Chi-Jen Yin (尹啟任)

3×3 · top 6.3% of 284,439 all-time · competing since September 2022 · 2022YINC03

Chi-Jen Yin (尹啟任) has been competing for 4 years. His best event is the 3×3: a personal-best single of 9.57, set at Maru Cube Day Taiwan 2024, puts him in the top 6.3% of the 284,439 people who have ever been ranked in the event, and 375th in Chinese Taipei. Until November 2007, no official 3×3 solve in the world had been that fast. Across 7 competitions since September 2022, he has put 168 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 15.43 in September 2022 to 9.57, a 38% improvement. He has entered seven competitions, more competitions than 88% 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.
