A growing collection of computer games that are freeware, open source or free to play.

Explorer is a veteran on the Computer Go scene: Anders Kierulf started implementing tactics for the Smart Go Board in 1984. In 1987/88 Ken Chen and Kierulf created the first version of Explorer. Since 1989, I have been the main developer.
Explorer’s best result was to win the first Computer Games Olympiad in London 89, ahead of nine other programs including Goliath and Go Intellect. It came second in the 1995 and 1996 North American Championships, and sixth in the 1995 International Computer Go Congress.
Explorer 3.3 should run on any Macintosh, including 68k and PPC. The program uses Anders Kierulf’s Smart Game Board, and is written in the Modula-2 language.

Note: As of November 2000 the game is freeware. The contact info and shareware information in the readme file is obsolete. Please ignore.
