Jiazhou Li (李佳洲) has been competing for 10 years. His best event is the 2×2: a personal-best single of 0.41, set at Beijing Winter 2026, puts him in the top 0.0011% of the 186,767 people who have ever been ranked in the event, and 2nd in China. Until October 2025, no official 2×2 solve in the world had been that fast. Across 51 competitions since May 2016, he has put 3,187 official solves on the record across 14 events.

The story so far

Competitions

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.
