Đặng Khoa Nguyên
3×3 · top 5.1% of 284,439 all-time · competing since January 2024 · 2024NGUY07
Đặng Khoa Nguyên has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.10, set at Cube Against Cancer Hanoi 2026, puts him in the top 5.1% of the 284,439 people who have ever been ranked in the event, and 318th in Vietnam. Until May 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since January 2024, he has put 76 official solves on the record across six events. Solve to solve, his 3×3 times vary about 20% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 2×2 best has come down from 3.86 in July 2024 to 2.85, a 26% improvement. He has entered four competitions, more competitions than 78% 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.
