Nguyễn Tuấn Kiên
3×3 · top 2.1% of 288,433 all-time · competing since July 2023 · 2023KIEN04
Nguyễn Tuấn Kiên has been competing for 3 years. His best event is the 3×3: a personal-best single of 7.54, set at Hanoi Summer 2025, puts him in the top 2.1% of the 288,433 people who have ever been ranked in the event, and 109th in Vietnam. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since July 2023, he has put 109 official solves on the record across four events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 88% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 10.14 in July 2023 to 7.54, a 26% improvement. He has entered eight competitions, more competitions than 90% of everyone who has ever competed.

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.
