Zen Bound 2 is a great universal app that works on most devices. The game is has beautiful graphics and relaxes you throughout your journey of tying things in a knot. What you do is you get a 3D figure that you can freely move around and tie a rope around. The rope will slowly paint the figure as it sticks on and your objective is the get as much of it painted, percentage-wise, to get to the end. You move up to figures that get trickier and tricker, but it's all in good fun. Great app on the iPad, still great on the iPhone, but it's always better to have a bigger screen for this type of game.
