Jiayao Guo (郭家瑶) has been competing for 3 years. Her best event is the Skewb: a personal-best single of 1.44, set at Hefei Open 2025, puts her in the top 0.36% of the 73,281 people who have ever been ranked in the event, and 23rd in China. Until October 2015, no official Skewb solve in the world had been that fast. Across 32 competitions since December 2023, she has put 913 official solves on the record across six events. Solve to solve, her 3×3 times vary about 14% around a typical one; 68% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. Her 3×3 best has come down from 10.59 in December 2023 to 6.08, a 43% improvement. Jiayao has entered 32 competitions, more competitions than 98% 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.
