Rotate and move the falling nuclear particles to align three or more in any direction: horizontally, vertically, or diagonally. When three or more pieces line up, they will 'explode' and disappear. As pieces fall and create explosions of their own, a 'chain reaction' occurs and bonus points are awarded. When each new level is reached, the particles will fall a faster and faster! What is the largest chain reaction that you can create? Features Infinite Levels Addictive Gameplay! Smooth animation runs on modest hardware Source: The Developer Website.
