Ryuichi Hayase (早瀬龍一)

2×2 · top 6.9% of 186,767 all-time · competing since January 2024 · 2024HAYA02

Ryuichi Hayase (早瀬龍一) has been competing for 3 years. His best event is the 2×2: a personal-best single of 2.28, set at Tokyo Spring 2026, puts him in the top 6.9% of the 186,767 people who have ever been ranked in the event, and 91st in Japan. Until February 2008, no official 2×2 solve in the world had been that fast. Across 17 competitions since January 2024, he has put 153 official solves on the record across 14 events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 67% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 12.75 in April 2025 to 11.29, an 11% improvement. Ryuichi has entered 17 competitions, more competitions than 96% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
