Chenhao Sun (孙晨皓)

3×3 blindfolded · top 2.6% of 12,178 all-time · competing since October 2018 · 2018SUNC02

Chenhao Sun (孙晨皓) has been competing for 8 years. His best event is the 3×3 blindfolded: a personal-best single of 23.96, set at Kew Clock Clash 2024, puts him in the top 2.6% of the 12,178 people who have ever been ranked in the event, and 39th in China. Until June 2013, no official 3×3 blindfolded solve in the world had been that fast. Across 34 competitions since October 2018, he has put 1,108 official solves on the record across 17 events. Solve to solve, his 3×3 times vary about 15% around a typical one; 79% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 9 DNFs. His 3×3 best has come down from 20.63 in October 2018 to 12.22, a 41% improvement. Chenhao has entered 34 competitions, more competitions than 98% 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.
