Meng-Hsu Tsai (蔡孟旭) has been competing for 10 months. His best event is the 3×3: a personal-best single of 10.41, set at Shin Kong Cube Open - Kaohsiung 2026, puts him in the top 8.7% of the 288,433 people who have ever been ranked in the event, and 539th in Chinese Taipei. Until February 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since December 2025, he has put 24 official solves on the record across one event.

He has entered four competitions, more competitions than 78% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
