Zachariah Black has been competing for 7 years. His best event is the 2×2: a personal-best single of 1.66, set at West Chester Fall 2022, puts him in the top 2.9% of the 186,767 people who have ever been ranked in the event, and 1,121st in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since January 2020, he has put 129 official solves on the record across ten events.

Zachariah has entered three competitions, more competitions than 69% of everyone who has ever competed.

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.
