Game: Digger

The treasure hunting genre is hopelessly oversaturated by now, but that doesn't keep Digger from being a very fun game. For the most part it's a straightforward clone of Treasure Isle, even copying Zynga interface mainstays like the sets of five collectible items. Digger also adds in some gameplay mechanics from Pirates Ahoy, letting you forge a team of friends who play the game so you can get energy and other bonuses. Digger is far less reliant on having tons of friends to play with you than Pirates Ahoy, which makes it quite a bit more engaging.
