I discovered this game while making purchases from Rose & Pentagram Designs. According to them, this game did exist in the 1500s. It is a capture game, similar to checkers, but is played on a circular board. The attacking side has 7 tokens that circle the board's outer ring. The object is for them to capture the center spot by placing 2 tokens there. The defender has only 4 token and can only win by capturing all but 1 attacker or rendering the attacker's tokens immobile. The board is 5 concentric circles around a center spot. It is sliced int0 8 wedges. One of those wedges is considered a neutral zone where no captures can take place. Capturing is by jumping. Though the defender may never enter the center square, a jump can be made capturing a piece in the center square. (Oops, this is a circle, not Hollywood Squares.) Remember, it takes 2 attacker pieces in the center spot to win.
Movement is along straight lines (forward, backward, side-to-side) at 1 square per turn. There are no diagonal moves. Here's the kicker. The attackers may NEVER MOVE BACKWARD! They can only move side-to-side and forward toward the center spot, even for jumping.
I will work on getting some graphics here so you can visualize the unique game.
