Why a Leaderboard?

Before we get into working with leaderboards themselves, it is important to understand why leaderboards are an integral part of your social app or game.

• Leaderboards create a sense of community in an app or game that, otherwise, might not allow your user to interact directly with other users.
• Leaderboards drive users to return to your app in an effort to beat their own scores or their friend's high scores.
• Leaderboards create a sense of goal and accomplishment in an app.
• Leaderboards make it easier for users to share their app experience and progress with their friends, family, and co-workers.
• Leaderboards in Game Center are easy to implement and can make your app quickly feel more polished and finished.
