Mah Jongg Tournament Platform — Updated June 2026
We built the tools tournament directors, league organizers, and instructors actually need — tournament registration, live scoring, table assignments, leaderboards, prize management, and push notifications — in one app, available on iOS, Android, and web.
• Directors manage tournaments via spreadsheets, email chains, and pen-and-paper scorecards
• No dedicated software exists for Mah Jongg — generic event tools miss critical game-specific features
• Instructors have no digital marketplace to reach students outside their local club
• Leagues have no way to track long-term standings, attendance, or prizes digitally
• Full tournament lifecycle: registration → check-in → table assignment → scoring → leaderboard → prizes
• Automated push notifications, room maps, borrowed set management, and real-time timers
• League management with RSVP, attendance history, and session-level standings
• Course marketplace for instructors to list and sell paid classes
Domain specificity
Built only for Mah Jongg — NMJL rules, flight logic, special hand tracking are native to the product, not bolt-ons.
Network effects
Every player on the platform is a potential referee for a new organizer's tournament. Growth is self-reinforcing.
Data advantage
As player histories accumulate, we build the richest Mah Jongg stats database in existence — a defensible asset competitors can't replicate quickly.
