Abstract. While companies, universities, citizen and governments become aware about the Sustainable Development Goals, they are confronted with challenges as well. How to set the goals, how to agree on priorities, how to convince everyone, how to mobilise employees or advocates ? That is where our specifically designed methods and gamified tools help stakeholders turn SDGs intentions into action plans. This article relates our experience and gives a taste of our magic recipe and ingredients. Simple game rules and an inclusive climate of trust; openly oriented towards co-construction. These basic principles are the fundamentals of our innovative, inclusive and participatory approach based on the establishment of a permanent dialogue between populations and technical agents, on mutual respect and the principle of partnership, as well as on the recognition of local know-how. We use the concept of boundary objects as a foundation for the pursuit of a common goal and help to minimize or avoid conflicts. Our playful approach combined with our games made of natural materials allows us to highlight the multi-sensory dimension of the experience we offer. By stimulating all the senses, everything makes sense!
