No. 20 - Islands #01

 I hate being sick.


Puzzle Link

Rules (From puzz.link):

Shade some cells on the board to form islands.

1. All regions contain exactly one island, which is an orthogonally connected group of shaded cells.

2. A number indicates the size of the island in the region.

3. Shaded cells cannot be adjacent across region borders.

4. Two regions which share a border must have islands of different sizes.

No. 27 - Masyu #03

    So you know how when I'm kinda stressed I use making puzzle as an escape from reality? On an unrelated note here's a big Masyu. Online Play Link Masyu rule (From  Nikoli ): Make a single loop with lines passing through the centers of cells, horizontally or vertically. The loop never crosses itself, branches off, or goes through the same cell twice. Lines must pass through all cells with black or white circles. Lines passing through white circles must pass straight through its cell, and make a right-angled turn in at least one of the cells next to the white circle. Lines passing through black circles must make a right-angled turn in its cell, then it must go straight through the next cell (till the middle of the second cell) on both sides.

No. 28 - Guide Arrow #01

    Haven't touched this site cause of other stuff like "real life" and "distractions". Let's hope I still remember how to make a puzzle. This one is kind of a two-trick pony though. Online Play Link Guide Arrow rule (From puzz.link ): Shade some cells on the board. Shaded cells cannot be horizontally or vertically adjacent. All unshaded cells on the board form an orthogonally connected area. Unshaded cells cannot form a loop. This includes 2x2 squares. Cells with a clue cannot be shaded. An arrow indicates the only direction in which one could begin a path to the star without going through a shaded cell or backtracking. (This genre was invented by Inaba Naoki.)

Me, trying to force intended logic: Yes... ha ha... YES ! Also me, hit with unresolvable uniqueness problem: Screw this I'm out. Online Play Link Rules of Yajilin (from puzz.link ): Shade some cells on the board, and draw a single loop that goes through all remaining cells. 1. The loop cannot branch off or cross itself. 2. Shaded cells cannot be orthogonally adjacent. 3. Cells with numbers or question marks cannot be shaded, and are not part of the loop. 4. A number indicates the amount of shaded cells in the given direction.
