Carol Chai has been competing for 8 years. Her best event is the Pyraminx: a personal-best single of 1.43, set at New Zealand Nationals 2023, puts her in the top 0.34% of the 130,891 people who have ever been ranked in the event, and 14th in New Zealand. Until March 2013, no official Pyraminx solve in the world had been that fast. Across 29 competitions since April 2019, she has put 1,917 official solves on the record across 15 events.

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.
