Your task in this addictive and fun physics-based game is to annihilate all of the positive and negative particle balls on each level. Place the particle balls above the line and press play to let physics do it's work. Balls of opposite polarity annihilate each other. To clear the level there should be no particle balls remaining. Sensors can control various objects and are triggered when a ball rolls over them. An auto-save feature automatically saves your progress so you can suspend the game and continue playing where you left off at a later time. Use YOUR MOUSE to control the game. Have fun!
