Zone X (1975)

"Two Players - Zone Maker & Zone Breaker In Zone X, the players alternate in fixing a hidden target point ("Zone X") on the Marker Grid. The opponent (Zone Breaker) attempts to zero in on the target using their search board. The Target Point is picked by the Zone Maker who then draws two intersecting lines on the Marker grid. This creates 4 Zones that are colour-coded (Blue, Green, Red, Yellow). The Zone Breaker calls Zone keys using their search board. The Zone Maker responds by stating the Zone colour in which the key called lies. The Zone Breaker places a corresponding colour peg into their search board and, using logic and luck, zeroes in on the target using as few pegs as possible. Zone X can be played at 3 levels of challenge: 1.Straight line zoning 2.Curved line zoning 3.Random shape line zoning - from back of box This game is in the same style of game box as Mastermind, i.e. two interesting and unusual people on the box.
