Yusi Cheng (成于思) has been competing for 9 years. His best event is the 3×3: a personal-best single of 10.82, set at Changsha Open 2023, puts him in the top 10.0% of the 288,433 people who have ever been ranked in the event, and 3,975th in China. Until August 2006, no official 3×3 solve in the world had been that fast. Across 4 competitions since March 2018, he has put 74 official solves on the record across six events.

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.
