Isaac Lu

3×3 · top 8.2% of 284,439 all-time · competing since December 2023 · 2023LUIS05

Isaac Lu has been competing for 3 years. His best event is the 3×3: a personal-best single of 10.25, set at Puzzling Parramatta 2024, puts him in the top 8.2% of the 284,439 people who have ever been ranked in the event, and 744th in Australia. Until May 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since December 2023, he has put 90 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 17.20 in December 2023 to 10.25, a 40% improvement. Isaac has entered four competitions, more competitions than 78% of everyone who has ever competed.

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.
