3×3 · top 6.2% of 288,433 all-time · competing since June 2025 · 2025OOTA01
Tsukasa Oota has been competing for a year. His best event is the 3×3: a personal-best single of 9.54, set at Otsu Biwako Winter 2026, puts him in the top 6.2% of the 288,433 people who have ever been ranked in the event, and 268th in Japan. Until February 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since June 2025, he has put 110 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 80% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 10.70 in June 2025 to 9.54, an 11% improvement. Tsukasa 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.
