Efe Hasan Şentürk has been competing for a year. His best event is the Skewb: a personal-best single of 3.17, set at November Weekend İstanbul 2025, puts him in the top 5.9% of the 73,281 people who have ever been ranked in the event, and 24th in Turkey. Until February 2014, no official Skewb solve in the world had been that fast. Across 7 competitions since December 2024, he has put 266 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one; 78% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 10.38 in December 2024 to 2.49, a 76% improvement. Efe has entered seven competitions, more competitions than 88% 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.
