domino logic puzzle
Andrew Nikitin
I have come up with yet another logic and deduction puzzle.
Here the tileset is assumed (standard dominows set) and clues are hidden in
a configuration itself.
Configuration also can be printed and attempted to solve without a computer.

I would appreciate any kind of feedback.
(It is wrtitten in javascript for ms internet explorer, I beg my pardon for
that from non windows people).

Since JavaScript is supported by many browsers on many platforms, one
wonders why this only works in windows IE. For example, I run IE on a mac.
You're right, you're script doesn't work for me. But I wonder why. I run
plenty of other JavaScript stuff.
Please support my new e-mail sponsor.

I remember this game from the Martin Gardiner book you reference, and I did
love it then. My only problem with it is that it doesn't check for
uniqueness of the solution - my first try had the following in the
bottom-right corner:
4 6
6 3
(elsewhere, the same pattern appeared with 41/13 and 05/06)
But still - a lovely game and very nicely done.

I noticed that his source code does not have a language attribute
script language="JavaScript"
The first Javascript I wrote would not run on a Netscape browser
because I foolishly followed Microsoft's reference manual and had
language="Jscript". Of course, IE worked fine when I changed it
"Javascript". You have to use "Javascript" if you want compatibility
across browsers. And if you look at web pages on Microsoft's own
sites, you'll find out that they use "Javascript" in their own stuff.
I don't know what happens if you omit the language attribute
altogether, but IE has a history of being forgiving of invalid syntax
in an attempt to make their product look better. "Works best with IE"
means this page is so poorly written that any proper browser would
reject it, so use IE.
And since there is only one way to do things right but infinitely many
ways to do things wrong, it wouldn't suprise me if various platform
implementations of IE have different rules of stupidity.

I call these "Alex Knight" puzzles since he is the author of several
which appeared in Dell Logic Puzzles magazine.
I wrote software to generate such puzzles. That's easy, but mine
would produce puzzles at various difficulty levels (some are very easy,
some *very* hard without computer) and with solutions relying on
different, user-specified, types of deductions.
If there seems to be interest, I'll post some of the puzzles I
generated. Just ascii, no Javascript.
The generation software is rather involved, and "not ready for
prime time."

Nevertheless you should leave the style sheet you are using
where the server tries to find it. My Browser complained that
was not on the server. A look at the source code confirms this:
<link rel=stylesheet type=text/css href=../g.css />
so you should indeed put the style sheet on the server as well
for us to be able to load what you set up.

Andrew Nikitin credits, through Martin Gardner's "Mathematical Circus",
Lech Pijanowski with the invention of this game. I don't have that 1979
book, so I can't check up on it; what I do have is a small booklet
printed in 1924 in Germany, which claims that the game was invented in
1874 ff., patented 1893 (German Reichs-Patent-Nr 71539) bei Richard Osa
(Pseudonym for O.S. Adler) and published by same in 1894 under the name
of "Dominosa" (but reportedly sold badly since the game was yet
unknown). The game was included in "Kürschners Jahrbuch" (almanac) in
1899, and in 1912 the first edition of my booklet "Sperrdomino und
Dominosa" was published in Züllchow bei Stettin by "Verlag der
Züllchower Anstalten", an educational institution.
Assuming O.S.Adler has priority, this type of puzzle should be called
"D o m i n o s a o m n i b u s", being one manner of playing Dominosa.
"Triplet Dominosa" uses a 36-piece Domino set (ranging from 0:0 to 7:7),
and aims for triplets - three squares of equal value in a row.

Google spits out soem more links, but since I don't speak any eastern
european language, these are greek to me. Andrew?
2 Dominosa puzzles from my booklet by O.S.Adler and Fritz Jahn:
Puzzle 1: Using a domino set of range 7 (36 pieces), can you make a
rectangle which is entirely made out of triplets?
Puzzle 2: (front page) How was this cross formed?

<http://home.fuse.net/anikitin/domino.htm> are not very good.
I have had some domino puzzles published in _Dell_Logic_Puzzles_
(one of mine was the first such to be rated four stars) and the Games
Cafe (a now-defunct website intended as a companion to the Chess
Cafe). In my view a good puzzle of this kind should have a unique
solution and no domino with a unique initial location. (A few years
ago I published a puzzle in which every domino had exactly three or
four possible locations.)
I was also surprised to see the remark that Martin Gardner credited
the puzzle's invention (in _Mathematical_Circus_) to Lech Pijanowski.
A friend, Steve Wilson, who has designed these puzzles for years,
says that the game dates to Edwardian times at least. Michael
Mendelsohn gives a reference back to 1874. M.C. is one of the few
Gardner collections (from Scientific American) I don't have, so I had
to locate a copy elsewhere. It turns out that Gardner merely
mentions that he learned of the puzzle from Pijanowski (best known
as the inventor of the deductive game LAP which appears in
Sid Sackson's _A_Gamut_of_Games_); he does not say that
Pijanowski invented it..
