Has plenty of game variations (you can toggle ones wild, spot-on, etc) - so whatever variation you want is probably available here along with a decent AI to play against. The interface is simple and utilitarian which is a big positive in my book. If you came for flashy animation look elsewhere but if you just want to play a fun, easy to learn strategy game (though luck helps too), buy it. Only four stars because while the AI is decent, it could be better at least in some of the game variations. For example I recently played 50 games (ones wild = OFF, spot-on = ON, just one computer opponent). I won 41 of those games so, definitely some room for improvement from the AI. Still a fun game though.
