The evolution of technologies has allowed that every day more and more games are available on our mobile devices. These games have evolved in many ways depending on their field of application. Thus, one of those kinds of games is pervasive games (PG). Each one of those fields has its own features and targets, which is the reason why researchers have defined pervasive games in many different ways. This is comprehensible from a technical point of view because each research field needs to implement their own properties. In this paper, we present a general overview of the meaning of pervasive games in different areas in order to check and collect their particularities. We also give a conceptual relationship diagram and a general definition that considers the user's pervasive experience found in the results of game experience design.
