We now present an analysis of the game data we collected from the users of the ‘Project Waterloo’
Facebook application. The dataset used for our analysis contains 1,883 games played by 685 players.
In 1,027 of the 1,883 games, the players initiating the game did not know the identity of their
opponent. For the remaining 856 games, both players knew each other’s identities. 524 of these 856
games were played between people who were friends on Facebook, and the remaining 332 games
were played between strangers. Examples of some game instances are shown in Table 1. Detailed
demographic data for users is shown in Figure 2.
