Hi, back when the Wordplay documentary came out there was a companion website at http://www.wordplaythemovie.com/
that included the usual promotional information, but also a couple of bonus puzzles.
I vaguely recall that they were downloadable as PDFs or perhaps PUZ-formatted. Or maybe you could only play them on the website.
I have the companion book, but I have a nagging sense that there were some additional puzzles that were online exclusives. I don't suppose anybody has packratted those files away somewhere?
