Sam Calderbank

2×2 · top 8.0% of 186,767 all-time · competing since July 2023 · 2023CALD12

Sam Calderbank has been competing for 3 years. His best event is the 2×2: a personal-best single of 2.41, set at Rubik's UK Championship 2024, puts him in the top 8.0% of the 186,767 people who have ever been ranked in the event, and 545th in the United Kingdom. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since July 2023, he has put 134 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 98% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 17.47 in July 2023 to 13.47, a 23% improvement. Sam has entered five competitions, more competitions than 83% of everyone who has ever competed.

The story so far

Competitions

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.
