We just released our latest Starter Pack book, Starter Pack 4: Slitherlink by Takeya Saikachi. Like our other Starter Packs, this book contains a great set of elegantly hand-crafted easy-to-medium difficulty puzzles to get started with some of our different puzzle genres. Slitherlink is a loop puzzle style with a lot of depth of logic stemming from its very simple rules, and we’ve featured it a lot on this site. Like our other Starter Packs, all of the puzzles in this book also have a penpa link for digital solving. This book is also the first time we have saved penpa “solving animations” for each puzzle, so you can watch step-by-step how someone can go through the puzzle to get to the final answer which may help solvers know where to look when they get stuck. We are planning to bring Penpa solving tools and these solution animations to more of our upcoming titles, so please share your feedback here.
The new Starter Pack book connects to our most recent “Starter Pack” variety mix week of puzzles which included a Slitherlink by Takeya. Those puzzles are is gathered in this PDF and the solutions are in this PDF.
The daily solution videos are on the posts and linked below:
In the background we’ve been continuing our project to digitize our full puzzle archive for Penpa solution modes. All Sudoku puzzles of any type as well as all Skyscrapers puzzles have now been covered. This week we expect to finish Minesweeper and Battleships too. This will leave us with only a couple main genres and five “Other” categories to go to get nearly every puzzle in our soon-to-be ten year history available for solving in this mode.
This coming week features two different Number Placement styles that I often connect with the World Puzzle Championship: Smashed Sums (aka Doppelblock) and Terra X (which I first saw in 2019 at the last live WPC).
