Gemischtes Doppel 3, the successor to Gemischtes Doppel and Gemischtes Doppel 2, is an unusual German memory-type game in which paired cards may look quite different as matching cards are connected through spoonerisms. Each card in a pair shows a word that is a similar-sounding anagram of the other card's word, with each word being accompanied by its own illustration.
The format originates in "the world's shortest column" (two words ... plus two pictures) from the weekly Süddeutsche Zeitung Magazin. The juxtaposition of incongruous concepts, the odd but perfectly understandable expressions for familiar concepts that often result on at least one side of the anagram, and the deadpan stock photography illustrations are all played for absurd humour.
This sort of memory based on playing with words is more difficult than the usual one. The funny images displaying these words add to the fun.
