This chess-like game was designed during the development of the Macintosh computer, and released around the same time as the computer itself. Thus it is one for the first games made for the Mac, and perhaps the only one published by Apple. It comes in a beautiful false book type packaging. Because Apple wanted to target their new computer towards business users and not give the impression it was just another 'games machine', they did not market the game well and not many copies were sold, making it very rare.
