By late 1942, the Axis had been stopped at Stalingrad, El Alamein, and Guadalcanal. With Axis expansion halted and Allied victory only a matter of time and resources, Churchill, Roosevelt, and Stalin began to focus on how to shape the ensuing peace to their advantage. Churchill is a game about the inter-Allied conflicts that occurred over the Conference table as each side vies to control the Allied agenda and the course of things to come.

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-etition" where the players must cooperate to win World War II, while at the same time achieving a superior post-war position over their 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 game of political conflict and of cooperation. 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.
