Aidan Xu

Pyraminx · top 1.1% of 129,321 all-time · competing since September 2022 · 2022XUAI02

Aidan Xu has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 2.00, set at Brantford Fall 2025, puts him in the top 1.1% of the 129,321 people who have ever been ranked in the event, and 41st in Canada. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 27 competitions since September 2022, he has put 619 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 14% around a typical one; 75% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 21.19 in September 2022 to 10.20, a 52% improvement. Aidan has entered 27 competitions, more competitions than 98% 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.
