Description
Good afternoon!
We are pleased to announce the first season of a new regular individual online Riichi Mahjong league.
The league will be held on the tenhou.net platform.
There are no rank restrictions, but detailed participation rules are outlined in the league regulations (see the "Participation Restrictions" section).
The estimated duration of the season is 3 months.
The season will consist of 2 stages:
Main Stage (all players, 24 hanchans) – 6 weeks.
Playoffs (16 players, 6+6+6 hanchans) – 6 weeks.
Stage Details:
Main Stage consists of 2 rounds, each lasting 3 weeks.
In each round, participants are divided into tables of 4 players.
Each participant joins 4 tables simultaneously.
Tables may play in any order—players arrange the date and time among themselves.
Each table plays 3 hanchans.
After two rounds, each participant will have played a total of 24 hanchans.
The top 16 players advance to the playoffs.
Playoffs:
The 16 qualifying players are divided into 4 quarterfinal tables (4 players each).
Scores from the main stage are carried over to the quarterfinals divided by 2.
Each table plays 6 hanchans.
The final score is the sum of points from the 6 hanchans + carried-over points from the main stage.
The top 2 players from each table advance to the semifinals.
The semifinals and finals follow the same format.
The winner of the final becomes the league champion for this season.
Hanchans are played according to RRC rules.
