Xuan Liu (刘璇) has been competing for 10 years. His best event is the 4×4: a personal-best single of 27.79, set at Tokai Autumn 2026, puts him in the top 1.7% of the 85,040 people who have ever been ranked in the event, and 171st in China. Until April 2012, no official 4×4 solve in the world had been that fast. Across 43 competitions since November 2016, he has put 1,106 official solves on the record across 15 events.

His 3×3 best has come down from 18.22 in November 2016 to 8.00, a 56% improvement. Xuan has entered 43 competitions, more competitions than 99% 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.
