Joachim Bondo released an iPhone version of his mobile chess game Deep Green [App Store]. The $4.99 Chess game was originally released for Apple’s Newton platform in 1998.
John Gruber, a fan of the Newton version, describes the iPhone release (Gruber is a bit of an interface fanatic):
To be clear, this is not a port but a complete rewrite, with the same attention to detail, graphics, simplicity, and fun that marked the Newton version. For example, Deep Green for iPhone lets you move pieces either by drag-and-drop or by tapping a piece, then tapping the square you wish to move it to. (The tapped piece jiggles while waiting for you to tap the destination square.)
Deep Green also lists some notable features for Chess fans:
- Play against engine or human, or engine vs. engine
- Adjustable engine strength
- Concentration setting allows the engine to play more like a human
- Manual board setup
- Playback game (forward/backward, animated replay, drag slider)
- Take back moves (undo, all the way back to start)
- Clean and beautiful user interface
