  • Patent number: 7467795
    Abstract: A modifiable game according to the present invention includes a magnetic base, at least one game token, a plurality of user tokens, and a plurality of overlays. Each overlay may include starting and ending indicia, segmented path spaces, and indicia, such as artwork, representing different themes. Each overlay is preferably uniquely different from any other overlay so as to present unique game experiences. Game tokens may be positioned on the game board or overlay prior to the start of game play and each game token may correspond with another indicia on the board. If a player's user token lands on a path space adjacent the game token, he may advance immediately to a path space adjacent the corresponding indicia. The modifiable game may also include means for advancing user tokens along the path spaces, such as one or more die, a spinner, or even an electronic device.

  • Patent number: 7354040
    Abstract: An educational game and system for nostalgically replicating a baseball game and a method for playing a baseball board game are provided. Two players alternate between the roles of batting and fielding. A series of cards from one deck are turned to advance players around the bases and to accumulate outs. Various decks of cards are used at each player's option to determine the outcome for on-base situations, hitting situations and running situations. Game pieces are used to mark the positions of runners on base and to tally the number of runs scored during a half-inning. An old-fashioned scoreboard is provided to record the total number of runs that are scored at the end of each half-inning. A traditional scorecard is provided to record each play of the game.

    Abstract: A game board where players move their pieces vertically upwards simulates competition in an industry structure, climbing the corporate ladder. Players start with numbered cards and investment wagers, the highest card winning a turn and advancing up the board and winning the others' investments. Players achieve advantages, such as money and the ability to have additional cards in their hand, at predetermined vertical levels along the board. The loser of the turn, the lowest card, must take an action card having incumbent good or bad results. All others advance less than the winner. The game winner has the most money.

Included as elements are a magnetic game board, a multiplicity of miniature figurines, as well as nameholders for each player. Flash cards and answer key elements are used to challenge the young player's growing knowledge of the sport. A beginning child must identify the various parts of the field and place the figurines in the proper playing positions. He or she when shown a flash card having few words thereon, must explain the meaning of the card. A coach or parent with little experience can read an answer key to determine correctness of a response. The principle of the system, essentially no different for baseball or soccer, may be readily structured for other field and court sports. A method of playing a tabletop baseball board game based on this system of training/coaching is also disclosed.

  • Patent number: 5662326
    Abstract: An improvement for a chess set comprising an eight-row by eight-column pattern of sixty four playing squares on a playing surface of a chess game playing board and two sets of visually distinct playing pieces each having eight pawns, two knights, two bishops, two rooks/castles, one queen and one king. A first set of one or more magnets having a North pole and a South pole is arranged in the board underlying the light squares such that the North pole is oriented toward the playing surface. A second set of one or more magnets having a North pole and a South pole is arranged in the board underlying the dark squares such that the South pole is oriented toward the playing surface. A first one of the bishops of each set movable only on the light squares includes a magnet having a North pole and a South pole arranged in conjunction therewith such that the South pole is odented toward the playing surface whereby the first bishops attract to the light squares and are repelled from the dark squares.

  • Patent number: 5588654
    Abstract: A compact game playing apparatus that is easy to carry and use when traveling. The apparatus contains an elongate sheet coupled to two spindles. A plurality of game playing surfaces are printed on the elongate sheet, and rotation of the spindles operate to align a selected one of these game playing surfaces with a window in the apparatus housing. A-magnet attracting metal surface is positioned below the exposed game playing surface so that game pieces, which include magnets, may be placed on the game playing surface without being inadvertently displaced. The housing further contains an integral die throwing apparatus, and an integral drawer for holding game pieces when not in use.

  • Patent number: 5553849
    Abstract: The present invention relates to a combination of game pieces having a ferrous metal member on a peripheral edge or surrounding the periphery thereof, and a magnetic wand for lifting the pieces from a playing board or surface. Because the pieces themselves are not magnetized, they will not adhere to one another when they are either placed on a game board, or in storage. However, the ferrous metal edging on the game tiles allows them to be easily lifted and removed from a playing board or surface.

  • Patent number: 5503400
    Abstract: A chess set construction permitting chess to be played with the chess board in a vertical position, removably mounted in a frame on a wall, and in a horizontal position, as on a table. Each chess piece is bisected, being rejoinable by a tongue and groove. At least one of the halves of each chess-piece has a magnet, and the chess board is a magnetic receptor, such that each such magnet half piece may be held in playing position on the chess board when the chess board is vertical on a wall, with each half piece being viewed in normal upright profile. Display storage provisions are made for the halves of each playing piece not in play. The chess board is removable from the wall frame with the half-pieces remaining in position for continuation of play on a horizontal table.

  • Patent number: 5490675
    Abstract: Game set and storage system in which game pieces are stored in a preset arrangement relative to their starting positions on the game board. The set includes a game piece holder which has a plurality of compartments for holding the game pieces in an inverted position. The board is placed on the holder in an inverted position with its playing surface facing down and the board serving as a cover for the holder. To set up the game the holder is inverted with the now upright board on the under side thereof, and the board is dislodged from the holder, by pressing against the upper surface of the board with a finger inserted through a hole provided in the holder for that purpose. When the holder is lifted away, the game pieces are left in their proper starting positions on the board.

  • Patent number: 5441261
    Abstract: The globe is rotationally molded of iron particles and a plastisol of polyvinyl chloride and has embossed therein, from the mold, lines of longitude and latitude. Two or more layers of magnetized puzzle pieces are formed by printing their indicia on flat, soft, magnetized thermo plastic sheets and then die cut. The indicia is printed such that, when necessary, successive layers of puzzle pieces have their magnets aligned so that specific pieces adhere to specific places on pieces of adjacent layers. When necessary, the pieces are heat formed to conform to the globe shape. Preferably, the first layer contains continental and longitude and latitude information; the second layer, geologic features; and the third layer, political information. The globe stand has a recess therein, the bottom of which is of the same curvature as the globe and may incorporate or have sprayed on iron containing material so that the puzzle pieces may be conveniently stored there when not applied to the globe.
