Creativity is widely recognized as a valuable trait. The aim of this research is to explore the usefulness of incorporating elements of both game and place into creativity methods, so called design games or gameful ideation methods. The present paper presents findings from a study in which a Gameful Idea Generation (GIG) was conducted. GIG is a collaborative creativity method that draws on concepts from design games and hackathons. We focus on intra-group dynamics in order to gain insights on how gamefulness influences collaborative creative processes. We analyse performance in relation to the level and nature of collaboration displayed during group-based ideation. Our insights provide relevant pointers for the design of future collaborative creativity enhancing technologies.
