Li Chak Lam (李澤霖) has been competing for 4 years. His best event is the 3×3: a personal-best single of 7.05, set at Hong Kong Cube Day 2025, puts him in the top 1.4% of the 284,439 people who have ever been ranked in the event, and 30th in Hong Kong, China. Until November 2010, no official 3×3 solve in the world had been that fast. Across 6 competitions since March 2023, he has put 56 official solves on the record across five events.

Li has entered six competitions, more competitions than 86% 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.
