This paper explores the integration of social networks with crowdsourcing games for generating archival metadata. We studied crowdsourcing, gamification and social dynamics from the perspective of cultural heritage and combined their features in a metadata game prototype on the Facebook platform. We tested our prototype and evaluated its results by analysing participation, contribution and player feedback. The two-week testing phase showed promising results in terms of user engagement and produced metadata. We conclude that deploying metadata games on social net- working platforms is a feasible method for digital archives to harness human intelligence from large shared spaces.
