Yajilominous
(Published on 16. March 2025, 18:25 by Nell Gwyn)
This is the puzzle I made for round 2 of a competition in the Skunkworks Discord server. I chose Pentominous and Myxo chose Yajilin, and we each made a hybrid of the two genres (of course Myxo's puzzle won, but oh well, mine is fun too!).
RULES:- Yajilin: Shade some cells gray. Gray cells cannot share an edge. Arrows indicate how many shaded cells are in the indicated direction. Clues with two arrows count each direction separately. Some gray cells might not be pointed to by any arrows.
- Draw a single closed non-intersecting loop that moves orthogonally through every cell that is neither shaded gray nor a blue arrow clue.
- Pentominous (sort of): Divide all non-gray cells (including the blue arrow clues) into pentominoes. No two pentominoes with the same shape, including rotations/reflections, share an edge. A letter clue gives the shape of the pentomino it is part of (see the example image). A pentomino may have multiple arrow clues.
- The loop must visit each pentomino exactly once.
Solution code: Row 13. Use "*" for shaded cells, and for all other cells use the letter of the pentomino shape that cell belongs to.

Superb puzzle. This was fun all the way through, kind of a perfect example for a "flowy" puzzle, with great setting that directs you where to look. The highlight though was the great ways the loop restrictions and line geometry forced the exact kind of wonderful logic one would expect pops out of a combination of these two variants. Such a blast! Thank you

In my original rules I forgot to specify that gray cells can't share an edge. Sorry about that.

Extraklasse! Und richtig schwer. Die Konsequenzen von Pentominos ohne Schwarzfelder und nur einmal durchlaufen sind gewaltig, aber man muss da höllisch aufpassen weil es auch noch die Pfeilfelder gibt.

Exactly, both puzzles are great. Personally, I just found this one a little easier.

Very smooth for me. Both puzzles in this matchup were excellent and it was interesting to see subtle differences in how you approached the hybridized ruleset

Really fun puzzle with some surprising logic and a very smooth solve path!
