The focus of this project are people with Autism Spectrum Disorder (ASD). ASD is characterized by difficulty in socializing. Many apps to support these issues are being developed, but there are few focused on stimulating social collaboration activities between these people. To achieve this stimulus, it is necessary for these apps to have appropriate designs. This work was aimed at designing and developing a multiplayer tablet game in Unity, utilizing the collaboration pattern tool StrateCSA. This tool has three strategies that were translated into levels in the game: cooperation, communication and coordination. Beyond that, the tool was also considered from the developers perspective to identify its potential for creating new apps. Results showed the tool was helpful designing the game, but there is room for improvement.
