Jiawei Zhang (张嘉伟) has been competing for 8 years. His best event is the Skewb: a personal-best single of 1.88, set at Hangzhou Winter 2025, puts him in the top 1.1% of the 73,281 people who have ever been ranked in the event, and 45th in China. Until December 2014, no official Skewb solve in the world had been that fast. Across 7 competitions since October 2018, he has put 175 official solves on the record across eight events.

His Skewb best has come down from 2.64 in October 2018 to 1.88, a 29% improvement. Jiawei has entered seven competitions, more competitions than 88% 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.
