Samuel Giraldo Alcalá has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.83, set at Avenida Chile XXXV 2026, puts him in the top 7.0% of the 284,439 people who have ever been ranked in the event, and 266th in Colombia. Until October 2007, no official 3×3 solve in the world had been that fast. Across 10 competitions since May 2023, he has put 124 official solves on the record across four events.

His 3×3 best has come down from 29.05 in May 2023 to 9.83, a 66% improvement. Samuel has entered ten competitions, more competitions than 92% 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.
