Abstract: A board game includes a board divided into a multiplicity of contiguous, equally-sized, equilateral triangles, half of them colored as to be visually distinguishable from the other half, and arranged in an alternated sequence of colors, and a plurality of playing members associated therewith, the ratio of playing members to triangles being 12 to 54, there being two visually distinguishable sets of such members. Each playing member is of four-sided configuration, each side defining a triangle congruent with each board triangle. The movement of each member takes place by rotating that piece about a board triangle leg until the piece is seated on a board triangle contiguous with the first-mentioned board triangle.
