Some of the puzzles that people list for the public
get indexed by the search engines
Some people find those puzzles and cannot figure out how to make a puzzle
of their own. So this page now has the navigation sidebar.
There are now buttons on the puzzle so that you can get a clean page,
in either HTML or PDF, that you can use your browser's print button
to print. The PDF format allows the web site to know how large a
printer page is, and the fonts are scaled to fill the page.
The PDF takes awhile to generate. Don't panic!
