Liam Highducheck has been competing for 11 years. His best event is the 2×2: a personal-best single of 0.75, set at NSW State Championship 2025, puts him in the top 0.17% of the 186,767 people who have ever been ranked in the event, and 34th in Australia. Until November 2011, no official 2×2 solve in the world had been that fast. Across 64 competitions since May 2015, he has put 3,381 official solves on the record across 17 events.

His 3×3 best has come down from 41.52 in May 2015 to 5.72, an 86% improvement. Liam has entered 64 competitions, more competitions than 99% 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.
