Leï Kobayashi has been competing for 4 years. His best event is the 3×3: a personal-best single of 9.21, set at Tigery Open 2026, puts him in the top 5.4% of the 284,439 people who have ever been ranked in the event, and 225th in Japan. Until February 2008, no official 3×3 solve in the world had been that fast. Across 12 competitions since April 2022, he has put 214 official solves on the record across six events.

His 3×3 best has come down from 22.76 in April 2022 to 9.21, a 60% improvement. He has entered twelve competitions, more competitions than 94% 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.
