Create a free account to set up your own league, or join one with a code from its owner.
Configurable scoring
Set your own Starting/Return Points, Uma, and optional Oka per league. The math is done for you.
Flexible ranking
Owners pick the Official Ranking Metric (Average LP, Total LP, 1st Place Rate, and more) and a Minimum Games requirement.
Provisional vs. Qualified
New players show up and play right away, but only count toward Official Rank once they've met the league's minimum games.
Shareable join codes
Every league gets a short code and link members can use to request to join. No manual invites required.
Audited approvals
Every submission, correction, approval, and rejection is logged, so standings stay trustworthy.
Play with anyone
Track results with friends who haven't registered yet using guest players, then let them claim their history later.
Beyond Riichi
Run a league for Chinese Official or Hong Kong Mahjong, not just Riichi.
