Chuan Luo (罗川) has been competing for 10 years. His best event is the 2×2: a personal-best single of 2.15, set at Nanchang Winter 2025, puts him in the top 5.9% of the 189,179 people who have ever been ranked in the event, and 828th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 2 competitions since April 2017, he has put 30 official solves on the record across three events. His 3×3 best has come down from 18.89 in April 2017 to 10.38, a 45% improvement. Chuan has entered two 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.
