    The snake segments could have been marked “?”. It also could have been solved with the head marked 32 removed and the 44 updated appropriately. I’m not sure about removing the 44.

      Thanks for the puzzle, and to “y” for an interesting second solving experience. It’s quite interesting to solve without the snake head givens, with somewhat more involved logic. It turns out that the 44 needs to be placed for uniqueness, since otherwise the loop could pass just to the right of the 44.

      • Rob Says:

        To make the puzzle headless without changing too much else, you can replace the “5” in row 4, column 6 by a “4”.

        Well I solved it without using the head givens, I just never bothered. I still can’t find the alternative solution, though…

      • y Says:

        Rob was referring to not having the head placed. I suspect you are referring to not counting the snake length. Those are different problems.

    • Bryce Herdt Says:

      I checked removing the 44, and if the length is unknown, there is only one ambiguity where the path bumps to the right of the square 44 was. So the length would be necessary there, but I should point out that the path would be without direction.

      • MellowMelon Says:

        I should note that I never intended direction to have to be a part of the solution. If a future puzzle has all snakes of the same length, that puzzle would have to have two ways of drawing the snakes themselves, and I’d be okay with that. It’s just about which squares are in the snake loop and which aren’t.

    Very enjoyable puzzle. developed some new short cuts this time around. I enjoy these more than standard Tapas. Keep em coming.
