Great if you only want to play against the bots; lousy otherwise

If, however, you wish to play against a friend, you may be out of luck. As other reviewers have noted, the async option (through Game Center and the apps native game network) barely functions. It is prone to locking up, long delays, and crashing the app. In addition, the app has lost games. To whit: I started a game with a friend; we each took a few turns. And now, despite a badge on the app icon and a notification in Game Center assuring me that I have a game, the menu shows no current games and therefore cannot load the game. Id avoid purchasing this app until the issues are resolved by the developers...
