Hwang Seung Jun has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.16, set at Seoul Spring 2026, puts him in the top 5.2% of the 284,439 people who have ever been ranked in the event, and 309th in Republic of Korea. Until May 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since April 2023, he has put 68 official solves on the record across six events.

Hwang has entered five competitions, more competitions than 83% 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.
