Jin-Han Guo (郭景翰) has been competing for 15 years. His best event is the Pyraminx: a personal-best single of 3.29, set at Dream One Cube Open 2019, puts him in the top 4.6% of the 129,321 people who have ever been ranked in the event, and 72nd in Chinese Taipei. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 13 competitions since August 2011, he has put 287 official solves on the record across 14 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.
