                      Jed's List of Situation Puzzles



   "A man lies dead in a room with fifty-three bicycles in front of him.
What happened?"

   This is a list of what I refer to (for lack of a better name) as situation
puzzles.  In the game of situation puzzles, a situation like the one above is
presented to a group of players, who must then try to find out more about the
situation by asking further questions.  The person who initially presented
the situation can only answer "yes" or "no" to questions (or occasionally
"irrelevant" or "doesn't matter").

   My list has been divided into two sections.  Section 1 consists of
situation puzzles which are set in a realistic world; the situations could
all actually occur.  Section 2 consists of puzzles which involve double
meanings for one or more words and those which could not possibly take place
in reality as we know it, plus a few miscellaneous others.

   See the end of the list for more notes and comments.

   The answers to these puzzles are available in a separate file.

1.5.  A man lives on the twelfth floor of an apartment building.  Every

room.  (MH)

Attributions key:

   When I know who first told me the current version of a puzzle, I've put
initials in parentheses after the puzzle statement; this is the key to those
acknowledgments.  The word "original" following an attribution means that, to
the best of my knowledge, the cited person invented that puzzle.  If a given
puzzle isn't marked "original" but is attributed, that just means that's the
first person I heard it from.  I would appreciate it if attributions for
originals were not removed; however, this list is hereby entered into the
public domain, so do with it what you wish.

Notes and comments:

   My outtakes list (items removed from this list for various reasons, most
of which came down to the fact that I didn't like them) is now available from
the rec.puzzles archive server.

   There are many possible wordings for most of the puzzles in this list.
Most of them have what I consider the best wording of the variants I've
heard; if you think there's a better way of putting one or more of them, or
if you don't like my categorization of any of them, or if you have any other
comments or suggestions, please drop me a note.  If you know others not on
this list, please send them to me.
   Of course, in telling a group of players one of these situations, you can
add or remove details, either to make getting the answer harder or easier, or
simply to throw in red herrings.  I've made a few specific suggestions along
these lines in the answer list, available in a separate file.  Also in the
answer list are variant problem statements and variant answers.



Bibliography:

   The game of situation puzzles is also known by a variety of other names:
mystery questions, story riddles, lateral thinking puzzles, mini-mysteries,
minute mysteries, missing links, how come?, situational puzzles, law school
puzzles, quistels (in the Netherlands and other parts of Europe), mystery
puzzles, and so on.  I prefer the term 'situation puzzles,' but I change my
mind every few years when a new term that I like more comes along.  At any
rate, here are some sources for these puzzles, under a variety of names.
Unfortunately, almost all of these books are out of print and extremely
difficult to find.  Try inter-library loan, and be prepared to wait.  I don't
know of any such books outside of the US (though at least the Sloane book is
also printed in Canada, Europe, and Australia), but I'd be happy to include
references to such in future editions if anyone sends me bibliographical
info.
   On this edition of my list, I have included a few puzzles from these books
which I didn't previously have.  I've paraphrased them and cited the sources,
which I hope should be good enough to avoid copyright infringement; however,
I hope to contact the various copyright holders soon and get explicit
permission to include more of their puzzles.  If I fail to get that
permission, a few of the items on this list may go away in the next edition.

   _Games_ magazine (bibliographical data currently unavailable).  They ran a
situation-puzzle contest recently, but I have yet to see any of the results.

   _Math for Girls_ (bibliographical data unavailable).

   Rogers, Agnes, _How Come?_ (1953: Doubleday & Company, Inc., New York).
Library of Congress catalog number 53-5756.  OCLC #1612919.  The author may
also be listed as Agnes Rogers Allen.  With its sequel (see below), the
classic volume on the subject; is probably the original source for quite a
few standard situation puzzles, though Rogers says she does not know who
invented the form.  Nor does she know the source of most of those she
includes -- like all good folklore, situation puzzles are difficult to trace
to their origins.  Unfortunately, both these books are long out of print.
Besides their historical value, these two come furnished with delightful
illustrations of various wrong approaches to some of the puzzles.  These
versions were definitely intended to be read from the book, though; the
puzzle statements are much more long-winded than the versions in my list.

   Rogers, Agnes, and Sheehan, Richard G., _How Come -- Again?_ (1960:
Doubleday & Company, Inc., New York).  Library of Congress catalog number
60-13745.  OCLC #2580602.

   Sloane, Paul, _Lateral Thinking Puzzlers_ (1992: Sterling Publishing Co.,
Inc., 387 Park Avenue South, New York, 10016).  ISBN 0-8069-8227-6.  There's
a lot of overlap here with the rec.puzzles archives, including a lot of
puzzles that I wouldn't even consider doing as situation puzzles (such as the
infamous "12 balls" problem).  Still, it does have one or two nice situation
puzzles in it.  Warning: these are not lateral thinking puzzles in the sense
in which I like to use that phrase -- each puzzle has a definite correct
answer, and creativity and sideways leaps of logic aren't rewarded unless
they result in that answer.  Cover price $US 4.95; should be available (or
orderable) in most chain bookstores in the US.

   _Stories With Holes_ (bibliographical data unavailable).

   Weintraub, Richard, and Krieger, Richard, _Beyond the Easy Answer:
exploring new perspectives through creative problem-solving games_ (1979:
Zenger Publications, Inc., Gateway Station 802, Culver City, CA 90230).  ISBN
0-934508-00-3.  Contains a variety of puzzles and games, most of which aren't
really situation puzzles (and many of which are in the rec.puzzles archives),
plus some creativity games.  Out of print.
