Tan Yan Kai James has been competing for 2 years. His best event is the Skewb: a personal-best single of 1.51, set at Singapore Twist and Tips July 2026, puts him in the top 0.47% of the 73,281 people who have ever been ranked in the event, and 4th in Singapore. Until October 2015, no official Skewb solve in the world had been that fast. Across 14 competitions since March 2024, he has put 291 official solves on the record across six events.

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.
