Big new feature on puzz.link: You can now solve puzzles together. Just start network play via “File -> Network play” and share the link. It’s quite experimental and likely flaky, but already so much fun that I decided to share it now.
Otherwise, there’s been countless changes since the last update, which I’ve wrapped up in version 0.13.0. Besides various bugfixes and improvements (see the full Changelog), we have a couple of new puzzle types: Araf, Balance Loop, Doppelblock, Maxi Loop, Mid-loop and Simple Loop.
I made some puzzles for the German maths kangaroo prize booklets a while back. Today, they put a set of Slitherlink/Fences/Rundweg puzzles online as part of their offer for kids who are currently staying home due to the virus. You can solve them, too: https://www.mathe-kaenguru.de/zuhause/
Following up the previous Cave, here’s a tougher Nurimisaki. Once you’re comfortable with the type, it might not qualify as “hard” anymore, but if not it will sure feel like it.
That puzzle type switched back to being a shading-first puzzle; I had previously made it an “unshading-first” puzzle for autocheck, but I’ve since changed autocheck for (some / most) shading puzzles to require all cells to be decided before triggering, so the major downside of shading-first is gone.
Here’s a puzzle from my preparation for WPC 2019 that I don’t believe I’ve posted yet. It’s also sort of a practice puzzle for the upcoming first round of the 2020 Puzzle GP, which features the variant Terra XX.
Rules Place numbers in the empty cells, from the range 0-9. Same numbers can’t be adjacent (but may touch by a corner). Wherever four cells meet at a vertex (marked by a black dot), the sum of the numbers in those cells must be 10.
Here’s another Double Choco, probably of similar difficulty to the New Year’s puzzle. I made this one as a “secret solver” present to a user going by the handle “taus” on the Puzzler’s Club chat; the layout is based off their avatar. (There’s a second partial attempt at theming this puzzle that’s a bit less in-your-face.)
Rules Dissect the grid into regions. Each region consists of a dark piece and a white piece; these pieces are connected edge-wise, and they must have the same shape, up to rotation and reflection. A piece may contain any number of clues; these give the size of the piece.
