Siyuan Liu (刘思源) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 2.08, set at Penn Cube Day Fall 2025, puts him in the top 1.3% of the 130,891 people who have ever been ranked in the event, and 145th in China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 12 competitions since October 2019, he has put 220 official solves on the record across six events. Solve to solve, his 3×3 times vary about 15% around a typical one; 88% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His Pyraminx best has come down from 4.68 in October 2019 to 2.08, a 56% improvement. Siyuan has entered twelve competitions, more competitions than 94% 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.
