The players in the game take on the roles of Churchill, Roosevelt, or Stalin as they maneuver against each over the course of six Conferences that determine who will lead the Allied forces, where those forces will be deployed, and how the Axis will be defeated. The player whose forces collectively have greater control over the surrendered Axis powers will win the peace and the game.

Churchill is a three player game of Coop-etiion where the players must cooperate to win World War II, while at the same time achieving a superior post war position over your allies. If the players collectively fail to defeat the Axis the Allies lose, but if the Axis are defeated, there is a victor of the peace that follows. There is also a two player and solo variant.

Churchill is NOT a wargame, but a political conflict of cooperation and competition. While the game focuses on 10 of the historical conferences from 1943 till the end of the war these and much of this design should not be taken literally.
