Jack O'Mahony has been competing for 15 years. His best event is the 3×3: a personal-best single of 7.75, set at Canberra Autumn 2022, puts him in the top 2.4% of the 284,439 people who have ever been ranked in the event, and 236th in Australia. Until July 2008, no official 3×3 solve in the world had been that fast. Across 28 competitions since May 2011, he has put 1,214 official solves on the record across 14 events.

His 3×3 best has come down from 35.31 in June 2011 to 7.75, a 78% improvement. Jack has entered 28 competitions, more competitions than 98% 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.
