This study investigated the developmental process of a dynamic geo-game, Gezgin, which was developed by the researcher based on the Four-Component Instructional Design (4C/ID) Model, and its benefits in the acquisitions, values and skills of the Global Connections learning area of the social studies curriculum applied in Turkey. It also determined Gezgin's reflecting acquisitions, values, and skills, as well as social studies education experts' opinions about Gezgin. A case study approach was adopted and five experts participated. The data collection lasted for approximately fourteen months due to the development process of Gezgin. Most of this process coincided with the COVID-19 pandemic period. The data were descriptively analysed and the experts' evaluations were subjected to content analysis. Findings indicated that Gezgin mostly reflected the acquisitions, values, and skills of Global Connections learning area and could support the curriculum as a studying environment, create various experiences, materialise theoretical knowledge, and that it could be tested on students. It was also understood that values, primarily, and skills and acquisitions, subsequently, were mostly supported. Although the results of the study revealed similarities with the results of other studies in scientific literature, it differed from them as a large platform where the acquisitions, values, and skills of a learning field were reflected. The results indicated that geo-games should be used to support other learning areas, develop high-level skills, and create a level of awareness in accordance with spatial citizenship skills.
