3×3 · top 3.8% of 284,439 all-time · competing since July 2022 · 2022RYUS01

SiChan Ryu (류시찬) has been competing for 4 years. His best event is the 3×3: a personal-best single of 8.51, set at Rubik's WCA World Championship 2023, puts him in the top 3.8% of the 284,439 people who have ever been ranked in the event, and 226th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 2 competitions since July 2022, he has put 20 official solves on the record across two events. His 3×3 best has come down from 9.89 in July 2022 to 8.51, a 14% improvement. SiChan has entered two competitions.

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.
