Krzysztof Żerucha has been competing for 18 years. His best event is the 3×3 one-handed: a personal-best single of 12.50, set at Polish Open 2018, puts him in the top 3.7% of the 73,695 people who have ever been ranked in the event, and 104th in Poland. Until January 2010, no official 3×3 one-handed solve in the world had been that fast. Across 40 competitions since June 2008, he has put 1,837 official solves on the record across 14 events.

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.
