3×3 · top 1.3% of 284,439 all-time · competing since February 2019 · 2019MUJI01
Si Mujin (시무진) has been competing for 8 years. His best event is the 3×3: a personal-best single of 6.96, set at Rubik's WCA World Championship 2023, puts him in the top 1.3% of the 284,439 people who have ever been ranked in the event, and 78th in Republic of Korea. Until November 2010, no official 3×3 solve in the world had been that fast. Across 2 competitions since February 2019, he has put 27 official solves on the record across two events. His 3×3 best has come down from 9.98 in February 2019 to 6.96, a 30% improvement. Si has entered two 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.
