Ruiyin Chen (陈睿尹)

Clock · top 2.0% of 32,048 all-time · competing since July 2018 · 2018CHER09

Ruiyin Chen (陈睿尹) has been competing for 8 years. His best event is the Clock: a personal-best single of 3.80, set at Xi'an Open 2023, puts him in the top 2.0% of the 32,048 people who have ever been ranked in the event, and 28th in China. Until June 2015, no official Clock solve in the world had been that fast. Across 4 competitions since July 2018, he has put 56 official solves on the record across five events. His Pyraminx best has come down from 8.65 in July 2018 to 3.09, a 64% improvement. Ruiyin has entered four competitions, more competitions than 78% 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.
