Emma Chan Ern-Jia
2×2 · top 2.4% of 186,767 all-time · competing since July 2024 · 2024ERNJ01
Emma Chan Ern-Jia has been competing for 2 years. Her best event is the 2×2: a personal-best single of 1.55, set at Singapore Championship 2026, puts her in the top 2.4% of the 186,767 people who have ever been ranked in the event, and 2nd in Brunei. Until November 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since July 2024, she has put 129 official solves on the record across five events. Solve to solve, her 3×3 times vary about 15% around a typical one, an early reading from 8 counted rounds. That figure sets aside her 2 DNFs. Her 2×2 best has come down from 3.68 in July 2024 to 1.55, a 58% improvement. Emma has entered six competitions, more competitions than 86% of everyone who has ever competed.

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.
