Welcome to the 2024 Australian Riichi Mahjong Open
We would love to invite you to this year's Australian Riichi Mahjong Open, which will be held in Melbourne, Australia, over the weekend of December 7th and 8th 2024. This will be a qualifying competition for the 2025 World Riichi Championship in Tokyo, Japan, and the winner of ARMO will receive an invitation to attend this prestigious event. The Australian Riichi Mahjong Open is brought to you by the following organisations:
The Melbourne Mahjong Meetup Group is dedicated to those who are in Melbourne and would like to play the ancient game of mahjong and meet other players. If you are interested in playing some Cantonese/Japanese Mahjong on a regular basis, then this group is for you :)
The World Riichi Championship is an event run every three years in locations across the globe, bringing amateur and professional players to battle it out over the mahjong tiles for the title of World Riichi Champion.
The Australian Riichi Mahjong Association is Australia's national representative organisation for riichi mahjong. Their goals are to promote the sport of riichi mahjong in Australia, create networks between players, and to represent Australia on the world stage.
ARMO24 is now sold out!
Venue
Energetic, cosmopolitan, artsy, and sportsy: from Melbourne's exciting 24 hour CBD, to its exquisite suburban hubs, to its historical country towns, style and culture radiate in such abundance that it's not surprising the city is often voted the world's most livable. The 2024 Australian Riichi Mahjong Open will be held in Melbourne, at the Kensington Town Hall.
Built at the turn of the 20th century (1901), the Kensington Town Hall is a beautiful neoclassical building in Kensington, an inner suburb 4km north-west of the Melbourne CBD known for its village feel. Over its 123 years the Hall has hosted dances, war functions, boxing tournaments, political gatherings, a health centre, and in 2024 it will host the Australian Riichi Mahjong Open in its Main Hall.

Rules
Tournament Format
The tournament will consist of three stages totalling ten hanchan. Each hanchan will be limited to 85 minutes of play - after 85 minutes, players must finish the current hand, record their scores, and summon a referee to check and sign the scoresheet before they may leave the table.
Stage 1
All players (Group A) will compete over six hanchan in a round robin format.
Stage 2
The top 8 players will advance to Group B (semifinalists) and play two hanchan. Tables will be determined by their positions at the end of Stage 1 (1-2-7-8 and 3-4-5-6). Points will not carry over from Stage 1.
Players remaining in Group A will continue to compete for their position in that group.
Stage 3
The top two players from each table in Group B will advance to Group C (finalists) and play two hanchan. Points will not carry over from Stage 2. The winner will be crowned the champion of ARMO24!
Players remaining in Groups A and B will continue to compete for their position in their respective groups.

WRC Rules 2022 Edition
ARMO24 will utilise the standard 2022 edition of the World Riichi Championship ruleset, with no changes or optional modifications.
The WRC ruleset is the first international ruleset to be certified for competition play by authorities in Japan, Europe and the Americas. Since its introduction at the first World Riichi Championship in 2014, it has been updated and improved year over year to be a definitive guide to riichi mahjong play.
