Yancheng Liu (刘彦程)

3×3 one-handed · top 0.55% of 73,695 all-time · competing since June 2024 · 2024LIUY11

Yancheng Liu (刘彦程) has been competing for 2 years. His best event is the 3×3 one-handed: a personal-best single of 9.10, set at Cubing in Westerly RI 2026, puts him in the top 0.55% of the 73,695 people who have ever been ranked in the event, and 46th in China. Until November 2013, no official 3×3 one-handed solve in the world had been that fast. Across 31 competitions since June 2024, he has put 531 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 74% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 8.93 in June 2024 to 6.37, a 29% improvement. Yancheng has entered 31 competitions, more competitions than 98% 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.
