Koh Zi Qian has been competing for 4 years. His best event is the Square-1: a personal-best single of 5.74, set at Cecil Singapore Playoffs 2024, puts him in the top 0.64% of the 25,272 people who have ever been ranked in the event, and 5th in Singapore. Until September 2017, no official Square-1 solve in the world had been that fast. Across 51 competitions since July 2022, he has put 1,563 official solves on the record across twelve events.

Best single per competition, Square-1. Faster is higher — the axis is the right way up.

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.
