Rules:

The puzzle consists of thirteen 10x10 grids. Each grid follows the standard rules for a particular shading puzzle genre. Nine grids contain regions, and these grids overlap with four grids that do not contain regions. Where two grids overlap, rules for both genres apply, and this area constitutes a 4x4 region for any grid with regions.

(Clarification: the rules listed below only apply to that 10x10 grid. For example, a cave clue does not see unshaded cells beyond the cave grid’s border. And, there can be a fourth shaded cell outside the aqre border connected to a line of three shaded cells inside the aqre grid.)

The thirteen grids are as follows:

Heyawake
- Shaded cells are not horizontally nor vertically adjacent.
- A number indicates the amount of shaded cells in that region.
- Unshaded cells form an orthogonally connected area.
- There cannot be a horizontal or vertical line of unshaded cells that goes through two or more region borders.
Aqre
- A number indicates the amount of shaded cells in that region.
- Shaded cells form an orthogonally connected area.
- There cannot be a horizontal or vertical line of more than three consecutive shaded or unshaded cells.
LITS
- Every region contains four shaded cells that are orthogonally connected (i.e. tetrominoes).
- Shaded cells form an orthogonally connected area.
- Shaded cells cannot form a 2x2 square.
- Two identical tetrominoes, including rotations and reflections, cannot share an edge.
Cave
- Shaded cells are orthogonally connected to the edge of the grid.
- A number is unshaded and indicates how many unshaded cells can be seen in a straight line vertically or horizontally, including itself.
- Unshaded cells form an orthogonally connected area.
Canal
- A number is unshaded and indicates how many total cells are shaded in continuous lines starting from the cell. These lines are in the four cardinal directions (up, down, left, right).
- Shaded cells form an orthogonally connected area.
- Shaded cells cannot form a 2x2 square.
Cocktail
- Each region contains at most one block (i.e. an orthogonally connected group of shaded cells).
- A number indicates the amount of shaded cells in that region.
- Shaded cells cannot form a 2x2 square.
- Shaded cells cannot be adjacent across region borders.
- Blocks form a diagonally contiguous area.
Chocona
- Each block (i.e. an orthogonally connected group of shaded cells) must be a filled rectangle or square.
- A number indicates the amount of shaded cells in that region.
Nori Nori
- Each shaded cell is orthogonally adjacent to exactly one other shaded cell.
- Each region contains exactly two shaded cells.
Nurikabe
- A number is unshaded and indicates how unshaded cells are part of that group (i.e. an orthogonally connected group of unshaded cells). Each group contains exactly one number.
- Shaded cells form an orthogonally connected area.
- Shaded cells cannot form a 2x2 square.
Chocolate Banana
- An orthogonally connected group of shaded cells must be a filled rectangle or square.
- An orthogonally connected group of unshaded cells must not be a filled rectangle or square.
- A number indicates the size of the (shaded or unshaded) group that contains it. A group can contain zero, one, or more than one number.
Shimaguni
- Each region contains exactly one block (i.e. an orthogonally connected group of shaded cells).
- A number indicates the amount of shaded cells in that region.
- Shaded cells cannot be adjacent across region borders.
- Two regions sharing a border must have blocks of different sizes.
Stostone
- Each region contains exactly one block (i.e. an orthogonally connected group of shaded cells).
- A number indicates the amount of shaded cells in that region.
- Shaded cells cannot be adjacent across region borders.
- If all of the blocks were to fall down, they must completely fill the bottom half of the grid.
Hinge
- Each block (i.e. an orthogonally connected group of shaded cells) is cut exactly once by a single straight segment of region borders, across which it must have reflectional symmetry.
- A number indicates the amount of shaded cells in that region.

Lösungscode: The number of shaded cells in the bottom row of the Heyawake grid, then Aqre, then LITS, Cave, etc. (13 numbers)

Excellent! Each partial grid is fun to solve, and the interaction in overlapping parts is just lovely!

Wow, such a beautiful puzzle and consistently enjoyable long solve!

Incredible! Solved with Isaiah (no way I could've done this on my own). I met only 5 of the genres before in GAPP, and didn't solve any in a while. Thank you for setting this beauty!

when do we get a hard one?

Sublime first half. Extremely weird (but still enjoyable!) second half. Thank you so much for this marathon, it was a ton of fun! :)

It is very hard to find the wrong part when I solved the grid but penpa had no response. I think the intersection of Heyawake and Cave is very interesting. I always forgot the restriction on unshaded cells of aqre, cost me some time. A good puzzle!

Third Generalized n×n Puzzle solved, where n is greater than 20.

Epic ! From the individual puzzles to the neat interactions in the 4x4 areas, a very entertaining fresque of shading genres. Thanks :)

Excellent puzzle! Thank you! I had never solved 10 of the 13 genres present in this puzzle, but the difficulty felt just right all the way through. It took me a little over 4 hours, so surprisingly manageable relative to the size of the puzzle and my unfamiliarity with many of the rules.

I was planning to leave a comment saying "my favourite grid was...", but I loved all of them! (That being said, if I really have to choose, my favourites were probably the overlaps of canal and cave grids with their neighbouring grids).

Wow that was hard, but very worth every second of solve time. Well done on this creation mathpesto!

Wauw, this was incredible! A superb construction and an amazing solve.
