A game of chess uses a board that consists of four concentric rings of playing areas, the center ring being circular. The center ring has four playing areas, the second ring twelve, the third ring twenty and the fourth ring twenty-eight. The abutting playing areas are of contrasting appearance as is usually the case in a chess board. Four rows of corner playing areas, which may all be trilateral, radiate symmetrically from the center of the board. The outermost corner areas may be other shapes, such as circular or rhombic. The remainder of the playing areas are quadrilateral. In playing the game, the rook and queen pieces are allowed to travel around the board, moving from rank to file to create a logically valid flanking action and a centrifugal emphasis that is entirely absent in the conventional game.
