Chen-Yu Kuo (郭鎮瑀) has been competing for 9 years. His best event is the 2×2: a personal-best single of 2.21, set at Maru Cube Day 2019, puts him in the top 6.3% of the 186,767 people who have ever been ranked in the event, and 168th in Chinese Taipei. Until February 2008, no official 2×2 solve in the world had been that fast. Across 9 competitions since June 2017, he has put 228 official solves on the record across seven events.

His 3×3 best has come down from 15.42 in June 2017 to 9.69, a 37% improvement. He has entered nine competitions, more competitions than 91% of everyone who has ever competed.

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.
