Smartphones and tablets lead sales of electronic devices around the world and offer a rich field to explore gaming initiatives. Mobile media created a ludic ecosystem in which large publishers and small studios coexist; the new ways of digital content distribution allowed a gaming market with big productions and indie experiments to live in the same platforms. In this scenario, we want to analyse a development process involving an independent Brazilian mobile game named Dominaedro, launched by Ludofy Studio in 2014. Our focus in this work will be to discuss iterative design – a design methodology based on a cyclic process of prototyping, testing, analysing, and refining a work in progress. In this context, we understand iterative design as a methodological tool to create a game. We intend to observe this kind of development process, emphasizing the analogical prototyping phase that gives us feedbacks from the beta-testing players, as in a qualitative research. Finally, we present the importance of the iterative design to quality assurance in the digital version of the game. Data collected through 20 beta testing sessions showed the importance of iterative process to improve a gaming experience and to facilitate the production of the digital product. Based on this content we will demonstrate the whole process of creating a mobile game – from the idea, through the prototypes, until reaching the final version. We conclude, highlighting the current tendency to create indie games using accurate design methodologies to gain audience in a very competitive scenario, and how indie games could be a learning point for aspirational game designers and small publishers; we will also emphasize the importance of using digital social networks and specialized media to publish and support an independent game.
