Mahbubul Hossain Robin
3×3 one-handed · top 4.5% of 73,695 all-time · competing since December 2017 · 2017ROBI09
Mahbubul Hossain Robin has been competing for 9 years. His best event is the 3×3 one-handed: a personal-best single of 13.07, set at Cube Carnival Bangladesh 2023, puts him in the top 4.5% of the 73,695 people who have ever been ranked in the event, and 15th in Bangladesh. Until January 2010, no official 3×3 one-handed solve in the world had been that fast. Across 8 competitions since December 2017, he has put 170 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one; 56% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 11.35 in December 2017 to 9.38, a 17% improvement. Mahbubul 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.
