2×2 · top 8.0% of 186,767 all-time · competing since February 2025 · 2025ITOK01

Kosuke Ito (伊藤広裕) has been competing for a year. His best event is the 2×2: a personal-best single of 2.40, set at Kanto Summer AM 2025, puts him in the top 8.0% of the 186,767 people who have ever been ranked in the event, and 107th in Japan. Until February 2008, no official 2×2 solve in the world had been that fast. Across 2 competitions since February 2025, he has put 18 official solves on the record across two events. His 3×3 best has come down from 16.22 in February 2025 to 10.99, a 32% improvement. Kosuke has entered two competitions.

The story so far

Competitions

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.
