A location-based game (also called location-enabled game, geolocation-based game, or simply geo game) is a type of game in which the gameplay evolves and progresses via a player's real world location. Location-based games must provide some mechanism to allow the player to report their location, usually with GPS. Many location-based video games are video games that run on a mobile phone, using its GPS capability.
“Urban games” or “street games” are typically multiplayer location-based games played using city streets and built up urban environments. Various mobile devices can be used to play location-based games. These games have been referred to as “location-based mobile games,”[1] merging the concept of location-based games and mobile games.
