    When the XY is shown to me, it becomes obvious. However, the odd of me finding one in the wild are slim to none!

      Согласен на 100%! Быстрее банальным перебором решить судоку, чем искать (и не найти) необходимые пары. 😏

    Excellent video - I’ve watched this video three times over the past week and today I finally found and solved an xy wing. It feels great to have spotted an xy wing and worked out the logic. I have been struggling with the xy concept for sometime and this video make total sense to me. Thank you.

    Not following very well, but definitely do a spot check now with the XY and it helps identifies the single # that goes in the box. I use probabilities which work only 90% of the time, though

    For example 1 - I don't see how this is a y-wing. Both of the wing cells have only two candidates, yes, but BOTH candidates in each of the wing cells are also in the pivot cell. That is until at 1:05 two candidates in the pivot cell magically disappear to make the pattern fit the definition. How did you know which of the 4 original candidates in the pivot cell to eliminate?

    I copied this puzzle a couple of months ago, stowed it away, and tried to solve it on my own this morning. I found a different y wing: cells 41, 63 (pivot) and 69 which combined eliminate the 469 in cell 61, leaving a 3 for that cell. Maybe technically it's not a y wing but I think it works.

    At 1:05 a bunch of numbers magically disappear, (crucially, the 28 in row 2 column 6). Why is this? Is that part of the Y wing 'magic' or was that done by some other logic that I can't follow?

    It looks to me that any of the three cells can be considered pivot cell while the other two wings, right?

  • @betmenizorahovice4843
    @betmenizorahovice4843 Рік тому

    if thats xy wing there is another one with the 79 in the middle box aka box 5, one wing is in box 2 contains 47 and the other wing is in the box 4 and contains 49, either way both box 2 and 4 could have number 4 but that solves nothing
    i wonder is it xy wing at all or it is but its just unusable xy wing
    someone ?

  • @stuarthine1144

    This solution violates the multiple solutions rule. When you lay the 8 you end up with 4 intersecting cells with the candidates 2/8... Unless there's an error somewhere else. Cells in question are A4, A9, H4 and H9

    0:33 Instead of relying on Google first-page response, in the future how about curating/picking a clearer definition? Because Google's was awful. "unit".... okayyyy, what a uselessly broad term. Ugh. And how does it define "first"? It doesn't. If you're going to try to teach you have to use well-thought out materials that are appropriate to beginners. I think your videos have merit, but teaching is a skill that requires effort to think llike someone who knows little/nothing of the topic you are trying to teach. At 1:02 we see 6,B lose two candidates without explanation. You never explain HOW you spot an X/Y wing, they're just magically green now. Nor do you explain why that is the "pivot" cell (we have to guess it's related to intersection). Again, I think your vids have merit, but you need to proceed from the standpoint that the viewer does not know what you know.

    1:53 Seriously? SERIOUSLY? That's your explanation for the naming? Seriously thinking about unsubscribing.
