I nearly didn't post this today, worried that it's been so long since you've heard from me, this might be construed as an April Fool's message. But it's been way, way, way too long since I've given you an update, and it just can't wait another minute!
The puzzle is done, and has been for quite a while... and now, CRUX's computer program to solve it (in Windows, Mac or iPad) is pretty much done too. Both the puzzle and the app need test-solvers, though, and we've been slow to find hardy volunteers. I have, however, heard from at least one satisfied solver who laid hands on an early version and tunneled through the upper half of it without incident.
So I'm making an open call: if anyone is willing to handle the "beta" version of this puzzle, contact me here and we will send it to you. Once we get enough reports, and adjust both the program and puzzle as necessary, we will get you all the "alpha" version.
I am also hard at work on the last reward I promised donors, some time ago: an e-book version of "Callin' Then Squares." It has taken this long because the book has expanded significantly beyond my initial vision for it. It now encompasses virtually every aspect of the crossword-solving and crossword-making experiences I can find, including the classifications of "Callin' Them Squares," but also tournament stories, the rise of Dr. Fill, crossword ethics, industry history, the new crosswordese, crossword-inspired political protests, the Scrabbliest words of all time, and much more. Financial difficulties and other projects have slowed this book's development down, but it should reach top donors later this month, and when it does, I think you'll be extremely satisfied.
At that time, I will also make the book available for download, so if you are not a top donor, you'll still get a chance to read it! (And at that point, I'll be asking you to spread the word, as the book project will have a marketing budget of approximately "pocket lint.")
Between now and then, I'll be releasing a sample segment of the book for general perusal, to whet your appetites. Look for that next weekend!
Thanks for all your patience in your support. The CRUX developers and I very much appreciate it!
