The game can be classified as both a serious game and a global warming game. In Keep Cool, up to six players representing the world`s countries compete to balance their own economic interests and the world`s climate in a game of negotiation. The goal of the game as stated by the authors is to "promote the general knowledge on climate change and the understanding of difficulties and obstacles, and "to make it available for a board game and still retain the major elements and processes."
