The Celtics launched a Facebook game called 3-Point Play to build engagement with fans and collect marketing data. The game allowed fans to predict Celtic's games and win tickets by outscoring friends. Over 50,000 local fans were added to the Celtics database through playing during the regular season and playoffs. While ticket sales through the game were modest, it proved Facebook fans will engage for prize chances and validated Facebook as a marketing channel. Lessons included the need for support against changing Facebook rules and bugs in even simple games. Future steps could include mobile apps, broadcast integration, and sponsorships.
