    Thank you so much, Simon! It’s always a pleasure to be featured on the channel. I’m glad you enjoyed the puzzle, and as you mentioned at the end, it felt natural to combine the constraints, which is exactly why I designed it this way! You followed most of the intended steps, but what I’m particularly appreciative of is how you found the intended logic in Box 7 on the average line. A big thank you to everyone who recommended it, and a special thanks to Sirxemic, the developer of SudokuMaker, for solver support of Average lines. Hopefully next time, you’ll have a 3 in the corner to sing the song! :)

    I finished in 58:26 minutes. This was a really fun puzzle to figure out. I very much enjoyed spotting the 5's that had to go in immediately, which created a funny scenario that effectively added an additional line in each of box 1 and 9. I think my favorite part was seeing that the vertical gray lines on the right side had to both be the same and that they had to show up in the yellow line in column 9 of box 3. This forced it to a 46, which was an amazing deduction. I very much enjoyed this one. Great Puzzle!

  • @RealCadde
    @RealCadde Місяць тому

    13:00 I think you are missing/skipping one interesting bit about the ten lines in box 9.
    The ten line in box 6 sees three of those lines. Therefore, that line is not the same as any of the three in columns 8 and 9 of box 9.
    You now have identical dominoes (R8C7-R9C7) and (R4C8-R5C8)
    And you then might wonder where those digits go in box 3... Maybe.
    If they went on the average line, the average of that line would be 5, which it can't be. So one of those digits adding to 10 will go in the circle.
    And one will go on the average line.
    So the total sum of the average line is greater than 10. And it is divisible by 3. Such as 12, 15, 18, 21 and 24.
    But clearly it can't be 24 because it would have [789] on it and any two of those digits would add to way more than 10. Fifteen to be precise.
    What about 21? [678] would make 21 but again, you don't have digits capable of summing to 10. And not even [579] or [489] works.
    Ok, 18 then? Is it [567]? No, can't make 10. [468] does work and so does [378], [198] etc etc, at least until you consider what the circle can be.
    Anyways, the circle is from [46] (5 is not available) because 3 would be too low implying 9 can hold 10 in it. And 7 is too high because you can't make any two digits sum to 10, while also making three digits sum to 21. You'd need an eleven digit.
    So the line sums to 12 or 18.
    Where 18 would be exactly [468] with 6 in the circle.
    And 12 would be [246] with 4 in the circle.
    And now we know what the identical dominoes in boxes 3, 6 and 9 are made up of. [46] pairs.
    And we also know that the yellow line in column 9 inside box 3 is made up of even digits.
    Thus, you can only have ONE more even digit in column 9.
    And we know ONE of the dominoes in box 9 will be made up of [28] and they are both even, right? So all of column 9 in box 6 is made up of odd digits.
    And R6C8 is therefore also odd, so it can be averaged to an integer.
    We have 4 odd digits in box 6 so far. And the white dot needs two odd digits and two even digits. So R4C7 is an even digit, else the white dot fails.

    32:00 You should instead consider what it means that [28] went in R3C1-R3C2 for the blue dominoes.
    Blue is not green and it's not [28] so blue is odd.
    Is that useful? Not on its own.
    But it means that the domino R7C8-R7C9 is odd.
    Because otherwise, there would be two odd dominos looking at blue, making blue impossible.
    And in fact, that domino R7C8-R7C9 is blue.
    And to be frank, there are plenty of odds/evens clues in this puzzle so far. I haven't solved it myself but i saw it as soon as i got the [46] domino from box 3's logic.
    You have 3 odd digits in row 6.
    What digits can go on the grey line in box 5 to make ten?
    No idea, except i know there will be two odd digits and one even. Because [246] adds to 12, not ten.
    So R6C1 to R6C3 are all even digits. And thus the diagonal domino is an even digited domino.
    And just to be extra clear about the grey line in box 5. Whatever the even digit is, it is a 2 or 4. If it were 6 then there would be a [13] pair with it and make R6C9 invalid. And obviously, 8 is out of the question.
    This means that 6 will go in box 4, row 6. And so it goes on row 4 inside box 5.
    EDIT: 35:12 And if you knew blue was odd at this point, you'd know the 4 doesn't go on blue.
    This makes the R2C1-R2C2 domino green [46].
    And you get a few digits placed by sudoku.
    But even without knowing blue is odd, you could deduce that 4 doesn't go in R2C3 because blue is not green. Green which is the [46] domino.

    • @RealCadde
      @RealCadde Місяць тому

      38:58 What you would have known if you paid more attention to odds and evens is that the average line in box 7 has exactly ONE even digit on it.
      And it's not on the line because and even and an odd makes a non integer average.
      So the circle is an even digit. It's not a 2, duh.
      4 would pair with a 3.
      6 would pair with a 7.
      8 would pair with an 11... I mean, 8 is not possible!
      R9C2 is [46] and R7C2 is [37].
      This makes the diagonal domino a [28] domino.
      And more importantly, because R7C2 can only be a 3 or 7, the blue domino is not a [37] domino! It is a [19] domino.
      This unwinds the whole sudoku i think.

      Yes, you need a language even if you use telepathic transmisson to communicate. Some thoughts are too complex or just too alien to be understood by other species, and must be broken into smaller crystal clear bricks before transmission. Vague or ambiguous thoughts are also translated using standard semantic bricks, and their uncertain nature is preserved by transmitting a chain of possible interpretations.

    I'll tell you, at least, that there have been several playthroughs of the game on UA-cam which do not appear to be being struck down.

    Thank Goodness You're Here! is a bit... concerning at times, even apart from the crude humor. There's a section that I found rather unsettling. I certainly wouldn't recommend it to small kids; it's ESRB M and PEGI 16, and I think it earns at least the PEGI rating. That being said, I think Simon *would* find it hilarious. But it might be better served as a personal channel stream or an off-camera play.
    EDIT: Wait, just remembered there is a sequence where (small, cartoony) adult human genitals are visible onscreen, and I don't know if they have a censor mode. Definitely not the CTC channel vibe.

    Even surgeons are able to turn off their phones for a few hours, yet Simon apparently has to keep his on 24/7 and have it continually pester him.

      @@SpyrosSolda Yes, that's correct. However he's not speaking Greek, he's speaking English. In English it's accepted that the pronunciation is Mu. Furthermore, the letter is specifically being used as the mathematical symbal for mean, which in mathematics and statistics is also pronounced mu.
