Abstract: A chess set game (2) includes a chess set (4), in which two sets of chess pieces (44) are housed within a container (8), and a chess board (6). The board can be divided into four separable quadrants (10-13) which are secured to one another. The chess pieces and the squares (38, 40) of the board have magnets (46, 42) so the chess pieces are attracted to and securely fastened to the centers of the squares. The chess board includes rank and file ID devices (50, 48) which permit the user to change file and rank indicia (54-60) according to which player has the white pieces. The container includes a rectangular bottom (70) and four sides (74-77) pivotally mounted to the outer edge (72) of the bottom. The four sides and the bottom have magnetized spaces (108, 118) against which the chess pieces are secured. Each of the sides has a top portion (82-85) extending therefrom so that when the sides are in their upright, closed positions, the top portions create a closed top (80) for the container.

Abstract: A timing device is provided for the differential timing of game play, such as chess, employing an easily readable display means and an accurate timing means. According to the preferred embodiment of the present invention, the display means further comprises two concentric articulating discs of different color, usually black and white. The display is connected to an electric motor driven by an accompanying electric circuit such that one disc is driven by the motor. The direction of travel of the motor is controlled by player actuated switches which are tripped upon completion of each move. Differential time is displayed by the eclipse of one disc by the other.
