Puzzle 131 ("Medium Nikoli" series, Double Choco)

The next genre in the magazine was Double Chocolate (often shortened to Double Choco).  I'm quite happy with this one.

Puzzle 130 ("Medium Nikoli" series, Yajilin)

A few days ago, I finally finished Pencil Puzzle 2022!  It's a cool collection of puzzles and is worth a purchase.

Each genre in that book starts with a collection of 10x10 puzzles and then moves on to at least one medium-sized puzzle (exactly one in the case of the two Omopa genres Chained Block and Dotchi Loop). I want to construct a "Nikoli-style" medium sized puzzle in each of the genres listed in the book.  Except Numberlink.  I'm not going to hold myself to a 17x17 puzzle there.

First up is Yajilin.  I'm happy with how this one turned out; it's smooth enough, especially with the restrictive clue symmetry.

Puzzle 129 ("Clones", Nurikabe)

Have an easy Nurikabe puzzle.  Getting this theme to work was tricky, and I think the quality of the puzzle went down as a result.  (Note to self in the future.)  However, I'm happy with how smoothly it solves, so here it goes.

Puzzle 128 (Numberlink)

Have another Numberlink puzzle.  I'm not 100% confident this is unique, but I have reason to believe it is.  (Unlike last time, Noq was pretty slow in checking uniqueness for this one, so I couldn't rely on it.)

The way Nikoli pumps out so many Numberlink puzzles is kind of insane.  I have no idea how to create ones that have actual artistry to them nor how to prove uniqueness in a reasonable way. 

EDIT 10/22/22: Proven unique!  Thanks IHNN 😀.

Puzzle 127 ("Pairs", Chained Block)

More Chained Block!  This was a weird one to construct -- I kept thinking the puzzle had multiple solutions only for puzz.link's check feature to save the day.  Hopefully it's smooth!
