Charlie Zhao

3×3 · top 1.7% of 284,439 all-time · competing since August 2023 · 2023ZHAO16

Charlie Zhao has been competing for 3 years. His best event is the 3×3: a personal-best single of 7.28, set at Waterloo Winter 2025, puts him in the top 1.7% of the 284,439 people who have ever been ranked in the event, and 172nd in Canada. Until July 2008, no official 3×3 solve in the world had been that fast. Across 12 competitions since August 2023, he has put 188 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 62% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 9.44 in August 2023 to 7.28, a 23% improvement. Charlie has entered twelve competitions, more competitions than 94% of everyone who has ever competed.

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.
