This is essentially a nice package for Borland's sample Gomoku game, known on the PC as Turbo Gomoku. A second, advanced AI was planned but never finished.
An amusing detail is that the avatar for the human player is a simple but recognizable graphic of J. R. "Bob" Dobbs, the figurehead of the Church of the SubGenius. Four special characters in the ST allow this icon to be assembled, though I don't think it has been used very much. This is the first time I have seen it in a game.
