Play Boulder Dash EX (J)(Polla) Online

Boulder Dash EX came out for the Game Boy Advance in 2002, developed by a company called Polla. It was part of that early GBA wave where classic arcade and puzzle concepts got polished up for handheld play, sitting alongside other thoughtful, screen based puzzlers that didn't rely on big stories or flashy graphics to hold your attention.

You control a little explorer named Rockford, digging through dirt to collect a set number of gems on each screen before the timer runs out. The core mechanics are simple but punishing; you carve paths through soft earth, avoid being crushed by unstable boulders you dislodge, and outsmart enemies that follow set patterns. The pacing is deliberate, almost tense, as a single misplaced dig can collapse a section or block your only exit. It feels like a careful, constant calculation of risk and reward with every move you make.
