On Guard is a simple dexterity game made by Parker Brothers in 1967. It can be played by two players, or 4 with players working in teams with the goal of being the first player or team to score 5 points. The game table is a fairly heavy plastic construct, with large springs mounted beneath each of the rectangular board's 4 corners. Players depress the springs, moving a steel ball through the obstacles towards a goal. The real point of interest is that the two scoring areas feature both goals, side-by-side. So attempting to score can be very dangerous indeed! Game components: Plastic game table, metal ball, instructions.
