  • Patent number: 4319754
    Abstract: The specification of the present invention discloses a game board apparatus which allows two parties to efficiently play numerous games in which both parties move simultaneously and the observation of the opponent's playing surface is limited. The apparatus includes two parallel upright members with a removable shield disposed between these members. Blocking means are also provided for each upright member to selectively limit the observable area of the opposite upright portion when the shield is removed. According to an aspect of the invention, specialized playing pieces are provided which co-operate with said blocking and are engagable with the upright members such that a portion of the playing piece is visible when the blocking means is closed, thus simplifying the recordal of game data.

  • Patent number: 4232864
    Abstract: The specification discloses a game apparatus having at least two identical playing surfaces and playing pieces adapted to releasably engage the playing surfaces. The apparatus also includes means to superimpose the playing surfaces wherein at least one of said playing surfaces is movable from the superimposed position. The playing surfaces and playing pieces are at least partially transparent providing observation of nonoverlapping playing pieces and at least recognition of overlapping playing pieces when the playing surfaces are superimposed. The game structure allows for simultaneous movement of the playing pieces by all players and increases the possibility of confrontation with a number of players. The game apparatus is designed to allow realistic observation from above superimposed playing surfaces, or in some instances, side viewing along the plane of these surfaces. The game apparatus allows for infinite variation of the board surface.
