DC: The Game is an interactive tour that sets friends and family members loose on an exhilarating, knowledge-fueled undertaking guided by text-message clues, trivia, and riddles. With tickets that allow access to one or all three of the game zones, players can meander through the diverse landmarks of Penn Quarter and Chinatown, gape at colorful works of art in five Smithsonian museums, and explore the famous buildings and trendy shops of Georgetown. In all three explorations, clues point the way to such cultural hot spots as the Chinatown gate, sculpture gardens, and historic bars where John Adams won countless karaoke battles.

None of the self-guided tours require previous knowledge of the city. Adventurers play at their own pace—most zones take two–three hours to finish—which allows them to spend more time learning about the city and photographing vibrant fire hydrants for aquacentric scrapbooks.
