      Quick fix: change the 2x1 purple piece toughing the corner of the red square to blue, the T-shaped blue piece above it to purple and finally the square itself to blue. You still have two shapes of the same color touching corners, which is not technically a problem but I feel is a tiny bit less elegant. I wonder if there is a way to do it without corners touching - I’m too busy to try it myself. Skylark Murphy’s solution also has touching corners (once you correct the L shape above the square).

    This is brilliant, but I screwed up many many times by forgetting that the numbers outside the grid obviously don't affect the whole row, only the numbers within the killer cages. Ultimately took me just over an hour of focus. Still, though, what a brilliant puzzle set. How she comes up with these things I'll never understand!

    Visiting from the future! OK, actually coming back to see some older videos. This was a great one, but really makes me appreciate that they have reduced the INTENSITY of the colours in the app. These were so bright that they got in the way of seeing the numbers.

    This one took me multiple attempts, mainly because I kept thinking that numbers outside the grid eliminated numbers inside the grid. Once I got over this grave misconception and used stone cold logic, however, the puzzle opened itself for me and gave me one of the most delightful solving experiences ever. Laura, please, please do keep setting more puzzles! I'd definitely purchase a puzzle book from this author!

    This is a very rich puzzle. I was never stumped for a possible next move to make progress, but I had to keep changing strategies, from skyscraper to killer to sudoku. Took a long time!
    And it's tricky, in that you keep thinking that the numbers outside the grid rule out numbers in the rows and columns but they don't.

    The colors make the grid look very busy and the numbers very hard to make out. I would recommend to increase the brightness and decrease the saturation of the colors used to shade the grid. Besides that, of course, fantastic puzzling as always!

  • @richardfarrer5616
    @richardfarrer5616 5 лет назад +4

    One thing I noticed while solving this - a skyscraper clue and the first number next to it can never add up to more than 10. For example, if the first number in the main grid is 6 then the longest sequence is 6-7-8-9 so the skyscraper clue would be 4. Based on that, both of the 20 boxes at the edge of the grid decompose into two 10s instead. Still took me over an hour to solve though :-(

    Loved this puzzle and had a blast solving it. I do think that because there is so much information, but it is so hard to decipher, that every person's solve is probably quite different on this one. I ended up noticing a lot of 12345 quintuples because a lot of the cages, which is definitely something you don't end up with too often in normal Sudoku

    A fun puzzle, very challenging for me. Took me over 3 hours. I'm not very good yet at Killer Sudoku and the numbers outside the grid kept causing me to keep making scanning and notation mistakes. I wasted the first hour because after all the Sandwich Sudoku I've been doing in the App noted a 15 cage incorrectly. Thanks for the puzzle as always guys!

  • @57thorns
    @57thorns 5 лет назад +1

    I messed this up twice, ending up with having to watch the video while solving it. But there is one simple rule that would have been useful on row 2:
    Whenever a skyscraper number is 2, you either have an 8 next to it or a 9 one step in. The 9 in row 2 could have been solved much earlier.

  • @dudbike

    As others have said mixing the numbers outside the box makes it error prone. Maybe next time a thicker outside box would be better.

    I'm not sure how, but I wound up reversing the 573 / 357 in the last three main puzzle columns, which made the skyscraper break. I wonder if the logic I used was sound, and only broke because of the skyscraper constraint? Doesn't seem like it should be. I probably just made a mistake.

      Come on, they gotta get watch time. At that point there's no reason to watch the video at all so it hurts their hustle.
      I know when I try the puzzle and get it done easily enough to where I don't think I'm gonna learn much from the video, I'll at least let it play all the way through while I'm doing something else. Most people won't know or won't care, though. I ain't got money for patreon and all that, but I do what I can to support good channels like this.

      Maybe a white outline instead? It would still look the same in white background and would probably look better with colored background.
      Either that or a bit softer colors so they are more "pleasant to watch".

    I want to enjoy this video but unfortunately the choice of colours is making it physically impossible for me to follow anything since I can barely see that there are numbers in any given square let alone read the numbers. That purple(?) that is being used for the notes is just atrocious for the colourblind and, unfortunately, makes the video quite unwatchable for me

    • @Tehom1
      @Tehom1 5 лет назад +1

    • @TheWhite2086
      @TheWhite2086 5 лет назад +1

      @@Tehom1 Yea, on the site itself I can make the colours work but unfortunately that doesn't help in watching the video when any notes that are place in the purple boxes are invisible and the ones in the red and orange ones are visible but unreadable (and the blue boxes aren't easy to read but at least not physically impossible). It's the first time I've seen a video on this chanel where I physically can't see more than half of what is happening.
      It is definitely something to do with this puzzle specifically, if I go to a puzzle from a different video and set the colours of the sqares to 5, 6 or 7 then I can see notes put in the squares but on this one those same colours make them invisible or unreadable
