Chengyinan Luo (罗骋一南) has been competing for 2 years. Her best event is the Pyraminx: a personal-best single of 2.49, set at Korea Open 2025, puts her in the top 2.2% of the 129,321 people who have ever been ranked in the event, and 260th in China. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 9 competitions since April 2024, she has put 100 official solves on the record across two events.

Chengyinan has entered nine competitions, more competitions than 91% 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.
