Kuah Seng Jee has been competing for 4 years. His best event is the Skewb: a personal-best single of 2.08, set at Singapore Polytechnic Sprint 2026, puts him in the top 1.6% of the 73,281 people who have ever been ranked in the event, and 11th in Singapore. Until December 2014, no official Skewb solve in the world had been that fast. Across 14 competitions since December 2022, he has put 253 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. His Skewb best has come down from 7.70 in June 2023 to 2.08, a 73% improvement. Kuah has entered 14 competitions, more competitions than 95% 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.
