Isaac Yuen Xi Sheng

3×3 · top 3.8% of 284,439 all-time · competing since November 2019 · 2019SHEN29

Isaac Yuen Xi Sheng has been competing for 7 years. His best event is the 3×3: a personal-best single of 8.51, set at Yong Jun KL Speedcubing 2023, puts him in the top 3.8% of the 284,439 people who have ever been ranked in the event, and 193rd in Malaysia. Until July 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since November 2019, he has put 70 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 10.51 in November 2019 to 8.51, a 19% improvement. Isaac has entered three competitions, more competitions than 69% of everyone who has ever competed.

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.
