Yu-Cheng Lin (林昱丞) has been competing for a year. His best event is the Clock: a personal-best single of 3.50, set at Taipei Cube Open 2026, puts him in the top 1.5% of the 32,048 people who have ever been ranked in the event, and 7th in Chinese Taipei. Until July 2018, no official Clock solve in the world had been that fast. Across 19 competitions since September 2024, he has put 295 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 65% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 25.49 in September 2024 to 11.29, a 56% improvement. He has entered 19 competitions, more competitions than 97% 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.
