3×3 · top 8.7% of 288,433 all-time · competing since December 2023 · 2023KIMC08
Chan Yu Kim (김찬유) has been competing for 3 years. His best event is the 3×3: a personal-best single of 10.39, set at NxN in Hanoi 2025, puts him in the top 8.7% of the 288,433 people who have ever been ranked in the event, and 503rd in Republic of Korea. Until February 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since December 2023, he has put 198 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 2 DNFs. His 2×2 best has come down from 5.11 in December 2023 to 2.48, a 51% improvement. Chan 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.
