Friday Puzzles #69

So this week I’ve decided to keep playing with the alternative presentation of Yajilin. My argument at this stage is that this really isn’t a stand-alone Yajilin variant, and to reply rather lately to the comment MellowMelon made on the last post that yes, I agree that in general it isn’t too hard in filling up the grid with “useless” clues. With this presentation, I could indeed have gone through that process this week, but there are two main reasons why I’m serving you up the following.

Firstly I couldn’t be bothered. What can I say, maybe I’m lazy, maybe I just need the right motivation. But secondly, I think the shaded squares add a certain something to the aesthetic appeal of the puzzle over, let’s face it, is otherwise a rather barren looking grid.

Certainly, this is a different sort of solving experience going on here, working out the claustrophobic implications of the narrow passage ways than you’d see in your average Yajilin puzzle, but I think it must be reiterated that it’s an easy job to put these back into “standard” presentation.

But you’re probably getting bored reading all that, and would much prefer some puzzles to solve. Enjoy!

#084 Yajilin – rated medium

[My apologies for inconsistent and unsolvable early versions of #084. For the record, the top left clue went from being unmarked, to being a 0, and finally to its correct status as a 2:)]

#085 Yajilin – rated medium
