Donald Rumsfeld releases solitaire app

Politician who once said 'I'm not into this detail stuff - I'm more concepty' says of his solitaire game: 'I've spent countless hours on beta releases'

Donald Rumsfeld, the two-time US secretary of defence who presided over the invasions of Iraq and Afghanistan, has released a video game.

The game, initially released as an iOS app, is based on a version of solitaire favoured by Winston Churchill. The variant uses two decks of cards rather than one, 10 rows of cards instead of seven, and an extra pile of six cards called "the Devil's Six" for the player to work into their strategy.
