Alexander Enrique Mercado Blanco has been competing for 10 months. His best event is the Pyraminx: a personal-best single of 3.18, set at Kids Cubing IALA 2026, puts him in the top 4.3% of the 130,891 people who have ever been ranked in the event, and 24th in Bolivia. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 4 competitions since December 2025, he has put 120 official solves on the record across six events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 8 counted rounds. His Pyraminx best has come down from 5.03 in December 2025 to 3.18, a 37% improvement. Alexander has entered four competitions, more competitions than 78% 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.
