Ikoi Yamaki

3×3 · top 5.8% of 284,439 all-time · competing since September 2023 · 2023YAMA15

Ikoi Yamaki has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.37, set at Las Piñas Speedcubing Open 2024, puts him in the top 5.8% of the 284,439 people who have ever been ranked in the event, and 245th in Japan. Until February 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since September 2023, he has put 112 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 70% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.58 in September 2023 to 9.37, a 36% improvement. Ikoi has entered six competitions, more competitions than 86% of everyone who has ever competed.

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.
