3×3 · top 9.6% of 288,433 all-time · competing since February 2023 · 2023GOLD05
Issac Goldberg has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.70, set at Colorado Cubing Weekend 2025, puts him in the top 9.6% of the 288,433 people who have ever been ranked in the event, and 5,301st in the United States. Until August 2006, no official 3×3 solve in the world had been that fast. Across 7 competitions since February 2023, he has put 173 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 31.55 in March 2023 to 10.70, a 66% improvement. Issac has entered seven competitions, more competitions than 88% 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.
