Yu-Hsuan Chang (張祐瑄) has been competing for 13 years. His best event is the Skewb: a personal-best single of 2.20, set at Malaysia Cube Championship 2019, puts him in the top 1.9% of the 73,281 people who have ever been ranked in the event, and 19th in Chinese Taipei. Until February 2014, no official Skewb solve in the world had been that fast. Across 110 competitions since August 2013, he has put 3,224 official solves on the record across 14 events.

Best single per competition, Skewb. Faster is higher — the axis is the right way up.

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.
