We have just released CardShark for Android, a casual card game previosly released on iPhone to a high user reviews.
CardShark combines a silky smooth 3d presentation with tasteful animation, sounds, and an elegant drag-drop interface that has been lovingly fine-tuned for the touch screen. Touches and drag targets are forgiving, and piles are automatically split following completed gestures. Touching foundation piles will automatically complete a game.
