3×3 · top 1.5% of 284,439 all-time · competing since January 2019 · 2019NAKA02
Ryusei Nakabayashi (中林琉聖) has been competing for 8 years. His best event is the 3×3: a personal-best single of 7.11, set at Katano Summer 2025, puts him in the top 1.5% of the 284,439 people who have ever been ranked in the event, and 67th in Japan. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since January 2019, he has put 55 official solves on the record across one event. Solve to solve, his 3×3 times vary about 14% around a typical one; 71% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 9.36 in January 2019 to 7.11, a 24% improvement. Ryusei has entered four competitions, more competitions than 78% 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.
