Junhyeok Choi (최준혁) has been competing for 4 years. His best event is the 4×4: a personal-best single of 27.87, set at Seoul Summer 2026, puts him in the top 1.7% of the 83,917 people who have ever been ranked in the event, and 44th in Republic of Korea. Until April 2012, no official 4×4 solve in the world had been that fast. Across 17 competitions since May 2022, he has put 355 official solves on the record across twelve events.

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.
