M.League 「Mリーグ」 is a professional mahjong team league. This is the first league where mahjong players receive a salary for playing games. Players are fielded from the various mahjong professional leagues. An M.League season consists of a number of regular season games followed by a playoff final. Each team is corporate sponsored, and thus they represent their respective companies. All league activity is hosted at the M.League Studio.

Format

The main format of the competition features a regular season and a post season. The basic format of the season varies in the number of hanchan played.

Current format

With eight teams, the regular season spans for 94 days for 188 hanchan. This grants 94 hanchan per team. After the final regular season day, the top six teams continue into the semifinal round, where they play 30 hanchan on a 15 day schedule. Into the final, the top four play another round of 16 hanchan on a 8 day schedule.

Rules and regulations

Game rules are indicated in the Official M-League Rules 「Mリーグの公式戦ルール」. All gameplay is in the form of hanchan using AMOS brand professional mahjong tables.

Game day

Every game day session includes two hanchan. Teams scheduled to play send one team member for each of the two hanchan. If desired, one player may play both hanchan.

Game rules

League rules comply with general riichi mahjong rules with special competitive settings. Starting score is 25,000 points; target score is 30,000 points; the uma is 「+30 / +10 / -10 / -30」.^[1]

Draft

Prior to each season, one day is set for team drafts. Teams select from a field of players among the different professional organizations. The inaugural draft was held on August 7, 2018. Naturally, every team made their player selections to fill their rosters in the inaugural draft. For subsequent drafts in later years, teams may opt to draft new players or otherwise pass on the opportunity. Currently, each team has rosters of four players.
