Ronn Tan Zhi Yoong
Pyraminx · top 6.6% of 130,891 all-time · competing since June 2019 · 2019YOON03
Ronn Tan Zhi Yoong has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 3.77, set at One Shamelin Cube Open 2025, puts him in the top 6.6% of the 130,891 people who have ever been ranked in the event, and 121st in Malaysia. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 8 competitions since June 2019, he has put 283 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 95% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 45.38 in June 2019 to 11.25, a 75% improvement. Ronn 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.
