Here’s a pair of practice puzzles for the upcoming Bulgarian GP.
Rules Solve as a regular skyscrapers puzzle. In addition, all even clues are given. (That is, any missing clues would be odd numbers if given.)
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/
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 little cave I made to illustrate a downside of my recent change to switch the puzz.link solver back to “shading first” for Cave and Nuri-Misaki.
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.)
A puzzle to welcome 2020. This is probably not the first Double Choco puzzle you want to solve.
You can find some easier puzzles in the puzz.link db.
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.
It’s still nowhere near where I want it to be, but I imagine some of my readers are in desperate need of puzzles over the holidays. So I decided to finally announce the puzz.link database – see below. But first:
It’s been a while since I made a proper release for my fork of the pzprjs puzzle applet. Since releasing v0.11.1 back in April 2019, some of the notable changes have been:
Check the Changelog for the full list. Thanks to all contributors, particularly to Lennard Sprong!
At puzz.link/db, you can find an index of publicly shared puzzles from all over the internet. In its present form, it started out as a tool for me to keep up with the flood of excellent puzzles shared on twitter. It aggregates puzzle links (to pzv.jp and puzz.link) from twitter and several puzzle blogs, and lets you track which ones you’ve solved, as well as providing some ways to filter (e.g. by puzzle type or author).
If you miss nikoli.com or croco-puzzle.com, this might help fill the gap. Let me know what you think! I hope it doesn’t fall over from the mass of new users.
