Khoo Yi Hao has been competing for 4 years. His best event is the Skewb: a personal-best single of 2.37, set at Penang Cube Masters 2025, puts him in the top 2.4% of the 73,281 people who have ever been ranked in the event, and 24th in Malaysia. Until February 2014, no official Skewb solve in the world had been that fast. Across 8 competitions since December 2022, he has put 247 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 63% of the 35,811 competitors with ten or more counted rounds. His Skewb best has come down from 15.27 in May 2023 to 2.37, an 84% improvement. Khoo has entered eight competitions, more competitions than 90% 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.
