Zen Bound and Zen Bound 2 for the iPad and iPod touch is a great game for someone that is learning to use the iDevices touch controls. You start with a block of wood that has a string attached to it. Using the touch screen, you manipulate the block of wood to get the string wrapped around it. As the string touches new areas of the wood it paints it. The object of the game is to paint as much of the wood as possible with as little string as possible. The game progressively gets harder with different shaped blocks of wood and shorter and shorter amounts of string.
