3×3 · top 3.0% of 284,439 all-time · competing since April 2019 · 2019YUJI01

Jia Yu (于嘉) has been competing for 7 years. His best event is the 3×3: a personal-best single of 8.10, set at Yancheng Open 2025, puts him in the top 3.0% of the 284,439 people who have ever been ranked in the event, and 1,073rd in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since April 2019, he has put 28 official solves on the record across two events. His 3×3 best has come down from 46.64 in April 2019 to 8.10, an 83% improvement. Jia 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.
