3×3 · top 7.7% of 288,433 all-time · competing since July 2014 · 2014ZHUC01
Congcong Zhu (朱聪聪) has been competing for 12 years. His best event is the 3×3: a personal-best single of 10.07, set at Xuzhou Open 2025, puts him in the top 7.7% of the 288,433 people who have ever been ranked in the event, and 3,058th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since July 2014, he has put 103 official solves on the record across four events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 97% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 13.08 in July 2014 to 10.07, a 23% improvement. Congcong has entered six competitions, more competitions than 86% 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.
