Abstract: The game comprises a board 2, having a playing area marked out with adjoining similar equilateral triangles 6. The playing pieces are regular tetrahedrons 12 having faces sized to fit in the triangles, the four faces each carrying a different designation e.g. different colour indicative of different score levels. Each piece can move by flipping (i.e. moving from one triangle to a triangle with a common side by pivoting about the axis of the common side) and in one option by twisting (i.e. by rotating in the same triangle through an angle of 120 DEG  about an axis normal to the triangle and pssing through the apex of the piece). One piece attacks another piece by moving into an adjoining triangle and presenting a surface of higher score level to the facing surface of the defending piece. If the defending piece cannot escape from a situation where the surface of an attacking piece is of higher level, the piece is lost. As shown, the playing area is a hexagonal and divided into twenty-four triangles 6 with two sets of base triangles 8, 10 from which movement of playing pieces commences. <IMAGE>
