Besides pure entertainment, games can provide valuable input for social interaction, learning, etc. Recently, new pervasive game genres have been developed, including mobile games, tangible games, table-top games, exhaustive games, mixed reality games, etc. Pervasive games extend the traditional game experience by supporting natural contexts within game experiences. In this paper we present ECHOES as a new mobile pervasive multi-player game which is played outside the boundaries of a building. ECHOES combines the classic features of hunting games with the logic of riddles to create a fun and exhaustive experience in a city.enText/Conference Paper1617-5468
