Play Klax (Japan) on gb Online

Klax on the Game Boy came out in 1990, a portable version of the arcade puzzle game by Atari Games. It was one of those straightforward, no frills titles that fit right in with the early handheld library, offering a clean and focused alternative to the action and adventure games crowding the system.

You control a paddle at the bottom of the screen, catching colored tiles that roll down a conveyor belt. Your goal is to arrange these tiles in rows, columns, or diagonals of three or more matching colors to clear them. The core mechanics involve careful stacking and constant decision making, since you can also drop tiles into a holding bin for later use. The pace starts deceptively calm but escalates quickly, demanding faster reactions and smarter planning with each level. It feels like a tense, satisfying battle against the inevitable flow of tiles.
