There we go, the last of the series. Of course, the blog is turned off again for the moment, at least until I manage to construct more puzzles. I’m busy too, you know. (By the way, expect things.) Answer key would be “lengths of horizontal segments in row/vertical segments in column” for R1/C2 (or R2/C1 or something).
Another difficult “opening”. Also for some reason I find sudden interest on Pure Loop and Heteromino now, like exploring two untouched lands… (Okay, I think I see it being used in more things now, but still.) Did you know that Heteromino almost got into FAST (as an uninteresting 3×3), but Deb decided it was too obscure and got replaced with Kakuro, which in turn also got replaced by Next Term? The more you know.


Well, will you look at that. And I thought I knew everything about this type. Note to self: cover this in the book! – ZM
