50 free Denver trivia questions with answers — geography quiz, new questions added Aug 2026.
Denver was founded by land speculators who named a gold-rush townsite after a territorial governor who had already quit, and it has been outgrowing its origins ever since. It is the only state capital that is also a consolidated city-county, the only city ever to win an Olympic bid and hand it back, and the place where Chipotle, Quiznos and Smashburger all started. These 50 questions cover the whole story: Montana City and Auraria, the confluence of Cherry Creek and the South Platte, the Denver Pacific railroad that saved the town when the transcontinental line went through Cheyenne, Soapy Smith, the Silver Crash, the Carnation Gold Rush, Stapleton and the airport that replaced it, Rocky Flats, the 1972 vote that sent the Winter Games to Innsbruck, and the 2008 Democratic convention. There is geography (the capitol-step benchmark, the 105th meridian through Union Station, the mousetrap interchange), sport (the Broncos, Rockies, Avalanche, Nuggets and Rapids), culture (Red Rocks, the Clyfford Still Museum, the Great American Beer Festival) and the oldest sister-city link in the country but one. Easy questions stick to nicknames and teams; the hard tier asks about mayors, treaties and the hotelier who angled the downtown grid. Every answer is cited to a page we checked and comes with a one-line explanation. Play it solo or print it for a Colorado night alongside our Broncos and Nuggets quizzes.
