a golf game is played by two players putting golf balls into nine pairs of ball receiving receptacles . each pair of receptacles is marked with two different color codes . as a result of a putted golf ball entering a color coded ball receiving receptacle , an electric solenoid turns a valve either to the right or left , which directions correspond to the two different color codes . the valves control the flow of counters along intersecting channels which terminate in a receiving area for accumulating the counters to provide a score for each player .
