  School classrooms are equipped with more and more mobile devices. However,
the latest studies show that their use by teachers is still very limited
because of a lack of resources and applications adapted to use these artifacts
in education. Among the new directions of use, research conducted on Mobile
Learning Games (MLGs) seems very promising. In this article we propose to
identify the MLGs from the most referenced research articles and that have
proven their value in educational context, in order to determine their features
and impact on learners. This study will then allow us to define the common
characteristics of these MLGs and identify the main problems that occur when
they are used by teachers.
