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.

Cocktail Lamp (easy)

Door Hinge (easy)

Smullyanic Dynasty (easy to medium)

Tetrochain CBT (medium)

Nikoli Omopa #1

    Here is a couple of puzzles using rulesets from the latest PCN "Omopa" sections. If you don't know, "Puzzle Communication Nikoli" is a very big japanese puzzle magazine, and contains a section called "Puzzle Omopa" which is featuring new rulesets that are deemed interesting enough to create good logic puzzles. A lot of the genres popular today came from Nikoli (Slitherlink, for example), and some newer ones were first featured in there (Nanameguri, Choco Banana etc.) Here are 4 small puzzles on RPS Paint, Dancing Loop (AKA Danse and danse in PCN 180), and Tetro Chain CBT. Here are the rules :

RPS Paint : Place some symbols (rock, paper, scissors) in the grid. This adaptation uses circles, squares and triangles.

- Each region contains 2 identical symbols. Symbols in the same region may not share an edge.

- Symbols must be part of a group. Symbols in the same region cannot be part of the same group.

- A group may be composed of 2 identical symbols, or 3 different symbols. This makes the rock-paper-scissors version's groups ties in regards of the RPS game rules.

- Groups may not share an edge.

Dancing Loop : Draw a loop passing through some cells in the grid.

- The loop may only turn 90° or go straight in a white cell.

- Cells with a cross may never be visited.

- Cell with a circle must overlap a straight segment and a diagonal segment.

- Cell with a triangle must overlap 2 straight segments.

Tetro Chain CBT : Shade some cells to form tetrominos (4-cell groups) in the grid.

- A number in a region denotes the number of black cells inside it.

- Tetrominos must not be fully contained within a single region.

- Tetrominos may only touch each other diagonally.

- Touching tetrominos may not be of the same shape (counting reflections/rotations).

- All tetrominos must form a unique diagonally connected group.

Rules taken/reworded from janko.at : RPS Paint Dancing Loop Tetro Chain CBT

    I took the liberty to rewrite the rules, and some part of the instructions were ambiguous. This is my interpretation of the rules, and translating japanese has always been rather difficult (and i'm working with only a tiny example).
