The popularization of digital games reaches a wide diversity of audiences and styles, but often do not take into account the accessibility context, which excludes a portion of the population, such as children with disabilities. There are studies presenting games with customized interaction options; however, generally thought for specific disabilities. The purpose of this research is to investigate customizing characteristics in games, allowing a specialized professional to tailor the game to a specific patient during their session. For this, we conducted a review of the literature on adaptable games and an empirical study where we investigated three games that were developed and tested with healthcare professionals specialized in the care of children with disabilities. The results generated a set of customizable features for adaptable games.
