Yexin Zhang (张业鑫) has been competing for 13 years. His best event is the Megaminx: a personal-best single of 51.49, set at Wuhan Open 2021, puts him in the top 5.7% of the 34,786 people who have ever been ranked in the event, and 133rd in China. Until April 2010, no official Megaminx solve in the world had been that fast. Across 16 competitions since April 2013, he has put 472 official solves on the record across twelve 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.
