This is an official photo gallery for Midnight Madness 2015, an epic, all-night puzzle game that took place across Manhattan on August 8 - 9, 2015. Over 250 people participated, and the event raised $3.1 million for the Good Shepherd Services charity. Midnight Madness was a collaboration between Good Shepherd Services, Futuruption, Linked by Air, InsiderNYC, Third Rail Projects, and Elisha Wiesel.

The 1000 photos in this gallery were taken by Lynn Bartner-Wiesel, Mark Chessler, Rachel Elkind, Fred Marcus Studio, Tracis Mcgee, Joshua Schwimmer, and other players and staff. Please click each photo to see links to the photographer's full gallery. Also see these videos by Ben Cheah and Oresti Tsonopoulos. You can also watch the silent video (one of the puzzles) and listen to the game's theme song.

Midnight Madness 2015 was a tribute to Audrey Munson, New York City's forgotten muse. For more information, see these articles in Forbes, Bloomberg Business, Mashable, The New York Observer, The Atlantic, The New York Times, and The Wall Street Journal.
