AmzPlayer

AmzPlayer is A Modern Player for Zillions of Games.  It comes with over 100 games, and you can download thousands more, or create your own.

Mostly the games it can play are for two players, human against computer, with everything out in the open (no hidden cards). That includes a wide variety of games from simple tic-tac-toe (or noughts and crosses) through to Chess, Go and anywhere in between. It includes many games of historical interest, and games not widely known that are still very playable. Single player games (puzzles) are possible too.

The software includes a powerful artificial intelligence in the form of a computer opponent that can be a real challenge to beat.
