  • Patent number: 4004810
    Abstract: A game including a board with a polygonal playing area divided into a plurality of wedge-shaped segments, each for use by a different player. A pathway is included in each segment, each pathway being divided into a plurality of playing spaces over which a playing piece is moved. Each pathway has a finishing position which is common with the other pathways, and also a starting position. At various points along each pathway, the pathway branches into first and second paths which thereafter rejoin. The first path of each branching portion of a pathway contains a greater number of playing spaces than does the second path of the branching portion. Also included are a plurality of gate elements, each disposed adjacent a different one of the second paths for movement between a first position in which the gate element "blocks" the passage of a playing piece, and a second position in which the gate element does not block the passage of a playing piece.
