Shibo Yu (于士博) has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 2.88, set at Beijing Summer 2025, puts him in the top 3.2% of the 129,321 people who have ever been ranked in the event, and 379th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 3 competitions since March 2024, he has put 50 official solves on the record across five events. His Pyraminx best has come down from 4.82 in March 2024 to 2.88, a 40% improvement. Shibo has entered three competitions, more competitions than 69% 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.
