Foursquare is a location-based social network (LBSN) that combines gaming elements with features conventionally associated with social networking sites (SNSs). Following two qualitative studies, the paper sets out to explore what impact this overlaying of physical environments with play has on everyday life and experiences of space and place. Drawing on early understandings of play (Caillois, 2001;Huizinga, 1992), alongside the flâneur (Benjamin, 1991) and 'phoneur' (Luke, 2006) as respective methods for conceptualising play in the context of mobility and urbanity, the paper examines whether the suggested division between play and ordinary life (Apter, 1991;Caillois, 2001;Huizinga, 1992) is challenged by Foursquare, and if so, how this reframing of play is experienced. Secondly, the paper investigates what effect this LBSN is having on mobility choices and spatial relationships. Finally, the novel concept of the 'phoneur' is posited as a way of understanding how pervasive play through LBSNs acts as a mediating influence on the experience of space and place.
