3×3 · top 1.8% of 284,439 all-time · competing since May 2024 · 2024CAOZ02

Zihan Cao (曹芓涵) has been competing for 2 years. His best event is the 3×3: a personal-best single of 7.34, set at Zhengzhou Summer III 2025, puts him in the top 1.8% of the 284,439 people who have ever been ranked in the event, and 621st in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since May 2024, he has put 70 official solves on the record across three events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 7 counted rounds. His 3×3 best has come down from 8.68 in May 2024 to 7.34, a 15% improvement. Zihan has entered four competitions, more competitions than 78% 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.
