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! VERY ADDICTING. Great 'plasma' animations and incredible soundtrack. Great for one-player or two SIMULTANEOUS players! Setup options allows you to choose from a jukebox of incredible music and select different artwork for the nuclear particles.
