Chenghao Guo (国成浩)

Megaminx · top 2.2% of 34,786 all-time · competing since May 2016 · 2016GUOC01

Chenghao Guo (国成浩) has been competing for 10 years. His best event is the Megaminx: a personal-best single of 42.27, set at Zhengzhou Open 2024, puts him in the top 2.2% of the 34,786 people who have ever been ranked in the event, and 41st in China. Until August 2014, no official Megaminx solve in the world had been that fast. Across 23 competitions since May 2016, he has put 773 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 14% around a typical one; 77% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 11 DNFs. His 3×3 best has come down from 18.54 in May 2016 to 8.18, a 56% improvement. Chenghao has entered 23 competitions, more competitions than 97% 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.
