7×7 · top 0.15% of 14,226 all-time · competing since August 2018 · 2018TUNG05

Trương Khánh Tùng has been competing for 8 years. His best event is the 7×7: a personal-best single of 1:46.42, set at Hanoi Summer 2025, puts him in the top 0.15% of the 14,226 people who have ever been ranked in the event, and 2nd in Vietnam. Until July 2019, no official 7×7 solve in the world had been that fast. Across 22 competitions since August 2018, he has put 699 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 55% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 10.17 in August 2018 to 6.37, a 37% improvement. He has entered 22 competitions, more competitions than 97% 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.
