PROBLEM TO BE SOLVED: To enable an Othello game from two persons till the maximum of 6 persons to be played on the same board surface and even by one person on two or three surfaces in the Othello game by providing a hexahedron piece having 6 colored faces instead of a cylindrical piece having 2 colored faces. ;SOLUTION: First, a piece is shaped into a regular hexahedron (a die shape) to prepare colored 6 faces differ from each other. Thus, a piece for the maximum 6 persons can be prepared. A player distinguishes his own piece from other ones by recognizing the upper face parallel to the bottom face as his own color while the piece is placed. The player plays the game by sandwiching and turning upside down opponent's piece between his own longitudinal, lateral and oblique pieces to make his own piece (color). When the player does not have his own piece and cannot sandwich the opponent's piece, he will place only one piece in a division of the board (limited in one direction of the board divisions) along the faces other than the upper face and bottom face under the state of his or opponent's placed piece to wait for the next turn.;COPYRIGHT: (C)1997,JPO
