One of the earliest forms
Of Interactive Story

2. Early comparisons Game, Story, Novel, Puzzle Poetry (Novak 1991)
“Interactive Fiction is computer gaming’s best parallel with poetry: complex, subtle, and these days, absolutely unsaleable (Guest 2002)

3. Riddle Ancient Dismissed as being a diversion for children.
Riddle is often considered poetry (“Riddle is a short lyric poem that poses a question, the answer to which lies hidden in hints” Turco 1986)

4. Riddle Poses a question Answered by reader or listener or riddlee.
Folk riddles “A riddle is a traditional verbal expression which contains one or more descriptive elements, a pair of which may be in opposition.”

5. Riddle Covered with eyes, but it can’t see.
I tremble at each breath of air and yet can heaviest burdens bear

6. Joke How many Freshmen does it take to screw in a lightbulb?
Response format, not a riddle since they do not describe something that is genuinely to be guessed, but rather provide the set up for a punch line.

7. Other non-riddles
“What’s that thing on top of the engine that controls the mix of fuel and air?
Simply asking for a term, not offered to be guessed but rather in the hopes of learning the answer.

8. Other non-riddles Mathematical problems. Situational puzzle:
A man walks into a bar and asks for a drink. The bartender pulls out a gun and points it at him. The man says, ‘Thank you’ and walks out.
Yes or no questions to figure out why it works

9. Riddles
Meant to challenge the listener but to be soluble, rather than those meant to be insoluble or those not intended to challenge.
Excellent riddles have to be both enjoyably challenging yet soluble with the information provided.

10. Riddles
The unique quality of the riddle as communication is that it engages the attention of the riddlee in particular ways and contains a test for its success. Both parties must be engaged.

11. Mystery novels
Like a riddle but reader doesn’t explicitly need to solve the mystery
Ridlee needs to turn the unknown and unfamiliar into the familiar in order to know the answer.

12. Excellence Must have some agreement between riddler and riddlee.
Author is obliged to pose a riddle that is tantillizing in its opacity, yet fair in the clues it provides.
Riddlee is obliged to solve the riddle, to announce the solution and explain the riddle-question and how each of the clues operate.

17. Poetry and Riddles Principles by Howard Nemerov:
A poem must seem very mysterious.
But it must have an answer (=a meaning) which is precise, literal, and total; that is,which accounts for every item in the poem.
It must remain very mysterious, or even become more so,when you know the answer.

18. Principles
Invite the interactor to solve the riddle, by being enigmatic in a certain way or by presenting something to be solved that is alluring.
Stimulate the curiosity.

19. Principles
2. Provides for the economy of objects in the world. If there are red herrings, they must add to the meaning, even if otherwise extraneous.

20. Principles
3. When the explicit mysteris of an interactive fiction are solved, a work that becomes more profoundly mysterious can be “played” again with interest even when the solution is known.
