Matias Gonzalo Rivero Zambrana has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.56, set at Pre Nacionales La Paz 2025, puts him in the top 2.4% of the 186,767 people who have ever been ranked in the event, and 22nd in Bolivia. Until November 2008, no official 2×2 solve in the world had been that fast. Across 12 competitions since January 2024, he has put 201 official solves on the record across five events.

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.
