An educational videogame may sound like the perfect solution to combine an educational process with a fun experience. Even though this holds true in some cases, most of the times educational games do not guarantee positive results in the cognitive development of the player. This is because they are designed to contain educational-related topics but do not focus on the real impact that is achieved on the player. In this paper, we identify different design patterns in the educational videogame “Pueblo Pitanga: Enemigos Silenciosos” and we share the results of applying these patterns and the impact the players. This videogame was designed to create awareness on Dengue and Malaria fever in young kids and teenagers. It was designed and developed by Green Lava Studios for the Pan American Health Organization (PAHO).
