A recent PayPal donation requested two types. One of them was this one, and I’m sure he’ll be pleased to hear that the next puzzle pack was already going to be filled with the other.

    Fantastic puzzle. Love the break in, and the number of possible breakins that weren’t.

    These puzzles have a flow thats lot more like hitori.I like the logic in the middle of the solve,though the clue on R9C4 was only there to preserve the symmetry of givens.

      Glad you enjoyed it.

      The number of irrelevant/unneeded clues is to me an overrated metric for judging puzzle quality. Some puzzles are certainly constructed with the intent of forcing a lot from very little, but that’s certainly not the case with all of them, and the only possible time it should be prioritized over the process of the solve is when a specific and worthy aesthetic depends on clue minimality.

      It’s also my opinion that Yajisan Kazusan specifically does better with irrelevant clues. Giving only what’s needed and nothing more can occasionally make the solution path obvious and open doors to meta logic.

        I did one with only relevant clues.You might want to demonstrate your last two statements with an example in one of your upcoming posts.

    Liked the break in as well, around the center I felt like I was doing a Heyawake.. Thanks!

    Enjoyed this one a lot. Agree with the general opinion that the break-in is really nice.

    About the clue relevance discussion above, I don’t really think it matters much either, unless you’re trying to get a specific idea out there. As long as the irrelevant/unnecessary clue doesn’t hinder the intended solution path in any way, I think its fine.

    Very nice puzzle, I thought all of the clues were equally good… 😉
