Door Hinge #2

      A chill Door Hinge for this post. Rules here. It seems weird that the grid looks like how a Heyawake is set, no ? Maybe it's just me.

    Thanks to Wessel for testing and feedback.

Door Hinge 🚪

    Door Hinge (Chiyotsui in japanese) is a shading puzzle that cleverly uses region borders as clues. This puzzle type was covered previously here. Here are the rules :

Shade some cells on the board.

- A group of orthogonally connected shaded cells is called a block. Each block is cut exactly once by a single straight segment of region borders, across which it must have reflectional symmetry.

- Numbered regions must contain the indicated amount of shaded cells.

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

   The name comes from blocks of blacks cells behaving akin to door handles as they poke out the door from both side at the same point with the same shape (thus the reflection across borders).

Shading Shake #2

     Another Shading puzzle pack for you. I tried to reach for lesser known genres, and kept the difficulty to a maximum of "medium" (as opposed to the first post lmao). Smullyanic Dynasty was found on Zotmeister's blog, and I will assume he is the creator of the genre (meaning the first puzzle with these rules). Since Tetrochain CBT was already shown here, I won't cover the rules again, but Smullyanic Dynasty deserves a quick explanation (the rules witten on Zotmeister's blog are way too long, so I reworded them to get straight to the point.) Hope you find these puzzles enjoyable.

    Smullyanic Dynasty rules :

Shade some cells in the grid.

- Shaded cells may never share an edge.

- Unshaded numbers indicate the amount of shaded cells in all 8 surrounding cells.

- Shaded cells must indicate a different number from the amount of shaded cells on the 9 cell-square centered on itself. See shaded numbers as liars in regards of the counting shaded cells rules, but counting itself.

- All unshaded cells must from a single orthogonally connected group.
