Marcus Lai (賴卓希)
3×3 · top 5.5% of 288,433 all-time · competing since August 2025 · 2025LAIM02
Marcus Lai (賴卓希) has been competing for a year. His best event is the 3×3: a personal-best single of 9.26, set at Odd Day in Hong Kong 2026, puts him in the top 5.5% of the 288,433 people who have ever been ranked in the event, and 163rd in Hong Kong, China. Until February 2008, no official 3×3 solve in the world had been that fast. Across 12 competitions since August 2025, he has put 218 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 53% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 2×2 best has come down from 3.86 in September 2025 to 2.33, a 40% improvement. Marcus 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.
