Hyunseo Kim (김현서)
2×2 · top 7.1% of 186,767 all-time · competing since May 2024 · 2024KIMH04
Hyunseo Kim (김현서) has been competing for 2 years. His best event is the 2×2: a personal-best single of 2.31, set at Korea Newcomers PM 2025, puts him in the top 7.1% of the 186,767 people who have ever been ranked in the event, and 200th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 8 competitions since May 2024, he has put 72 official solves on the record across five events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 22.75 in June 2024 to 12.57, a 45% improvement. Hyunseo has entered eight competitions, more competitions than 90% 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.
