Riki Osawa has been competing for 12 years. His best event is the 3×3: a personal-best single of 10.07, set at San Diego Summer Splash 2015, puts him in the top 7.7% of the 284,439 people who have ever been ranked in the event, and 4,218th in the United States. Until May 2007, no official 3×3 solve in the world had been that fast. Across 12 competitions since November 2014, he has put 283 official solves on the record across ten events.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
