Röda tråden

Röda tråden (English: The Red Thread) was a Swedish television quiz show with Pekka Heino as its host. The program's purpose was for the participants to find "the red thread" in the problem formulations which consisted of a set of pictures with a common denominator. The theme song of the show was Wonderful World by Sam Cooke.

There were three sections to the show: "The Red Thread," including pictures which all had a common feature which the contestants had to figure out. "Letter link" (Swedish: Bokstavslänken) where the letters in a word, one after another, were made visible for the contestants when they correctly answered questions which popped up. The third portion was "Celebrity chain" (Swedish: Kändiskedjan), where pictures of celebrities where linked together with the help of a common denominator, for example the first picture could have been table tennis player Kjell Johansson, the next picture could have then been ice hockey goaley Kjell Svensson, etc.
