We live in a world where co-creation with customers, partners and stakeholders is increasingly common in complex organizational development situations. In terms of gamification, employee motivation, consumer involvement, service design process and collaboration, people want to influence and co-create environments, tasks and solutions (Abril 2007). This case study used gamified service design by employing gamification elements in the design process and used a solution prototyping tool, Comicubes, as a gamification and playification tool to design new airport security services. In the case study described in this paper, 72 Finnish university students of marketing participated in workshops organized in October 2019. The co-creation workshops used the gamified service design approach in combination with customer journey visualization as participants envisioned and designed new airport security services. Our study presents how the students used game elements, such as aesthetics, theme and story, and rewards by co-creating gamified security services, which were envisioned to lead to successful security service experiences.
