This past week of Fillomino puzzles is collected in this PDF and the solutions are in this PDF. If you haven’t had your “fill” of this genre yet, we have more Fillomino in several of our e-books.

We continue to work to improve our puzzle archive. Over the last few weeks, we have added 3+ more years of solution files to old puzzles. All puzzles from 2014+ now have PDFs on the individual puzzles and in the solution packets. We are now working to finish this for our first year 2013 to complete this project. Also, we’ve added Penpa-Edit links for more puzzle styles: Arrow Sudoku, Consecutive Pairs Sudoku, Consecutive Sudoku, and Thermo-Sudoku have been added within the last few weeks. An active list of our completed styles is on our Penpa notes page. By the end of the year we expect “official” supported forms to be posted for most of the puzzles on the site including automatic answer checking.

(Note that we still see some people making their own web versions of puzzles and adding them to the comments. We will only allow these as temporary links if they include the author name and a link back to the site in the digitized form or if we can edit them to add the same; anything else is not in the spirit of our Creative Commons license and some of the outside link aggregators do not credit authors at all which is why we do not want to support links that can separate the author/GMPuzzles from the work. For commenters making their own solving versions, our preference is to use http://gmpuzzles.com/penpa-edit.)

The daily solution videos are on the posts and also linked below. I was playing with a few different notation styles (lines, shading, letters, …) through the week on Penpa, and admit this is one of the puzzles where multiple defaults (and even multiple solution checking options) may be best. Please share your comments on how you prefer to solve Pentominous puzzles and if you could make this work in Penpa. We will probably document all of these methods when we formalize the user experience for this style and for Fillomino.

This upcoming week will feature Statue Park puzzles and will also include a large variation as a Sunday Stumper.

Finally, there are still some minor debugging and optimization steps happening with the fave/solve tracker after the most recent update, including trying to lengthen the time the login is stored. Please keep sharing your comments on how this is working and if all of the solving history has come over from the transfer to the site.

We are excited to announce that The Art of Sudoku 2 is now released in our e-store. This collection of 180 hand-crafted sudoku and variations from sixteen authors was many years in the making, but certainly worth the wait. The entire collection is available for $10 in our e-store, and there are three $4 subsections available: A) = 60 Classic Sudoku; B) = 20 Tight Fit / 20 Consecutive Pairs / 20 Even-Odd Sudoku; C) = 20 Thermo-Sudoku / 20 Arrow Sudoku / 20 Other Variations.

We have been continuing to make some updates to the website. First, on the Penpa side, all of the “classic sudoku” in our archives now have an online solving option. This is the second puzzle, after Kurotto, to be fully digitized, and Star Battle is being worked on now. When we are through with digitizing more styles, we will be reintroducing them here including making some How To videos for using Penpa for these genres.

Also, our solve tracker on each puzzle post has been updated to now be hosted on our site. This update should fix the login problems people have reported over the last six+ months; please tell us if you run into any issues with it, including not seeing your past fave/solve history.
