Pedro Arfux Pereira Cavalcante de Castro has been competing for 10 years. His best event is the 3×3: a personal-best single of 10.06, set at UFMS Space Rubik 2026, puts him in the top 7.6% of the 284,439 people who have ever been ranked in the event, and 377th in Brazil. Until May 2007, no official 3×3 solve in the world had been that fast. Across 3 competitions since July 2016, he has put 75 official solves on the record across four events.

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

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.
