord needs to make a decision within the time limit and then await others to make their decisions within the time limit. Then the landlord begins to play the cards.

6. Play cards
The remaining three cards are shown to all players and then given to the landlord. The landlord begins playing cards first and then others play cards in counterclockwise order. Players can opt to pass or beat the prior hand. A game is over when a player has no cards remaining.
