The Redistricting Game, an early serious game to teach the basics of redistricting, was a produced by USC’s Annenberg Center and The School of Cinematic Arts Game Innovation Lab. The game effectively simulates the complex processes of congressional redistricting, beginning with a responsive 2D map-drawing puzzle, followed by role-playing to usher the map through the legislative and judicial branches of government.
The Redistricting Game was officially launched in June 2006 in the U.S. Capitol Building with Representative John Tanner and ex-Senator John Anderson, both proponents of redistricting reform. As far as I know this is the first digital game to be launched in the halls of the US Congress.
The game has been available online since 2006. Play The Redistricting Game at www.redistrictinggame.org
