Puzzle Cannon is a physics puzzler in which your goal is to clear colored blocks from each stage. Aim your cannon and shoot balls that will stick to blocks of the same color. When a ball is touching a group of two or more blocks of the same color, all of the balls and blocks in the group will explode. You can create larger groups by moving blocks with balls of another color, which won't cause the blocks to explode. You have an unlimited number of balls, but your time is limited!
