The look has changed! Some of the puzzles that people list for the public get indexed by the search engines (like Google). 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.

Use the "Printable HTML" button to get a clean page, in either HTML or PDF, that you can use your browser's print button to print. This page won't have buttons or ads, just your puzzle. 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!
