Zixuan Xu (徐子轩) has been competing for 5 years. His best event is the 3×3: a personal-best single of 4.49, set at Zibo Open 2025, puts him in the top 0.046% of the 284,439 people who have ever been ranked in the event, and 33rd in China. Until May 2018, no official 3×3 solve in the world had been that fast. Across 31 competitions since April 2021, he has put 1,022 official solves on the record across six events.

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.
