Super Blue and Gray (2003)

This game fuses the game Blue and Gray with checkers. In it, players attempt to navigate their Captain piece to the middle, moving along a winding road on the board to be the first to get their Captain to the middle of the board. In addition, players can promote their Private pieces to Sergeants, which adds backwards mobility to a Private.
