Jong-Beom Lim (임종범) has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.94, set at Round Rock Mega Cube Day 2026, puts him in the top 4.4% of the 189,179 people who have ever been ranked in the event, and 120th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since September 2023, he has put 89 official solves on the record across five events.

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.
