Jacob Culleton Kaminski has been competing for a year. His best event is the 2×2: a personal-best single of 1.69, set at Gort-a Go Fast 2026, puts him in the top 3.0% of the 186,767 people who have ever been ranked in the event, and 56th in Ireland. Until February 2008, no official 2×2 solve in the world had been that fast. Across 11 competitions since November 2024, he has put 266 official solves on the record across five events.

His 3×3 best has come down from 24.88 in November 2024 to 15.38, a 38% improvement. Jacob has entered eleven competitions, more competitions than 93% 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.
