  • Patent number: 4653759
    Abstract: The disclosure is of a three-person chess game and board having a central playing area in the form of an equilateral triangle bordered at each of its three sides by a rectangular playing field or area having at least two rows of eight squares each according to at least part of the conventional chess or checker board. Each rectangular field is contiguous with its side of the triangle and moves are made from the rectangle into the triangle and subsequently into either of the other rectangles according to prescribed rules. At least some of the moves are dictated by an element of chance, such as the roll of one die. The rectangles are identical and three conventional chess sets are used, albeit these may be of contrasting colors as may be the markings of the chess board squares as well as the smaller triangles into which the basic central triangle is subdivided.
