Runzheng Chen
Pyraminx · top 6.6% of 130,891 all-time · competing since August 2025 · 2025CHER10
Runzheng Chen has been competing for a year. His best event is the Pyraminx: a personal-best single of 3.77, set at Head to UBC Morning 2026, puts him in the top 6.6% of the 130,891 people who have ever been ranked in the event, and 798th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since August 2025, he has put 87 official solves on the record across four events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 32.50 in August 2025 to 21.14, a 35% improvement. Runzheng has entered seven competitions, more competitions than 88% 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.
