Jihu Mun (문지후) has been competing for 12 years. His best event is the 3×3 one-handed: a personal-best single of 9.01, set at UCSD Winter 2024, puts him in the top 0.51% of the 73,695 people who have ever been ranked in the event, and 79th in the United States. Until November 2014, no official 3×3 one-handed solve in the world had been that fast. Across 60 competitions since June 2014, he has put 2,407 official solves on the record across 17 events.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
