Han Do Hyun (한도현) has been competing for 9 years. His best event is the 3×3: a personal-best single of 10.35, set at Korea Open 2026, puts him in the top 8.5% of the 284,439 people who have ever been ranked in the event, and 487th in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since January 2018, he has put 164 official solves on the record across 13 events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 1:01.61 in January 2018 to 10.35, an 83% improvement. Han 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.
