This present research relates to location based mobile games.In such games, players have to perform tasks with regard to their geographic location.An operational and technical method using the players real time physical movement information is proposed to generate the virtual social interactions.The game interface can be a mobile telecommunication device with a digital screen using GPS or any other geo-localization device to assess the movement of the player.The game interacts through the mobile device with a server that is used to put into relation several players who can thereafter either accomplish game related tasks in the real world or compete to complete a game related task.An implementation of this technique is proposed to illustrate the use of current technologies in developing a multiplayer location-based mobile game.
