ABSTRACT:
Six-sided cubic blocks with interfitting and repelling sides have selected representations on each side according to predetermined patterns of relationships between side structures and representations. The blocks are assembled in horizontal and vertical arrays to achieve numerical goals of representations on faces of the arrays. Two persons work on the vertical array from opposite sides seeking to attain their own goals, while preventing opposite persons from attaining their goals.
