Errata

We worked around the printing problem with a technical update to the publishing files which makes the Opening Puzzle images darker. By now, all available copies should be the updated version, but it is possible that there are old copies still remaining in some bookstores or available on the resale market.

If your copy is misprinted, and you bought it new from a bookstore, you should be able to get it replaced. You can also download a page map and use it to fix your copy. The page map shows all 64 pages you need to tear out, along with their page numbers, which is a slight spoiler (sorry about that!). If your pages have light images or you can't find all 64 pages for the Opening Puzzle, you should tear out the pages shown in the page map and then use it to fill in any missing artwork on the Opening Puzzle pages (you will probably need to zoom in to see the images clearly). No other puzzle in the book is affected by these printing problems.

We apologize for any inconvenience.
