Junkai Liu
2×2 · top 6.5% of 189,179 all-time · competing since June 2023 · 2023LIUJ09
Junkai Liu has been competing for 3 years. His best event is the 2×2: a personal-best single of 2.23, set at Western Ontario Winter 2026, puts him in the top 6.5% of the 189,179 people who have ever been ranked in the event, and 424th in Canada. Until February 2008, no official 2×2 solve in the world had been that fast. Across 13 competitions since June 2023, he has put 229 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one; 65% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 3 DNFs. His 3×3 best has come down from 20.86 in June 2023 to 11.03, a 47% improvement. Junkai has entered 13 competitions, more competitions than 94% 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.
