Guobiao Majiang

From Wikipedia, the free encyclopedia

Guóbiāo Májiàng (simplified Chinese: 国标麻将, literally National Standard Mahjong) is a rule of Mahjong founded by All-China Sports Federation in July 1998.

Features in the rule

There are exactly 4 hands for each Prevailing Wind, because Game Wind always changes after each round of 4 hands. So one match consists of exactly 16 hands.
According to player's tiles, situation of hand's completion etc., points called "fan" (番) is given. Any player can declare winning of the hand only if he/she has 8 or more points with his/her hand's completion.
Winner of a hand receives points from the other 3 players according to this system:
- If the winner completes the <var>x</var>-points hand with his/her draw of a tile, he/she receives (8+<var>x</var>) points from all the other 3 players.
- If the winner completes the <var>x</var>-points hand with a tile discarded by another player, he/she receives (8+<var>x</var>) points from the player having discarded the tile, and 8 points from each of the other 2 players.
There are no restriction of the last tile of hand completion because of discarded tiles. (There are restrictions in some rule, e.g. Japanese one.)
Positions of seats are changed between first and last half; i.e. beginning of the third(West) Prevailing Wind.
With meld of closed quad (暗槓, angang), all 4 tiles are placed faced down in front of the player. (What tile they are is not revealed). They are revealed at the end of the hand.
