All of the puzzles selected by our solvers as the “Best of 2016” are gathered in this PDF. You can read more about them in our other “Best of” posts.

Here are our best Shading puzzles of 2016, now our second most frequent category behind Loop/Path with 50 posts this past year.

Leading off this list was an Easy as LITS variation from Serkan that had a super high FAVE/solve ratio as a patron bonus puzzle. [Note: this is one of two supporter bonuses to win a Best Of award this year, but they’ll stay blurred on this site for non-patrons.]

Prasanna was our shading puzzle master this year, including this surprise of a Nurikabe variation prepared as practice for the WPC with a clean logical theme.

Prasanna also created a new Nanro variation “by accident” this year, which we call Nanro (Signpost). This early Spiral-themed example was well reviewed.

But the two best shading puzzles of this year were a kind of call and response from Prasanna and our audience, based around a “Windows” variation Prasanna experimented with. This Tapa in particular got high scores from the Windows week.

And then inspired guest contributor Jack Lance to make another version, this time with overlapping windows.

Basically tied in votes and clearly connected in origin, these Tapa (Windows) together are the best Shading Puzzle of 2016.

Here are our best Region Division puzzles of 2016, selected from the 39 web posts in this category.

While we didn’t have as many guest contributions in 2016 as in earlier years with the site, there were still some stand-out puzzles from our guests including this magnificent Cave by Bryce Herdt with Fibonacci Spiral theme.

Another Cave, this time a Diagonal variation from Prasanna Seshadri, also got top marks from many solvers.

Carl Worth demonstrated the quality that earned him a contributing puzzlemaster position this year with a tough Fillomino puzzle with a dominoes theme.

The best Region Division puzzle this year though went to this combination of Pentominous and Star Battle by Grant Fikes that gave solvers a unique kind of logical challenge.
