Rank

Our system is inspired by the Elo-style ranking models used by organizations like the USTA and DUPR. Players move up based on the value of their wins, including victories over more advanced players. Rankings also account for inactivity through decay to ensure accuracy over time.

Tournament Highlights

Meet the masterminds behind the American Mahjong Ranking Authority—Bethany Factor and Amanda Wolsey.

These two Fort Worth mom-epreneurs turned their deep love for the game into a movement.

Amanda Wolsey has been studying the intricacies of Mahjong since 2010 and sharing her expertise as a teacher through her business, @the.mahjclub , since 2022. Her foundation is built on years of practice and passion.

Bethany Factor learned the game more recently but her competitive spirit (thanks to a background in tennis!) ignited a new vision. She teamed up with Amanda to open @themahjclubhouse -Fort Worth’s premier Mahjong playing boutique.

Together, they noticed a missing piece in the American Mahjong community: a structured way to rank and track competitive play. Drawing from Bethany’s tennis ranking experience and Amanda’s deep Mahjong roots, they decided to build the solution themselves.

Say hello to AMR—born in Texas, built for players everywhere.
