I have now played two different Exit – The Game titles, and they seem all seem to work the same way.
The bulk of it is a deck of cards, made up of Riddles, Help (for each Riddle) and Answers (to each Riddle). There is also a Book, which includes Rules, introduction and more clues to be used in solving the Riddles, and a spinning wheel solver, made up of 3 rings, with a cut out, that reveals a number with each guess of a Riddle.
