Henry Helmuth has been competing for 13 years. His best event is the 3×3 one-handed: a personal-best single of 8.49, set at Berkeley Fall 2025, puts him in the top 0.31% of the 73,695 people who have ever been ranked in the event, and 49th in the United States. Until May 2015, no official 3×3 one-handed solve in the world had been that fast. Across 69 competitions since November 2013, he has put 2,616 official solves on the record across 14 events.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
