Space Shooter Free is a color-match puzzler. Launch spheres, pairing them in groups of 3 to clear the screen TO SAVE AND DEFEND PLANET EARTH. To launch the sphere, touch the screen where you want the sphere to go. As you clear screens the levels become harder. You are also in a fight against time, because the game collapses. If the launcher sphere touches other game spheres, the level is over. This game-type is also known as bubble shooter, bubble pop, bubble bust, bubble buster, and/or marble type game.
