GMT Tournament Rules

Tournament Rounds:

The Tournament consists of 4 rounds by 50 minutes each (except NMJL(MJMP) – 3 rounds or 1 hour each) and 10 minutes break between each round

Table Details:

Min points:	Hong Kong – 8, Taiwanese – 6, MCR – 8, NMJL(MJMP) – 0, Riichi - 1 yaku
Rated:	No
Flowers:	Hong Kong, Taiwanese, MCR, NMJL(MJMP) – Yes; RCR - No
Game Helper:	Yes

Registration & Check-in:

The registration closes 30 minutes before the tournament starting time. The registered players are required to check-in (login to the game) 15 minutes before the tournament starts.
Any player that won't play at the tournament for more than 26 minutes in one round may be disqualified and may not be able to join the next round of the competition. Also your entry fee will not be refunded and your GMTR tournament standings will contain 0 points for the corresponding tournament style.

Scoring:

At the end of each round, each player will receive a "table point" according to the score. The table point assignment is as follows:

Highest score: 4 pts
2nd highest score: 2 pts
3rd highest score: 1 pts
Lowest score: 0 pt

If two (or more) players tie for a position, they share equally the added points. For example: 0.5 points each (half of 1 + 0) for two players sharing the last position. Tournament rankings are determined through table points. Players with more table points in a game earn higher placement in the tournament. If a tie in table points occurs between players, the player with the highest overall score will be ranked higher. In the unlikely event that two players are tied in both table points AND overall score, the player that won more hands in the game will be ranked higher.

Tournament entry fee is 500 Golden Coins ($5). Mahjong Time subscribers/members receive 400 Golden Coins back to their account after successful completion of the tournament.
