DualGrid
Read full descriptionHide full description
DualGrid is a puzzle game where you solve the same board using two different sets of rules. In COLOR MODE, clear groups of two or more adjacent tiles of the same color. Tiles fall after each move, and new tiles refill the board. In PIPE MODE, follow connected pipes and guide the character from the start to the goal. Switch between the two modes to reshape the board and open a path forward. As you progress, new mechanics appear, including rotating tiles, wild colors, one-way valves, frozen tiles, garbage tiles, and checkpoints. With intuitive touch controls, DualGrid is easy to enjoy in a quick session or as a deeper puzzle challenge.
