Pyraminx · top 6.0% of 129,321 all-time · competing since September 2024 · 2024SOTI01

Kristo Sotirov has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 3.64, set at Sofia Open 2026, puts him in the top 6.0% of the 129,321 people who have ever been ranked in the event, and 17th in Bulgaria. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since September 2024, he has put 439 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 14% around a typical one; 65% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 5 DNFs. His Pyraminx best has come down from 7.17 in September 2024 to 3.64, a 49% improvement. Kristo has entered ten competitions, more competitions than 92% of everyone who has ever competed.

Best single per competition, Pyraminx. Faster is higher — the axis is the right way up.

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.
