### Best of 2015: Shading Puzzles

Here are our best Shading puzzles of 2015. As shading puzzles are (still) our most frequent category with 42 posts, there are five awards this year with just four in the other categories.

Leading off this list is a very neat geometry of cages in this Nanro by Grant Fikes.

This classic Tapa puzzle by Tapio Saarinen with an antisymmetry theme also got a lot of Fave votes.

Hex week was by far our most favorited week of puzzles in 2015, and every puzzle from that week was either a Best of … winner or a close runner-up. In the shading genre, Prasanna Seshadri’s Tapa (Hex) was amongst the best shading puzzles of 2015.

Also from Hex week, this SLICY by Thomas Snyder (a LITS variant) was a top shading puzzle and tied for third for votes across the year.

The best puzzle in this category, and the best puzzle of the year based on number of Fave votes, was this Unique Clues variation of Tapa by Tapio Saarinen. It was truly a special puzzle with many different insights hidden in a quite elegant package.

### Litro by John Bulten

PDF

or solve online (using our beta test of Penpa-Edit tools; use the tab key to alternate between shading and number entry modes)

Theme: Pocket Puzzle

Author/Opus: This is the 5th puzzle from our contributing puzzlemaster John Bulten.

Rules: Variation of standard Nanro rules. Besides the cells numbered 4, identical numbers in differing regions cannot touch along common borders. All “4” clues have been replaced by tetromino letters, and must be connected to form a valid LITS solution (that is, identical shapes cannot touch along common borders). In other words: the final solution, including all numbered cells and tetrominoes, is a valid Nanro solution, and just the regions with tetrominoes form a valid LITS solution.

Answer String: Enter the length in cells of each of the segments labeled with characters from left to right for the marked rows, starting at the top. (Characters include both numbers and letters.) Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 3:30, Master = 5:30, Expert = 11:00
