We’ve also recently uploaded a new version of Penpa-Edit (from 2.26.18 to 3.0.3) with several quality of life improvements. A big one (that we will highlight again in the future when we have an appropriate week) is that coloring of regions now works like drawing region boundaries for solution checking purposes in Fillomino, Pentominous, Araf, and other puzzles. As long as everything is colored (i.e., not white) and edge-adjacent regions are a different color, they are marked as implicit edges and compatible with checking. This update also includes some improvements to the top interface sizing that maintains the size (rather than moving up and down) when shifting between tools, better keyboard support for Sudoku movement in hex/cube modes, and several others described in the change history. Thanks to Swaroop and the other developers for these improvements.
or solve online (using our beta test of Penpa-Edit tools; use tab to switch between edgex mode where left click+drag draws lines and right click marks X’s, and a shading and number entry mode to mark/update the liar clues.)

This week we crossed a milestone with over 2,500 puzzles posted on the web. Alongside this huge number, which has still never included a broken puzzle with 0 or more than 1 solutions, we finished posting solution PDFs for all of our earliest puzzles from 2013 so every web week now has solutions available. We also now have Penpa versions for almost every major style (2350+ puzzles) and mainly have one-off variations to still digitize. So by the time we hit our 10-year anniversary at the end of this year, our archive will be in great shape! If you’ve appreciated our content through the years, please consider buying some of our books (all with original puzzles) or making a donation to help support the site and our authors.
6 of our 2,500+ puzzles coming from this past week, which featured the number placement styles Smashed Sums and Terra X, are gathered in this PDF and the solutions are in this PDF.

This next week will feature Slitherlink and variations, including a Sunday Stumper in one week’s time. Next Sunday we will also be releasing the new book Slitherlink and Variations 2 by Matej Uher, so look forward to a week+ of getting thrown for a loop.
