Today's Free App of the Day is Trionix
This is a well reviewed (by at least a couple long time Amazon reviewers) game. It's kind of like Reversi/Othello according to reviewers. It reminds me of Chinese checkers. :D Beautifully done, simple gameplay. Can be played against a computer or up to three other players.
5 of 5 reviews are four stars and above.
