The Black Path Game (also known by various other names, such as Brick) is a two-player board game described and analysed in ''Winning Ways for your Mathematical Plays''. It was invented by Larry Black in 1960.〔.〕 It has also been reported that a game known as "Black" or "Black's Game" was invented in 1960 William L. Black. This "William L, Black" (possibly known as "Larry") was at that time an undergraduate at the Massachusetts Institute of Technology, investigating Hex and Bridg-it, two games based on the challenge to create a connected “chain” of counters that link opposite sides of a game board. The creative outcome of Black’s research was a new topological game that his friends (perhaps unimaginatively) called Black (Gardner, M. 1984. Martin Gardner’s ''Sixth Book of Mathematical Diversions from "Scientific American”.'' University of Chicago Press, Chicago., Gardner, M. 2005. ''Martin Gardner’s Mathematical Games: The Entire Collection of His Scientific American Columns''. Mathematical Association of America: CD-ROM: Pennycook, A. 1985. ''The Puffin Book of Indoor Games''. Penguin, Harmondsworth: originally published as ''The Indoor Games Book'', Faber, London, 1973). ==Rules== The Black Path Game is played on a board ruled into squares. Any square that is not empty is filled with one of the following configurations: Image:Truchet-tile-1.svg Image:Truchet-tile-2.svg Image:Truchet-tile-3.svg These tiles are the three ways to join the sides of the square in pairs. The first two are the tiles of the Truchet tiling. One edge on the boundary of the board is designated to be the start of the path. The players alternate filling the square just after the end of the current path with one of the three configrations above, extending the path. The path may return to a previously filled square and follow the yet-unused segment on that square. The player who first causes the path to run back into the edge of the board loses the game.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Black Path Game」の詳細全文を読む スポンサード リンク
