Jin Mochizuki (望月仁) has been competing for 17 years. His best event is the Pyraminx: a personal-best single of 2.37, set at Katano Milky Way 2024, puts him in the top 1.9% of the 129,321 people who have ever been ranked in the event, and 30th in Japan. Until April 2011, no official Pyraminx solve in the world had been that fast. Across 39 competitions since August 2009, he has put 792 official solves on the record across eight events.

His 3×3 best has come down from 21.38 in August 2009 to 9.93, a 54% improvement. Jin has entered 39 competitions, more competitions than 99% 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.
