Renjian Chen (陈仁键) has been competing for 10 years. His best event is the 3×3: a personal-best single of 8.05, set at Shenzhen Open 2024, puts him in the top 2.9% of the 284,439 people who have ever been ranked in the event, and 1,038th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 10 competitions since August 2016, he has put 237 official solves on the record across seven events.

His 3×3 best has come down from 12.82 in August 2016 to 8.05, a 37% improvement. Renjian has entered ten competitions, more competitions than 92% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
