Karl Edward Rikk has been competing for a year. His best event is the 3×3: a personal-best single of 10.46, set at PärNuti Cubing 2025, puts him in the top 8.8% of the 284,439 people who have ever been ranked in the event, and 29th in Estonia. Until February 2007, no official 3×3 solve in the world had been that fast. Across 7 competitions since October 2024, he has put 246 official solves on the record across eight events.

His 3×3 best has come down from 19.16 in October 2024 to 10.46, a 45% improvement. Karl has entered seven competitions, more competitions than 88% 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.
