Guess Who? Puzzles

'''Guess Who? Puzzles''' are 30-second puzzle sequences made up of screenshots of various characters from Series 13 through The Great Race. The images are divided on a 12-piece template and follow a sequence of assembly as an instrumental clip of Thomas, You're the Leader plays in the background. Usually, the featured character's whistle, horn, bell or siren sound plays at the end.

From 2010 to early 2013, the puzzles were narrated by Ben Small for UK audiences and Michael Brandon for US audiences. From fall 2013 to 2016, the puzzles were narrated by Mark Moraghan. The puzzles were often included as bonus features on various UK, Australian, US, Canadian, Mexican, and Latin American DVD releases, and also shown near the end of the US PBS half-hour airings from Series 13 to 20.
