Carmen Liu has been competing for 11 years. Her best event is the 3×3: a personal-best single of 9.49, set at Dutch Open 2019, puts her in the top 6.1% of the 284,439 people who have ever been ranked in the event, and 1st in Suriname. Until February 2008, no official 3×3 solve in the world had been that fast. Across 21 competitions since January 2016, she has put 435 official solves on the record across six events.

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.
