Carcassone

Already a classic board game in its own right, the iPhone adaptation of this tile-based strategy game was one of the most beautifully executed in the App Store. A new update has added native iPad compatibility, thus it's earned a spot on our list. Online and local multiplayer and a weekly solitaire puzzle challenge add up to a ton of replay value, and in-app expansions mirror more-expensive sets available for the actual board game. If you're board game apprehensive, don't worry: while Carcassone can take a little getting used to, it's a more worthwhile iPad game to own than Catan -- and it's great for pass-and-play multiplayer.
