This article is devoted to revealing the theoretical background of dyslexia in young adults to substantiate the chosen approach for mobile learning games. Education in the 21st century has changed just the same as young adult learners; especially those who have some developmental problems, such as developmental dyslexia. If they are lucky to encounter smart teachers, understanding parents, siblings and peers, they succeed in the education system, they reach learning goals and are satisfied with their life quality. If there are gaps between regulations, rules and the real situation, learners lose interest in learning and especially in reading, they do not achieve their learning goals and sometimes they even experience school failure. Educators have to think about new methods, new approaches to diminish the possibilities of failure, to renew interest in learning (and especially in reading) to achieve education goals and to ensure the possibility for better life quality. The article deals with theoretical findings in differences of dyslexia in young adults and the role of technologies and educational mobile games in the learning process.
