No. 03 - School Trip #01

Ah- back to school season. How I miss going to school (instead of the permanent study hell I'm stuck in). I, however, doesn't miss the alarm clocks one bit. Speaking of school, here's unusual puzzle type that involves avoiding bad luck --- School Trip.
Rules of Shugaku (School Trip) (Translated from this site):
1. Place numerous 1 by 2 blocks (futons) onto the board (vertically or horizontally). In addition, put a □ (pillow) in one of the squares for each futons. If the futon is placed vertically, the pillow must not be on the upper half (north-facing pillows are considered bad luck).
2. Futons cannot be laid on the circles (pillars).
3. If there's a number in the pillar, it indicates how many pillows are adjacent to its 4 sides.
4. All squares that are not covered with either futons or pillars are considered aisles. Each futon must touch at least one aisle square on one of its sides.
5. All aisles must be connected. The aisles cannot form a 2 by 2 square.

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.
