3×3 · top 1.3% of 284,439 all-time · competing since November 2021 · 2021ZHOU19
Anna Zhou has been competing for 5 years. Her best event is the 3×3: a personal-best single of 6.94, set at Rubik's WCA World Championship 2025, puts her in the top 1.3% of the 284,439 people who have ever been ranked in the event, and 768th in the United States. Until November 2010, no official 3×3 solve in the world had been that fast. Across 30 competitions since November 2021, she has put 879 official solves on the record across six events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 71% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 9.30 in November 2021 to 6.94, a 25% improvement. Anna has entered 30 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.
