Cooper Korthuis has been competing for 2 years. His best event is the 3×3: a personal-best single of 10.18, set at Vanderbilt Winter 2025, puts him in the top 8.0% of the 284,439 people who have ever been ranked in the event, and 4,401st in the United States. Until May 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since March 2024, he has put 84 official solves on the record across eight events.

Cooper has entered four competitions, more competitions than 78% 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.
