CrossingX is a game for the Apple iPad and was developed for the contest of the 20th international Graph Drawing Symposium. Moreover, it was the focus of my thesis (Touch me I'm a node - A graph drawing related game for the iPad, 2012). and is based on the hierarchical graph drawing algorithm by Sugiyama et al.
Update: CrossingX won the game development contest (19th graph drawing contest) of the 20th international Graph Drawing Symposium in 2012.
The goal is to reorder the vertices (nodes) of a layer in such a way that the edges of an above leaving layer are uncrossed (see the quick start or the how to chapter for a more detailed description).
This game supports the Game Center and a multi-user environment which means that each authenticated (by the Game Center) user has his individual settings, highscores and savegame. For example, whenever a user quits the game the current state is saved and will be reloaded whenever the user re-enters the game, no matter if other authenticated users have played in between.
