Edit: the original images were missing a 2 clue in the bottom right cell of the "door" - fixed now.

I got a little carried away. One puzzle a day? More like one puzzle a week. And I still don't know if I like making puzzles, particularly. So I might not do more.

But it was an interesting experiment: I ended up drawing a picture with the grid, but not with the loop that forms the solution.

Other than some of the stupidly tiny line segments, I'm pretty happy with how this turned out. I managed to include a bunch of the kinds of deductions that I like. So... hrm. Hope it's not too hard, especially if people have only done square grids before... feel free to ping me for help?

Also with the cells having a variety of numbers of sides, I'm experimenting with two-number clues: filled in minus empty.

#SlitherLink #EnigMarch day 1: door.

Here's a fun #Slitherlink puzzle: I like the floret pattern because you have both three- and six-way intersections (so you get to use the "either two or zero lines at an intersection" rule), and the five-sided shapes are more interesting than four-sided ones: cells with a 3/5 clue have some fun interactions.

Anyway. This particular puzzle has a couple nice Jordan Curve theorem deductions (what goes in must come out, so any island has an even number of segments leaving it). Well, the way I solved it, it did. Plus a persistent sub-loop that keeps getting longer and longer.

#Slitherlink puzzles with cairo pentagonal tilings are often fun. Pentagons give a little more scope for counting problems than squares (pentagons with a 3-clue are especially cool), and having both three-way and four-way intersections is cool too.

I thought this one yesterday was particularly good: some nice uses of the single-loop constraint and a long chain of 3-cells, and some interesting bits near the top-right too.

Nat Alison's talk *In Defence of Hand-Crafted Sudoku* at #RoguelikeCelebration yesterday has me thinking about logic puzzles and wanting (again) to try and make a short game that does for Slitherlink what HexCells did for MineSweeper and Nonograms/Picross...

Do it on weird shaped graphs and start from the topology instead of "what happens if these two squares are adjacent?" and carefully ramp up the difficulty so you can figure things out for yourself...

Always more ideas than time.

In any case, I still think there should be more implementations of #Slitherlink on non-square grids. Like https://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/loopy.html#5x5t4:c3d243d2a0b4a33a1d34b24a24a

These are actually pretty boring as slitherlink puzzles, since every border between cells has multiple edges, and there's a lot of tedious counting to 14. But of *course* someone has added spectres and hats to the grid generation for Simon Tatham's Portable Puzzle Collection.

Hmm. Now I'm trying to think: is Slitherlink the only puzzle in the collection that can use non-square grids? It looks like it is...

Vertex slitherlink... or not.
https://thegriddle.net/956

I recently familiarized myself with this slitherlink variant where you clue corners rather than edges, and made some. But then, for a logic showcase, I made one where you have to determine whether a clue is regular or vertex. Link above -- enjoy!

Vertex Slitherlink

Today's batch of puzzles bring a twist to slitherlink by cluing the vertices -- corners of the cells -- instead of the edges.

Catching up on #EnigMarch and I have a puzzle for day 2's 'Nest' prompt: a hornet nest.
