2×2 · top 8.0% of 186,767 all-time · competing since April 2024 · 2024SUNH04

Haozun Sun (孙浩尊) has been competing for 2 years. His best event is the 2×2: a personal-best single of 2.40, set at Zibo Open 2025, puts him in the top 8.0% of the 186,767 people who have ever been ranked in the event, and 1,152nd in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since April 2024, he has put 39 official solves on the record across four events. His Skewb best has come down from 9.36 in April 2024 to 4.89, a 48% improvement. Haozun 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.
