Pass It On is a Facebook application produced at TBG Digital for Coral, a legal sports betting parlor in London. Leading up to the Euro's soccer tournament, Coral wanted a way to gain new fans in a quick and fun way. With the Pass It On app, simply pass the virtual ball around to friends and if they pass it back, you're both eligible for prizes. This mechanic got people sharing instantly and increased "likes" by the thousands. Mission accomplished.
