Arun Bilguun
3×3 · top 2.8% of 288,433 all-time · competing since October 2024 · 2024BILG01
Arun Bilguun has been competing for 2 years. His best event is the 3×3: a personal-best single of 7.99, set at MR Ulaanbaatar 2025, puts him in the top 2.8% of the 288,433 people who have ever been ranked in the event, and 43rd in Mongolia. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since October 2024, he has put 147 official solves on the record across four events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 84% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 12.16 in October 2024 to 7.99, a 34% improvement. Arun has entered eight competitions, more competitions than 90% 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.
