Shaobo Cai (蔡邵博) has been competing for 2 years. His best event is the 3×3: a personal-best single of 6.77, set at Xuzhou Zenith 2026, puts him in the top 1.1% of the 284,439 people who have ever been ranked in the event, and 398th in China. Until November 2010, no official 3×3 solve in the world had been that fast. Across 5 competitions since March 2024, he has put 119 official solves on the record across seven events.

His 3×3 best has come down from 7.56 in March 2024 to 6.77, a 10% improvement. Shaobo has entered five competitions, more competitions than 83% 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.
