Kai-Yu Tsai has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 6.45, set at Ontario Championship 2024, puts him in the top 23.4% of the 129,321 people who have ever been ranked in the event, and 342nd in Chinese Taipei. Across 9 competitions since February 2023, he has put 109 official solves on the record across eight events.

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.
