Trivia Crack

Incredibly addictive, Trivia Crack is one of the recent social apps to hit the market. It allows you to challenge friends or strangers to a quiz challenge. Once in a challenge, answering questions correctly works you towards winning a character that corresponds to one of the app’s six categories: science, entertainment, art, geography, sports and history. The first to win all six characters wins the match, but you can try and steal characters to get back in the lead. All the questions are crowd sourced, so you can come up with your own and submit them to the app. With millions of users all over the world and over 100,000 questions, Trivia Crack will keep your boredom at bay.

Available for free on iPhone, iPad, Android, Facebook and Windows Phone.
