Turrets of different colors move continuously along a ring conveyor to disassemble the complex design in the Pixel Carousel. Fire cannons from the live queue with keys one through four, or simply tap to have the cannons shoot exposed outer pixels of their hue while quickly moving along the edge of the picture. Carefully line up your volleys, wisely save the number of available moves for the sake of maximum stars for a perfect result, and completely erase all the extra cubes from the canvas in the Pixel Carousel.
