Chengjun Chen (陈诚骏)

3×3 one-handed · top 1.6% of 74,621 all-time · competing since July 2024 · 2024CHEC02

Chengjun Chen (陈诚骏) has been competing for 2 years. His best event is the 3×3 one-handed: a personal-best single of 10.76, set at Guangzhou Small Cubes 2025, puts him in the top 1.6% of the 74,621 people who have ever been ranked in the event, and 143rd in China. Until July 2011, no official 3×3 one-handed solve in the world had been that fast. Across 8 competitions since July 2024, he has put 236 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 62% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 8.87 in July 2024 to 7.98, a 10% improvement. Chengjun has entered eight competitions, more competitions than 90% 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.
