Zen Bound is a puzzle game for the iOS, Android, and Maemo platforms (Nokia N900), developed by Secret Exit. It was announced on September 5, 2008 via the company's discussion board, and officially released via the App Store on February 24, 2009, and via Ovi Store on June 16, 2010. A port to Android was announced as part of the Humble Bundle for Android 2 on March 19, 2012. The game has received press attention for its unique gameplay. A lite version of the game was also released for free which featured 2 levels of the game.
The goal of the game is to paint various objects. In each level the player is given an object with an attached rope which varies in length depending on the level. Using a mouse or touch screen and tilt controls, the player attempts to wrap the object with the rope. Each time the rope is laid down on the object, the area near the rope gets covered by paint. The challenge is getting the required percentage of an object painted with only a finite length of rope. There are three targets in each level - minimum, medium and maximum coverage.
Some levels require nails protruding from the objects to be entwined in rope rather than having to cover the object's surface.
