Isaac Chung has been competing for a year. His best event is the 3×3: a personal-best single of 10.25, set at North-East Melbourne March Saturday 2026, puts him in the top 8.2% of the 284,439 people who have ever been ranked in the event, and 744th in Australia. Until May 2007, no official 3×3 solve in the world had been that fast. Across 9 competitions since May 2025, he has put 189 official solves on the record across seven events.

His 3×3 best has come down from 20.40 in May 2025 to 10.25, a 50% improvement. Isaac has entered nine competitions, more competitions than 91% 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.
