Quiz game Trivia Crack is winning the hearts of Millennials as it soars to the top of App Store charts. The game is gaining popularity around the world, especially on school and college campuses, resulting in 100 million users and a steady 800,000 daily downloads. The set up of the game is basic but addictive: the user spins a colorful wheel and then answers questions from one of six classic quiz categories. Users can challenge friends on Facebook, but what really sets the app apart is that players can submit their own questions to contribute to the game, keeping the question pool “new and relevant.” In Argentina, where Trivia Crack launched, the app is also available as a board game and a TV game show is now airing.
