Best of 2014: Shading Puzzles

With new styles Nanro and Kurotto joining Tapa, Nurikabe, Cross the Streams, and LITS this year, shading puzzles are now by far the most common style of puzzle we post at Grandmaster Puzzles (86 total posts in 2014). As a result, we’re going to give out a few more awards for the Best Shading puzzles than in the other categories.

Half of our “April Fool’s” week puzzles got very high ratings, including this Nanro from Prasanna Seshadri:

This LITS puzzle from Palmer Mebane also received a lot of praise for a simple but elegant solving theme:

Tapa continues to be one of our most popular puzzle styles, both in regular form or as a variation. We had three highly rated “best” Tapa puzzles this year. Amazingly, they all ended up using the same general theme. Will Shortz sometimes remarks that “As human beings, we have a natural compulsion to fill empty spaces.” Well, our favorite Tapa all featured impressive empty spaces that solvers would need to fill. Starting the year was this Tapa Triomino variation by Prasanna Seshadri called “Open Middle”:

Then in May came “Open Spaces” by Murat Can Tonta:

Then in October, perhaps inspired by what came before, John Bulten provided “White Hole”:

While really a hybrid of a shading puzzle and a loop puzzle, Serkan Yürekli’s Nurikabe Loop “The Magic of 23” had the magic to make this list:

Finally, we had some noteworthy Cross the Streams puzzles. Murat Can Tonta used a lot of just four basic clues in this masterpiece:

But the best Shading puzzle, and the last of the puzzles tied for Puzzle of the Year (with the TomTomTom, and the C Major Cipher Fillomino) was Grant Fikes’ audiobook form of a Cross the Streams puzzle. There isn’t really a puzzle to show here, just an MP3 link for you to hear.

All of the Best Shading puzzles for 2014 have been gathered in this PDF.
