2×2 · top 1.6% of 186,767 all-time · competing since July 2023 · 2023QUAN13
Lưu Đức Quang has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.36, set at Hanoi Summer 2025, puts him in the top 1.6% of the 186,767 people who have ever been ranked in the event, and 25th in Vietnam. Until November 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since July 2023, he has put 99 official solves on the record across three events. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 5 counted rounds. His 2×2 best has come down from 4.35 in July 2023 to 1.36, a 69% improvement. He has entered five competitions, more competitions than 83% 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.
