Saku Rosenborg has been competing for 4 years. His best event is the 2×2: a personal-best single of 2.55, set at Deutsche Cube Days Helsinki 2024, puts him in the top 9.4% of the 186,767 people who have ever been ranked in the event, and 124th in Finland. Until February 2008, no official 2×2 solve in the world had been that fast. Across 10 competitions since March 2023, he has put 203 official solves on the record across six events.

His 2×2 best has come down from 7.03 in May 2023 to 2.55, a 64% improvement. Saku 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.
