Yunbo Gu (古韵博) has been competing for 3 years. His best event is the 3×3: a personal-best single of 5.85, set at Nanchang Summer 2026, puts him in the top 0.4% of the 284,439 people who have ever been ranked in the event, and 156th in China. Until June 2011, no official 3×3 solve in the world had been that fast. Across 5 competitions since December 2023, he has put 90 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 70% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 10.68 in December 2023 to 5.85, a 45% improvement. Yunbo has entered five competitions, more competitions than 83% 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.
