Sichen Li (李思辰) has been competing for 3 years. His best event is the 3×3: a personal-best single of 8.48, set at Beijing Summer 2025, puts him in the top 3.7% of the 284,439 people who have ever been ranked in the event, and 1,395th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since November 2023, he has put 96 official solves on the record across ten 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.
