Mark Bai has been competing for 4 years.

Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since January 2023, he has put 55 official solves on the record across five 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.
