This work presents the authors’ experience in the field of mobile technologies, from which several initiatives have emerged. As result of this, a games-based framework for learning has been developed in these last years. This framework is composed by a competition called Mobigame, which has as main aim to stimulate the participation of the students. By participating in this competition participants learn to develop for mobile devices. A game to practice Japanese is also presented in this article, which was presented in the above mentioned competition. This game has been developed for mobile phones or PDAs (Personal Digital Assistants) based on the JME (Java Mobile Edition) technology. Finally, another initiative is also presented: A free download platform of digital contents for mobile devices based on info-educational games.
