#015: Aqre (Arbitrary Regions)
3 June 2022
Encouraged by the interesting logic in the first Aqre (Arbitrary Regions), I set out to create a few more of these. I remember struggling quite a while until I found a symmetric clue placement where all regions could have integer clues.
#014: Diorama (Cipher)
2 June 2022
This is a new genre I created for the Logic Showcase #35 on Puzzlers Club , “Bring Your Own Cubes”. The prompt was to create puzzles on triangular grids that involve partitioning the triangles into rhombi, and optionally interpreting them as an isometric projection of some cubes.

I originally made this mostly as a joke, but it turns out that offsetting the clued regions from the grid that is being shaded actually leads to quite a lot of interesting logic. So consider this just an introductory example puzzle.
#012: Rail Pool
24 May 2022
I created this as a one-off puzzle to celebrate the addition of Rail Pool to pzprxs. It’s medium difficulty and was meant to showcase all features, i.e. question marks and black cells that are not visited by the loop.
#011: Rail Pool — "Quincunx"
11 May 2022
This is one of the hardest Rail Pools I have made so far. This has a reasonable solve path but it’s very narrow in some places. The break-in is very tricky and it’s not all smooth sailing after that either.
#010: Rail Pool — "Minefield"
10 May 2022
It took me quite a while to get this idea to work, so I still can’t quite believe how clean the final clue placement ended up being. This is probably one of my best Rail Pools in terms of both visual and logical theme.
#009: Rail Pool

This was one of the first Rail Pools with question marks. They allow for a lot of interesting logic, and I’m really happy with how the visual theme turned out here.
#008: Rail Pool
5 May 2022
I find that it’s very tempting to put the break-in logic for loop puzzles at the edge or in corners, since those naturally constrain the loop somewhat. In this puzzle I deliberately tried to fight that instinct by only clueing the boundary very sparsely and putting the interesting stuff in the centre.
#007: Rail Pool (Cursed)
2 May 2022
I constructed this when I noticed that my wording of the Rail Pool rules did not specify that the loop had to move orthogonally. It actually turned out as a nice puzzle, but I’m not sure I’d want to deal with this on a bigger grid size.
#006: Rail Pool
1 May 2022
This was the very first Rail Pool I constructed. In hindsight it’s not the most amazing puzzle, but it showcases a variety of basic logic in the genre and I just thought it would be neat to include it for… uh… “historical reasons” I guess.
