Jawa Timur Open 2026

The lively halls of Pasar Atom Mall hummed with intense focus and the steady clack of plastic as eighty solvers gathered in Surabaya, East Java, Indonesia. Running from June 20 to June 21, the tournament floor became a showcase of relentless technical growth. Solvers across ten distinct disciplines took their places on the staging mats, each looking to chip seconds away from their personal records under the tournament lights. Over two full days of action across fourteen competitive rounds, the atmosphere in the retail complex reflected a community pushing its boundaries at every station.

While the top steps of the podiums saw fierce battles, the true heartbeat of the gathering lay in the dramatic drops in personal records. Across the field, competitors shaved massive percentages off their career marks, proving that long practice hours away from the spotlight yielded immediate dividends. From opening rounds to final showdowns, the cubing competition delivered sharp progress across both traditional twisty puzzles and complex side events.
