JiYun Kim (김지윤) has been competing for 6 months. Her best event is the Clock: a personal-best single of 6.48, set at Korea Open 2026, puts her in the top 9.0% of the 32,048 people who have ever been ranked in the event, and 61st in Republic of Korea. Until June 2010, no official Clock solve in the world had been that fast. Across 2 competitions since March 2026, she has put 25 official solves on the record across five events. JiYun 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.
