There are many puzzle pages about. Many of my pages have links to sites relevant to that particular puzzle. On this page I have drawn together the most important of them, together with some more general links, in no particular order. Some links belong in several sections and so are included more than once.

Pages which are in **BOLD**, have a link back to these pages.
