Your objective in Color Joy is to close all of the portals by guiding shapes of the same color to them. Move the shapes to the portals by removing blue transparent objects from the stage. Dark brown objects are fixed and light brown objects will move according to the laws of physics. When same-colored shapes touch each other, they will combine into one shape. There are three stars in every level. You don't need to collect stars to complete a level, but collecting enough of them will unlock bonus stages.
