  • Patent number: 4813679
    Abstract: A strategy oriented board game wherein the board is divided into a plurality of elongated slidable strips. A first set of strips have intersections formed by first parallel lines intersecting second parallel lines. A second set of strips have similar intersections relatively offset from the intersections of the first set of strips. When the edges of the strips are aligned, the parallel lines are all connected forming linear intersecting pathways running diagonally across the face of the strips. Each player has a plurality of markers which are placed at home positions at opposite ends of the board. The markers are selectively movable across the strips along the pathways formed by the connection of the parallel lines. The objective is to move a player's marker to the opponent's home positions. According to the rules the strips may be slid, thereby re-positioning the markers located on the slid strip.
