Games comprising playing boards and pieces

摘要

In a game played by moving pieces to significant positions on a checkerboard (1) each square (2) is formed with a polygonal recess or corollaries (3) into which fits a polygonal projection or corollaries (6) beneath each piece so that the piece is fixed in a selected position about a vertical axis normal to the board. A number of arrangements or projections on the pieces and recesses in the squares and vice versa enable games to be played which depend on the orientation of the pieces as well as on their locations.
