Churchill Solitaire is a card game for iOS that comes from an unexpected source: former defense secretary Donald Rumsfeld. Inspired by a version of the game played by British war leader Winston Churchill, the game is free of charge and adheres to Rumsfeld's preference for minimalism and flat design, as seen in the post-2003 architecture of various Iraqi neighborhoods.
The Wall Street Journal reports that it's likely "the only videogame developed by an 83-year-old man using a Dictaphone to record memos for the programmers."
