Arumin Sivakumar
3×3 · top 4.0% of 288,433 all-time · competing since May 2025 · 2025SIVA07
Arumin Sivakumar has been competing for a year. His best event is the 3×3: a personal-best single of 8.59, set at West Coast Cubing Western Championship 2026, puts him in the top 4.0% of the 288,433 people who have ever been ranked in the event, and 2,265th in the United States. Until July 2008, no official 3×3 solve in the world had been that fast. Across 10 competitions since May 2025, he has put 181 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 90% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 56.74 in May 2025 to 8.59, an 85% improvement. Arumin has entered ten competitions, more competitions than 92% 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.
