Twilight Myopia

Like my Projective Plane Amoeba, this is another puzzle I made for a contest in a Discord server I’m in. The theme this time round was to create a ‘twilight’ variant of an existing genre, i.e., a variant where ‘shaded’ clues are to be interpreted differently (usually the opposite way) from ‘unshaded’ clues. I use scare quotes there because the definition of ‘shading’ was intentionally loose so as to allow for genres other than pure shading genres to be featured.

Accordingly, I chose to make a Twilight Myopia; I’ve already made several Myopias and Hyperopias, after all, so combining the two of them into a twilight hybrid seemed a very natural choice. Like my Amoeba, this puzzle ended up solidly in the middle of the final leaderboard, which is about what I expected; it’s not a very smooth puzzle, but it does at least have a couple of interesting moments, so I’m decently happy with it. Enjoy!

Ruleset

  • Draw a single non-intersecting loop along the edges of some cells.
  • A clue inside the loop is a Myopia clue: it points towards all cardinal directions whose closest visible lines are the closest to the clue.
  • A clue outside the loop is a Hyperopia clue: it points towards all cardinal directions whose closest visible lines are the farthest from the clue.
  • A direction without a visible line is treated as having the closest visible line at infinity, and is therefore always the farthest.

    Good morning, Mr Ben Woodley

    I use the sites of Otto Janko ( http://www.janko.at) and ( puzsq. logicpuzzle.app) to play with the great quantity and variety of puzzles they supply ( tons ).
    Lately I uncover Myopia Puzzle and I liked it very much but there are few ones.
    Can you tell me how and where I find many of those puzzles?
    Thank you very much for your kindness and your help.

    Best regards

      Hello José – so sorry I missed your comment previously, it got caught in the spam filter! Unfortunately, Myopia still doesn’t seem to be a very popular genre, so there aren’t many puzzles available – the only other source I can think of that you didn’t mention is Pedro’s site, https://pedros.works/kudamono/pages/myopia. I would also perhaps recommend the videogame Islands of Insight, as it has some fantastic Myopia puzzles – it’s probably not worth buying if you’re only interested in Myopia, but I think it’s an excellent game. Hopefully this helps – if you find any better sources of these puzzles, please do let me know, as I’m as eager to see them as you are!
