A 3-D abstract strategy game that has players sliding blocks into the game cube in an attempt to create a path to the opposite side of the cube. Your tunnel doesn't have to be straight. It can twist or turn. You need to balance both offense and defense to make sure your opponent doesn't complete their tunnel before you.
