Yu Da-Hyun (유다현) has been competing for 18 years.

Until June 2017, no official Megaminx solve in the world had been that fast. Across 32 competitions since August 2008, she has put 813 official solves on the record across 17 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.
