Ruihan Chen (陈睿涵)
3×3 one-handed · top 0.51% of 73,695 all-time · competing since August 2024 · 2024CHER13
Ruihan Chen (陈睿涵) has been competing for 2 years. His best event is the 3×3 one-handed: a personal-best single of 9.00, set at Xi'an New Year 2025, puts him in the top 0.51% of the 73,695 people who have ever been ranked in the event, and 42nd in China. Until November 2014, no official 3×3 one-handed solve in the world had been that fast. Across 10 competitions since August 2024, he has put 271 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one; 61% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 8.86 in August 2024 to 7.09, a 20% improvement. Ruihan has entered ten competitions, more competitions than 92% 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.
