YunKyu Cho (조윤규) has been competing for 2 years. His best event is the 3×3: a personal-best single of 8.64, set at Anyang Haseyo 2025, puts him in the top 4.0% of the 284,439 people who have ever been ranked in the event, and 239th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 2 competitions since September 2024, he has put 30 official solves on the record across four events. His 3×3 best has come down from 12.88 in September 2024 to 8.64, a 33% improvement. YunKyu has entered two 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.
