3×3 · top 9.7% of 288,433 all-time · competing since June 2025 · 2025JEON09
Isaac Jeong has been competing for a year. His best event is the 3×3: a personal-best single of 10.73, set at Michigan Mini 41 2026, puts him in the top 9.7% of the 288,433 people who have ever been ranked in the event, and 5,349th in the United States. Until August 2006, no official 3×3 solve in the world had been that fast. Across 8 competitions since June 2025, he has put 88 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 60% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 7 DNFs. His 3×3 best has come down from 31.53 in June 2025 to 10.73, a 66% improvement. Isaac has entered eight competitions, more competitions than 90% 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.
