Square-1 · top 1.1% of 25,272 all-time · competing since May 2022 · 2022KIER01

Joanna Kierznikiewicz has been competing for 4 years. Her best event is the Square-1: a personal-best single of 6.44, set at Rubik's WCA European Championship 2026, puts her in the top 1.1% of the 25,272 people who have ever been ranked in the event, and 20th in Poland. Until May 2017, no official Square-1 solve in the world had been that fast. Across 64 competitions since May 2022, she has put 2,800 official solves on the record across 14 events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 70% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 20.01 in May 2022 to 7.36, a 63% improvement. Joanna has entered 64 competitions, more competitions than 99% 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.
