Zhibo Jin (金智博) has been competing for 8 years. His best event is the 2×2: a personal-best single of 0.99, set at Glasgow Spring 2024, puts him in the top 0.54% of the 186,767 people who have ever been ranked in the event, and 54th in China. Until November 2008, no official 2×2 solve in the world had been that fast. Across 32 competitions since April 2018, he has put 1,296 official solves on the record across ten events.

His 2×2 best has come down from 4.74 in April 2018 to 0.99, a 79% improvement. Zhibo has entered 32 competitions, more competitions than 98% 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.
