Shading Shake #3

    Another compilation of shading puzzles. I included a scraped tapa plus 3 puzzles for this post : Tapa, Heyawake and Kurohappo (rules can be found on the "help" tab on puzz.link or the "rules" tab on kudamono). Hope these are fun (I recommend doing the Kurohappo).

    Thanks to Mender and Rook for testing and feedback on the Kurohappo.

Tapa 1 - Tapa 2 - Heyawake - Kurohappo (penpa+)

Heyawake 🚪 ⬛ 🚪

    Heyawake for today. Since I haven't stated the rules of this puzzle on the blog, I'll put them on this post :

    Shade some cells on the board.
- Shaded cells cannot be horizontally or vertically adjacent.
- A number indicates the amount of shaded cells in a region.
- There cannot be a horizontal or vertical line of unshaded cells that goes through 2 or more region borders.
- All unshaded cells on the board form an orthogonally connected area.

Rules taken from puzz.link - click here for a solved example.

    Today's puzzle is significantly harder than usual, as it's important to find where to look at each step, but does not require any theory. I may put the solve path if anyone is stuck and would like a step-by-step solve.

    Thanks to Menderbug and Wessel for testing and feedback.

Doppelganger Puzzles #1 : Aqre/Heyawake

     Today we are featuring a concept of puzzles that require very thoughful crafting : Doppelgangers (Doppels for short). The concept is simple : A puzzle that can be solved with 2 or more rulesets. So here is a small Aqre/Heyawake doppel. More puzzle of this type will be featured, but it's quite hard to find rulesets that can work together. Yes, the Aqre looks awful, but there is only one crucial step at the start so it's rated quite low.

Shading Shake #1

    Here is a dump of shading puzzles. There are 2 easier puzzles, and 3 you may find very hard (at least calls for heavy knowledge or being accustomed to the genre). The Nurikabe feels especially unfair but I can manage to solve it without too much trial and error (global vision will require to see how regions interact, though). The Heyawake may also leave you stuck at a certain point, and even starting it may be hard : I recommend checking out Teal's guide on solving Heyawakes.
