Moran Grinstein

3×3 · top 2.1% of 284,439 all-time · competing since October 2022 · 2022GRIN02

Moran Grinstein has been competing for 4 years. His best event is the 3×3: a personal-best single of 7.59, set at Folsom Winter 2023, puts him in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 1,257th in the United States. Until July 2008, no official 3×3 solve in the world had been that fast. Across 24 competitions since October 2022, he has put 688 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 66% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 12 DNFs. His 3×3 best has come down from 24.94 in October 2022 to 7.59, a 70% improvement. Moran has entered 24 competitions, more competitions than 97% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
