EA Sports has teamed up with car-hailing service Uber for a new Madden NFL 16 promotion where riders can get a free copy of the professional football game and even a new Xbox One.

　　Starting today, August 24, Uber riders in all 32 NFL cities--including New York, Boston, Chicago, and San Francisco--can unlock the "Madden NFL" vehicle view in the Uber app by entering a special code. Once you do that, if one of the specially marked cars is available, you'll get a free copy of Madden NFL 16.

　　Uber says in a news release that demand for these cars will be "very high" and there is no guarantee you'll get a free copy of Madden NFL 16. Copies will be given away on a first-come, first-served basis.

　　In addition, one rider from each of the 32 cities will win an "Xbox One ultimate prize pack," which comes with a new console, a copy of the game, "and more," Uber said. This prize pack will be delivered to you by an NFL player from your city's team, possibly a player from the recent "Madden: The Movie" trailer.

　　Madden NFL 16 launches on August 25 for Xbox One, Xbox 360, PlayStation 3, and PlayStation 4. Xbox One owners with an EA Access membership can start playing the full game right now.

　　Below are the participating cities and their respective codes:
