Seung-Woo Song (송승우) has been competing for a year. His best event is the 2×2: a personal-best single of 1.61, set at Korea Open 2025, puts him in the top 2.6% of the 186,767 people who have ever been ranked in the event, and 77th in Republic of Korea. Until November 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since April 2025, he has put 131 official solves on the record across seven events.

He 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.
