    Abstract: The present invention provides a game kit comprising a board and a plurality of pieces. The playing field of the board comprises a plurality of intersecting points created by three sets of parallel line segments meeting at an angle of 60.degree.. The points are especially marked to designate the locations on which the pieces are to be placed, with the object of forming equilateral triangles. Interspersed between each of the three sets of parallel line segments is an auxiliary set of parallel line segments. The auxiliary line segments create a second set of intersecting points on the board which may be used as an aid in identifying the location of potential triangles. The game pieces may be played selectively with their face or back directed upwards to designate the players and are provided with markings to identify said face and back. The equilateral triangles are formed by players strategically placing their pieces, in turn one piece at a time, on the unoccupied specially marked intersecting points.
