Sadnan Sakib Annan
3×3 · top 2.8% of 284,439 all-time · competing since December 2019 · 2019ANNA03
Sadnan Sakib Annan has been competing for 7 years. His best event is the 3×3: a personal-best single of 8.00, set at Rajshahi Cube Open 2026, puts him in the top 2.8% of the 284,439 people who have ever been ranked in the event, and 34th in Bangladesh. Until July 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since December 2019, he has put 226 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 14% around a typical one; 62% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 2.84 in December 2019 to 1.88, a 34% improvement. Sadnan has entered five competitions, more competitions than 83% 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.
