Illia Kozlov (Ілля Козлов) has been competing for 7 years. His best event is the Skewb: a personal-best single of 2.89, set at Cubes Masters Zhytomyr 2021, puts him in the top 4.5% of the 73,281 people who have ever been ranked in the event, and 34th in Ukraine. Until February 2014, no official Skewb solve in the world had been that fast. Across 12 competitions since June 2019, he has put 357 official solves on the record across nine events.

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.
