  • Publication number: 20130300064
    Abstract: A stacking game utilizes a rock shaped bowl base with an internal, asymmetrical cavity. A plurality of variously shaped and sized asymmetrical game members, optimally configured as misshapened stones, are placed, in turn by each player, within the cavity. The cavity is eventually filled with the game members and then additional game members are placed on each other to form a “rock pile.” Players whose placement of a game member causes one or more of the game members to fall off the pile are eliminated. The only player who does not cause a game member to fall is the winner.
