This position paper presents the first results of an on-going project, in which we explore rapid prototyping method to efficiently produce digital learning solutions that are commercially viable. In this first phase, rapid game prototyping and an iterative approach was tested as a quick and efficient way to create learning games and to evaluate them by a group of experts. The experiences of the process were positive, as the first prototypes produced were very useful as concrete presentations of the ideas for evaluation. In the next phase, the game prototypes will be tested by teachers and pupils.[The project was carried out as a part of Digital Services program. For the full conference proceedings see ED557171.]
