QuizUp is a trivia game that tests your knowledge of TV show quotes, world geography, cooking, and hundreds other topics. You can challenge random strangers, or go head to head with your Facebook or Google+ friends to earn more points and level up.
The home screen, shown here, has daily themed topics and your favorite trivia categories.
You get six rounds of questions in each game, and all of them are multiple choice. Some even have photos.
You get 10 seconds to buzz in, and the faster you answer, the more points you earn.
At the end of a game, there's a summary page that shows how many points you earned and your level in that topic. The more points you earn, the higher the level you can reach. Scroll down on this page to view more stats on the match, including the answer to each question.
