or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)

Theme: Clue Symmetry and Logic

Author/Opus: This is the 16th puzzle from guest contributor Murat Can Tonta.

Rules: Standard Tapa rules. Also, the shaded region must be able to be split into tetrominoes to form a valid LITS solution (meaning all tetrominoes are connected but no two tetrominoes sharing an edge are the same shape, including rotations and reflections).

Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 12:00, Master = 25:00, Expert = 50:00

Theme: Logical

Author/Opus: This is the 7th puzzle from guest contributor Tapio Saarinen. You can find more of Tapio’s puzzles on his blog.

Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

Author/Opus: This is the 63rd puzzle from our contributing puzzlemaster Serkan Yürekli.

All the variety puzzles from the first week of 2015 can be found in this PDF.

This next week will be a little harder than usual, with a lot of interesting Tapa puzzles and variations. Puzzles will be by Prasanna Seshadri, Serkan Yürekli, Tapio Saarinen, and Murat Can Tonta.

The bonus puzzle for our high-level supporters will be a Tapa (Borders) by Serkan Yürekli.

The advertised “stats” update for 2014 will be coming later, but I did want to follow up on several requests from readers for the new year.

– I’ve already posted about our site navigation changes for 2015 but I wanted to mention again the new sidebar/”posts by category” and “posts by author” bits and make sure solvers are finding this to be an improvement.

– We received many requests for a way to distinguish the PDF files in a week as they sometimes get mixed after printing; we’re now adding the posting date to the top of all PDFs in 2015 which should help track things better.

– The biggest open ticket to address is a way to track the puzzles you’ve solved. Here I have to rely on our web developer at the moment so I can’t promise you any timeline, but I hear the request loud and clear. We’ll work through the challenges of merging the solving data with a representative calendar of our site posts and have something available as soon as possible.

– We’ll be adding some new puzzlemasters this year, but I won’t tell you who or when yet. That will be a surprise.

– Also on the horizon for early this year are some improvements to our estore, including more titles there (that only our patrons have seen), and a new header for the blog.

Now that we are doing so many things with daily puzzles and monthly ebooks and other collections, it is time to bring on some more freelancers to help with the site and with our books. There are projects that simply cannot move fast enough because I don’t have the time to complete them myself. Our most pressing need is for an artist that can create covers for our book collections. We’re looking for clean, professional art that showcases how special our puzzles are, with our The Art of Sudoku cover being a prime example. If you think you might be the person to help us with that, please contact us.

PDF

or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between ship placement and shading modes. In ship placement mode, right click gives sea, left click gives circle/square, left click and drag for rounded ships.)

Theme: 2014 to 2015

Author/Opus: This is the 214th puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Standard Battleships rules. Use the indicated fleet. (Variable shading of numbers is for artistic purposes only)

Answer String: For each row from top to bottom, enter the number of the first column from the left where a ship segment appears (enter just the last digit for any two-digit number). If the row is empty, enter 0. Enter these numbers as a single string with no separators.

Time Standards (highlight to view): Grandmaster = 4:45, Master = 8:45, Expert = 17:30

Solution: PDF; a solution video is available here.
