The paper gathers the current knowledge and trends in educational escape rooms and co-design practices, linking them to the discussion on the application of these two concepts in the context of participatory game design. It explores the benefits of applying an escape room experience to reflect on cultural identity while indicating the benefits of the application of co-design methodology to develop such an experience under inclusive conditions. In this paper, we propose a framework to co-design educational escape rooms, based on the experience from the project The Inheritor - the development of an edu escape room to explore cultural identities. As an outcome, we explain pragmatically the main stages adapted from the co-design methodology enriched with game design elements. We explain the roles of the co-designers that emerged during the process and propose a framework to co-design escape room experiences with them. The area was particularly challenging due to references not only to the existing systems and connections but also to the past events and social relations that influenced the current perception of the “cultural self”, which we aimed to address within this framework.
