Advergames are a promotional tool that confronts children with brands in an entertaining and playful setting. The present study adds to the existing knowledge by analyzing an advergame placement that is usually not targeted at children: credit cards. Based on an emotional conditioning process premised on the positive gaming experience, we argue that advergames lead to an increase in brand evaluation and brand choice. In addition to changes in brand outcomes, we investigate how playing a game promoting credit cards can impact children's spending behavior. For that purpose, children either played the traditional version of Monopoly paying with cash money or they played the banking version, promoting Visa credit cards. Results indicate that exposure to the branded game enhanced preference for Visa. In addition, children's spending behavior increased in an online shopping task. As another important contribution to the literature, we found the behavioral and attitudinal effects to be independent of children's age. In light of young consumers' high debt, our findings raise concerns about targeting children with credit card placements in advergames. Copyright © 2016 John Wiley & Sons, Ltd.
