Badges are awarded for successfully completing Community Challenges. You can earn one by completing a streak, target or journey challenge or finishing in the top three of a leaderboard challenge.
You can also earn unique, limited badges through special Community Challenges.
All your badges are displayed in your trophy case for you to brag about them to all of your friends.
*Unfortunately, badges aren't awarded for private challenges. So get out there, join some community challenges and make some new friends!
