Players will play out 9 [[hanchan]].  They will be subdivided into Groups A and Group B.  Out of the total participant count, the top 32 will proceed into an elimination tournament.  At each stage, they will play 2 hanchan.  Tournament days 1 and 2 will have 4 hanchan each, while day 3 will have the 9th hanchan immediately followed by the first two stages of the elimination tournament.  Day 4 will include the semifinal and the final.

Players who did not make it into the top 32 had the option to play in a four game [[tonpuusen]] side event.  In addition, the Japanese players gave mahjong strategy lessons for a second side event.

As there is no official rankings by country available, the table below is presenting the best, average, median and worst scores, as well as a composite score (the average of all four). Players placing equally with another player are ranked as a half-rank lower, in order to maintain statistical comparability.

Notes:
South Korea and Switzerland did have registered participants that had to desist. Total attendance is thus 224 players from 25 countries (not 27).

Tournament format

Players will play out 9 hanchan. They will be subdivided into Groups A and Group B. Out of the total participant count, the top 32 will proceed into an elimination tournament. At each stage, they will play 2 hanchan. Tournament days 1 and 2 will have 4 hanchan each, while day 3 will have the 9th hanchan immediately followed by the first two stages of the elimination tournament. Day 4 will include the semifinal and the final.

Players who did not make it into the top 32 had the option to play in a four game tonpuusen side event. In addition, the Japanese players gave mahjong strategy lessons for a second side event.
