3×3 blindfolded · top 5.2% of 12,178 all-time · competing since August 2017 · 2017ZHOU44

Yumeng Zhou (周雨萌) has been competing for 9 years. Her best event is the 3×3 blindfolded: a personal-best single of 33.99, set at China Championship 2019, puts her in the top 5.2% of the 12,178 people who have ever been ranked in the event, and 93rd in China. Until February 2010, no official 3×3 blindfolded solve in the world had been that fast. Across 11 competitions since August 2017, she has put 103 official solves on the record across eight events. Solve to solve, her 3×3 times vary about 9% around a typical one, an early reading from 6 counted rounds. Her 3×3 blindfolded best has come down from 2:59.59 in March 2018 to 33.99, an 81% improvement. Yumeng has entered eleven competitions, more competitions than 93% of everyone who has ever competed.

Best single per competition, 3×3 blindfolded. 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.
