Leveling up with Quizzer
The starting point
Quizzer is a trivia game to play with friends: sports, movies, music, science, history. The project called for a full community app, cross-platform and multilingual.
The challenge
Fit a real-time multiplayer game, a moderated social network and monetization that complies with Apple's rules into one app, with no hard-coded text strings.
Challenge met
Players compete live, chat and level up in the app, in four languages, with a store listing prepared in 40 languages.
