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 130,891 people who have ever been ranked in the event, and 10th in Hong Kong, China.

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.
