Edward Zeng has been competing for 9 years. His best event is the 2×2: a personal-best single of 1.41, set at Berkeley Summer 2023, puts him in the top 1.8% of the 186,767 people who have ever been ranked in the event, and 111th in Canada. Until November 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since January 2018, he has put 407 official solves on the record across 15 events.

His 3×3 best has come down from 23.40 in January 2018 to 10.70, a 54% improvement. Edward has entered 15 competitions, more competitions than 95% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
