3×3 · top 0.82% of 284,439 all-time · competing since February 2015 · 2015CHNG01

Jonathan Chng has been competing for 12 years. His best event is the 3×3: a personal-best single of 6.46, set at Singapore Mini 2019, puts him in the top 0.82% of the 284,439 people who have ever been ranked in the event, and 28th in Singapore. Until May 2011, no official 3×3 solve in the world had been that fast. Across 25 competitions since February 2015, he has put 1,022 official solves on the record across twelve events.

His 3×3 best has come down from 13.65 in February 2015 to 6.46, a 53% improvement. Jonathan has entered 25 competitions, more competitions than 98% 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.
