Roy Byun
2×2 · top 2.4% of 186,767 all-time · competing since August 2022 · 2022BYUN03
Roy Byun has been competing for 4 years. His best event is the 2×2: a personal-best single of 1.55, set at Cube Against Cancer - Orange County 2025, puts him in the top 2.4% of the 186,767 people who have ever been ranked in the event, and 934th in the United States. Until November 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since August 2022, he has put 343 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 15% around a typical one; 80% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 8 DNFs. His 3×3 best has come down from 20.67 in August 2022 to 9.29, a 55% improvement. Roy has entered 15 competitions, more competitions than 95% 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.
