Robots control the galaxy and the fate of the universe lies in question. Armed with an experimental spaceship, players must put their math skills to the ultimate test as they blast through space to defend the human race and defeat the robotic rulers. Players master math skills in a variety of brain-busting categories including addition, subtraction and multiplication. Whether competing with a friend in Four Player Battle Mode, or testing their computation abilities in Challenge or Adventure modes, players multiply, add and subtract their way through three difficulty levels.
