Mahjong Competition Rules
Mahjong Competition Rules , also known as Competition Mahjong and Guóbiāo Májiàng, is an international standard of rules and scoring criteria for mahjong founded by the All-China Sports Federation in July 1998 and supported by some mahjong societies, mostly in Asia. Many tournaments have adopted this standard and some mahjong societies exclusively use this scoring system for all play. It is characterised by dozens of possible combinations and a rather complex and inventive set of patterns. In effect, it mixes the scoring rules of several different mahjong variations. The game play is otherwise quite similar to Old Hong Kong Mahjong.
Main features
- There are exactly 4 hands for each Prevalent wind, because the Seat wind always changes after each round of 4 hands. Thus one match consists of exactly 16 hands.
- Points called "fan" are given according to factors such as the tiles a player has or how complete a player's hand is. Any player can declare a winning hand only if he has 8 or more points with his hand's completion.
- The winner of a hand receives points from the other 3 players as follows:
- *If the winner completes the x-points hand on a self-draw, he receives points from each of the other three players.
- *If the winner completes the x-points hand off a tile discarded by another player, he receives points from the player having discarded the tile, and 8 points from each of the other two players.
- There are no restrictions on completing a hand using discarded tiles.
- Positions of seats are changed every 4 hands—i.e., at the beginning of each new prevailing wind.
- When a "Concealed Kong" is obtained, all four tiles are placed faced down in front of the player and are not revealed until the end of the hand.
- There is no dead wall.
