There are a lot of playing classic board games as Gomoku/Renju/Othello. But this product has some unique features: the X & O allows you:
  1. play 26 different games:

    Five in a rows game

    Four in a rows games

    Othelo games

    Checkers games

    Chess games

    Go games

    Other

    The games marked with '*' are in developing phase and X & O plays these games as a very weak player

  2. play games with funny variations as: five in a rows games with atomic bomb, neutral stones and common center
  3. play renju with rules of Renju International Federation
  4. turn on and off the tournament rule for gomoku, pente and keryo-pente
  5. use a database of games
  6. play games using different notations
  7. use product on any platform (Windows, Unix) that has Java Virtual Machine and play online
  8. and more, more, more ...
And last but not least: the X & O plays very, very good !
