  The Interactive Minority Game (IMG) is an online version of the traditional
Minority Game in which human players can enter into competition with the
traditional computer-controlled agents. Through the rich (and, importantly,
analytically understood) behaviour of the MG, we can explore humans' behaviour
in different kinds of market--crowded, efficient, critical--with a high degree
of control. To make the game easily understandable even to those who are
encountering it for the first time, we have presented the game with a rather
simplified interface; in this working paper we explain the underlying technical
aspects for those who have experience with the traditional MG.
