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.

Nurikabe (warning : hard, may be unfair)

Statue Park 🗿 🏞️

    We're taking a stroll through Statue Park. This genre is classified as object placement and shading, and more hybrids of this type exist. The tags system I'm using will then list them in both categories. It's a fun genre, and the logic behind it is plentiful. Here are the rules :

Place every shape from the bank into the grid. Shapes can be rotated or mirrored.

1. All shapes must be used exactly once. There cannot be shapes in the grid that aren't present in the bank.

2. Two shapes cannot be orthogonally adjacent.

3. Black circles must overlap a shape, while white circles must not overlap a shape.

4. All cells not used by shapes (white cells) must be connected.

     To clarify, if a shape appears N times in the bank, it must be used exactly N times, and shapes are placed as shaded groups of cells. So take the time to study the bank before jumping on the puzzle. For your convenience, most puzzles use a set of tetrominos (single ou double), or all 12 pentominos. It is best to remember these shapes and practice with them, as the puzzles will need the use of properties of each set to be solved. And I cannot stress this enough, the connectivity of white cells is your bread and butter for these puzzles.
