In this paper, we consider mobile game playing from the perspective of social network analysis. A multiplayer card game (BELKA) has been designed. The game allows players to select between trading, playing or pairing with other players. The game was played using playing-cards or using HP Ipaq devices equipped with Bluetooth, and players were either seated around a table or encouraged to move around the room. Activities during play were recorded and these data are analysed in terms of social networks. It was found that while the playing-cards led to attempts to apply the same type of activity in both seated and mobile conditions, the use of PDA led to differences in play. These differences were due to both technical, i.e., availability of players in the Bluetooth network , and social, i.e., visibility of players in the world and the activity of the Dealer. It is proposed that the manner in which the game was played changes when a mobile device is used whilst moving around, and that this is different to when the same device is used when sitting down.
