Lo Tsz Ham (盧子涵) has been competing for a year. His best event is the Pyraminx: a personal-best single of 2.14, set at Singapore Augu-Skewb Day 2026, puts him in the top 1.4% of the 129,321 people who have ever been ranked in the event, and 10th in Hong Kong, China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 21 competitions since March 2025, he has put 403 official solves on the record across seven events.

His 2×2 best has come down from 7.13 in March 2025 to 2.20, a 69% improvement. Lo has entered 21 competitions, more competitions than 97% of everyone who has ever competed.

The story so far

Competitions

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.
