There are 2 little Quarks battling against each other by trying to control as much subnuclear matter as possible. Click on the blocks on the board to gain control of it and place a bit of subnuclear matter. Once the particle gets too big it becomes unstable - the next click on it starts a nuclear reaction. The one who caused this explosion gains control of the surrounding fields. Particles in corner fields become unstable when they reach a size of 3. Particles at the border become unstable at the size of 5. All other particles become unstable at the size of 8. First one to reach the designated number of points wins. For 1 or 2 players.
