Pyraminx · top 0.12% of 129,321 all-time · competing since April 2024 · 2024CAOB02

Bofu Cao (曹柏辅) has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 1.16, set at Yancheng Spring Open 2026, puts him in the top 0.12% of the 129,321 people who have ever been ranked in the event, and 13th in China. Until June 2018, no official Pyraminx solve in the world had been that fast. Across 9 competitions since April 2024, he has put 262 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 57% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 12.46 in April 2024 to 5.58, a 55% improvement. Bofu has entered nine competitions, more competitions than 91% 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.
