Churchill solitaire

. Rumsfeld was taught how to play Churchill Solitaire in 1973, by diplomat , who learned it directly from Churchill. Rumsfeld said that Churchill began playing it during The Blitz in 1940. In a Medium post, Rumsfeld wrote that "there were probably a dozen or so people in the entire world who knew how to play [Churchill Solitaire]", and that he had the mobile game developed in order to preserve it. The variation uses two decks of cards and ten columns, instead of one deck and seven columns (as used in Klondike). It also adds "the Devil's Six", a set of six cards which the player has to place directly into the wastepile and cannot use within the tableau. == Mobile app ==

The Churchill Solitaire app was developed by Rumsfeld, Snapdragon Studios, and Javelin, and was released in 2016. Rumsfeld had previously worked with Javelin to publish his book ''Rumsfeld's Rules''. Javelin – named for the Secret Service code name for Joyce Pierson, Rumsfeld's wife – is owned by Keith Urbahn, who previously served as Rumsfeld's chief of staff while he was Secretary of Defense. Rumsfeld was uninvolved in its programming, though he playtested it. The game is themed after World War II and contains archival footage of Churchill. It is free to download, In 2019, it was removed from Google Play due to depicting tobacco smoking on both the cover and featured footage, being reinstated after the age rating was updated to include nicotine depictions as part of the app's age rating. Churchill Solitaire received positive reviews from critics. Writing for Trusted Reviews, Keith Andrew rated it 3/5 stars, calling it "a solid, if unspectacular, take on solitaire". Brian Barrett of Wired disagreed with its perceived difficulty, calling it "solitaire-plus", though still enjoyed it. == References ==
