Yichen Sheng (盛亦辰) has been competing for 3 years. His best event is the 3×3: a personal-best single of 5.27, set at UCSD TritoNxN 2026, puts him in the top 0.18% of the 284,439 people who have ever been ranked in the event, and 125th in the United States. Until April 2015, no official 3×3 solve in the world had been that fast. Across 20 competitions since June 2023, he has put 273 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 59% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 10.70 in June 2023 to 5.27, a 51% improvement. Yichen has entered 20 competitions, more competitions than 97% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
