Klax is an action/puzzle game where your objective is to catch various colour falling tiles and create rows, columns, or diagonals of a single colour. Each level demands a specific pattern, and the tiles fall faster, more at a time, and in an increasing number of colours as the game progresses.
The gameplay revolves around using your wits to clear the screen by matching colours, with each level introducing new challenges. The clock is ticking, and you must think quickly to avoid missing any opportunities to score points.
