Jie-Kai Hsu (許杰凱) has been competing for 9 months. His best event is the 2×2: a personal-best single of 2.09, set at Taipei Cube Open 2026, puts him in the top 5.4% of the 186,767 people who have ever been ranked in the event, and 143rd in Chinese Taipei. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since November 2025, he has put 60 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 20.69 in November 2025 to 14.38, a 30% improvement. He has entered five competitions, more competitions than 83% 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.
