3×3 · top 5.1% of 284,439 all-time · competing since June 2023 · 2023KHOO01
Christopher Khoo has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.10, set at Singapore Championship 2026, puts him in the top 5.1% of the 284,439 people who have ever been ranked in the event, and 138th in Singapore. Until May 2008, no official 3×3 solve in the world had been that fast. Across 10 competitions since June 2023, he has put 245 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 58% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 18.16 in June 2023 to 9.10, a 50% improvement. Christopher has entered ten competitions, more competitions than 92% 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.
