The information causality principle is a generalisation of the no-signalling principle which implies some of the known restrictions on quantum correlations. But despite its clear physical motivation, information causality is formulated in terms of a rather specialised game and figure of merit. The (different) classical and quantum probabilities of winning this game are introduced and discussed, as well as an alternative formulation of the information causality principle.
