Yi-Kai Chen (陳奕暟)
2×2 · top 2.7% of 189,179 all-time · competing since December 2025 · 2025CHEY32
Yi-Kai Chen (陳奕暟) has been competing for 10 months. His best event is the 2×2: a personal-best single of 1.61, set at Maru Cube Day Taiwan 2026, puts him in the top 2.7% of the 189,179 people who have ever been ranked in the event, and 57th in Chinese Taipei. Until November 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since December 2025, he has put 79 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 17.02 in December 2025 to 8.26, a 51% improvement. He 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.
