The ‘6DOS’ project is a web application that can be used to demonstrate the principle of ‘six degrees of separation’ as well as to study how people interact with each other through their strong and weak contacts (or close friends and acquaintances).

6DOS has been built to be used in the form of a game. An administrator sets up the initial parameters of the game, such as the number of strong and weak contacts that the players can choose. The players choose their strong and weak contacts from within the group participating in the game. Each player is then assigned a random ‘destination player’. The players are asked to send a message through one of their contacts such that it finally reaches the destination, while also forwarding any messages that they receive, such that each message reaches its own destination.

After the game, the players are ranked based on the accuracy of their decisions in choosing the recipients of their messages from their contacts, and some key statistical measures of the player network and the message flow are displayed. The game can be repeated with different parameters and the results compared.
