Ewen Chai has been competing for 11 years. His best event is the Pyraminx: a personal-best single of 2.80, set at Singapore Cubewerkz Open 2016, puts him in the top 3.0% of the 129,321 people who have ever been ranked in the event, and 41st in Singapore. Until October 2010, no official Pyraminx solve in the world had been that fast. Across 4 competitions since February 2016, he has put 92 official solves on the record across six events.

Ewen has entered four competitions, more competitions than 78% of everyone who has ever competed.

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.
