Jiechun Lin (林洁纯) has been competing for 10 years. Her best event is the Skewb: a personal-best single of 2.23, set at Guangzhou Special 2026, puts her in the top 2.0% of the 74,164 people who have ever been ranked in the event, and 101st in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 23 competitions since August 2016, she has put 350 official solves on the record across seven events.

Her Skewb best has come down from 4.64 in June 2019 to 2.23, a 52% improvement. Jiechun has entered 23 competitions, more competitions than 97% of everyone who has ever competed.

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.
