13 Auto-Tables

Play on the brand new AMOS REXX fully automatic mahjong tables. 6 AMOS REXX and 7 Chinese automatic tables will be provided for players.


The tournament will use the World Riichi Championship 2015 rule set. This is a standardized rule set optimized for tournament play. You can download the rules here: World Riichi Championship Rules 2015.

It is not necessary for players to know how to score their hands, though highly recommended. Both English and Japanese are the official languages of the tournament and players must be able to converse in at least one of the languages.

The tournament capacity is 52 players, and this includes any invited pros and guests. Slots will be available on a first come basis. Registration assignment to another player is possible, however PML will not refund any ticket sales. If you wish to transfer your ticket to another player you must inform PML immediately.


8 hanchan, 30,000 starting points, 80 minutes per game.

Every player will play 8 hanchan, and the scores from each hanchan will be aggregated over the course of the tournament to determine placings. After 6 hanchan, the top 8 players will proceed to the upper bracket semifinals, and the lower 44 will proceed to the lower bracket semifinals. After the 7th hanchan, the top 4 players within the upper bracket will proceed to the upper bracket finals, and the lower 48 will proceed to the lower bracket finals.

For purposes of overall tournament placement, positions start with the upper bracket and continue into the lower bracket. For example, even if the 4th place player from the upper bracket has fewer points than the highest point player from the lower bracket, that player will be considered 4th for the tournament placements and the lower bracket player will receive 5th place.

At the end of the allotted 70 minutes, if a game has not ended, the current hand of the game may be completed, and the following hand may be started and played as the last hand of the game.
