    Thanks for that feature! Scojo challenged some setters to create puzzles with doublers and yin yang a few weeks ago and this was my contribution. There were lots of interesting puzzles among them. Of course I couldn't help myself and added fog to the mix :D

    at 51:55 "Let's have a look at the shading" Simon shades the colors backwards for r67c3 while hypotheticing a 1 in r6c2. However it still breaks because you end up with a shaded 2 in r6c2 and an un-shaded 1 and 3 on the arrow (r7c2 and r8c3) -- meaning unshaded cells all the way around r8c2 which isolated the shaded cell

      @jasond4084 Месяц назад +5

      That whole sequence seemed painfully obvious. Even before the color blunder. After 4 was determined to be in b7 c1, 2 could never be placed in r6 c2 as a single or a double. Sometimes I wish I could whisper through time and space into Simon’s ear but only yelling works. 😂😂😂

    I finished in 58:08 minutes. This was one of the most incredible fog of wars I have done. The doubler and Yin Yang rules work really well in fog of war. I was even able to get the border before I put any digit in, which felt strange but cool. It was so fun to keep getting 9 as a doubler value, especially the arrow clue in the top left. As fun as those were, they pale in comparison to my favorite part. I felt as if the whole construction led to this moment, which is insane to think it is on purpose. It is getting a 12 pair in r6c2&3. Figuring out that the 1 was doubled with an unshaded 2 was easy. The insane part comes from always proving that a 1 exists on the 2 clue and exactly in row 7. This allows a snipe on the digit in r7c7, which feels like it comes out of nowhere. The way I saw it was asking if 2 could be a double 1 pair. This creates a diagonal shape of unshaded, locking in the shaded cell in r8c2. That was already amazing to see. This meant both 12 were doubled. Trying the same thing again with the doubled 2 on the inside leads to the same problem if you diagonal it again. This forces it to head right where a 1 is always in row 7. That was incredibly construction and one of the sickest things I have seen. This puzzle has to be one of my favorites. Great Puzzle!

    • @lyraparry3321
      @lyraparry3321 Месяц назад

      That's incredible!! I got the r7c7 single after deducing that the 2 couldn't be in c2 for exactly the diagonal trapping reason you just described, which allowed me to place it in c3 and actually see the arrow. XD I can't believe I missed the fact that of course moving the diagonal trap over by a block wouldn't stop it from trapping the shaded cell! I think my favourite bit in my solve was the deduction of the 8 in box 6. I'd deduced r7c7, and then I worked out that I couldn't use 7 on the end of the arrow because that would put an impossible 8 in the circle, which left me a 345 triple in r5c7, r6c7, r6c8. That left the last digit remaining to be placed in the box as 8, which immediately disambiguated the 348/58 arrow in boxes 5/8. I loved that so much.

    29:12 for me, love these Fog sudokus. I tend to get lost in complex puzzles with even finding where to start looking for the break-in, whereas fog sudokus are more or less just solving a bunch of small break-ins, knowing almost exactly where they are. I think that's what makes these so satisfying.

  • @stephenmarseille5425
    @stephenmarseille5425 Месяц назад +18

    Simon, at 52:00 you've miscolored your hypothetical (the one at r6c3 should be orange, the 2 below it should be blue), this undoes your checkerboard logic, which means you got lucky at 53:00 with the reveal of the 2 in r7c2. You likely would have resolved it anyway as the only way to make it work would have left the orange at r8c2 stranded, but still.

  • @olivier2553
    @olivier2553 Месяц назад +2

    I can't believe I made it. 46:01 for the sudoku, a bit longer to finish the shading. And I think I only made 3 errors (putting a digit that did not reveal the expected fog, Once in R3C1 and twice in R7C5) and forgot about the change of colour on the perimeter. I thought I was at a blockage, that I would never finish the puzzle by myself and started watching Simon. I was at the exact same stage when Simon mentioned about the colour of the perimeter and I decided to give it another try. Thanks Simon gdc and Sven.

    56:52 for me. After a quick start I got stuck half-way for quite a long time (with the circled 12 pair in box 4), but eventually I found the correct logical path without help from the video. Very satisfying! Many thanks, gdc :-)
    It is so enjoyable to see Simon follow almost the same path I used, also spending a lot of time on pencilmarking the 3-4-5 arrow in the middle, before the breakthrough with the circles 12 pair occurs...

    I'm sorry, the sudoku solving hasn't even started but I must comment: "I used to buy buckets of cookies" might be my personal favourite of all the things I've ever heard on this channel, especially since it was presented in such a positive light. I'm turning 35 in a few weeks time and it is becoming more evident by the day how ruthless time really is. If you are in your twenties, please, do eat buckets of cookies. The time to do so and get away with it will be over sooner than you'd ever guess.

    • @RockyInSea74
      @RockyInSea74 Месяц назад +1

      I think I got it. If R6C3 is the doubled 1, then there is no way to make R6C2 a 2 without doubling it. So, R6C2 is doubled if it is the 1 or the 2.
      Now if it is double 2, then you can't do double 1 below it and add 2, because the 2 will already be used by the 1 arrow next to it. So the digit right below it would have to be undoubled. It can't be a 4 and if you do a 1/3 pair undoubled, it would have to surround the doubled digit in R8C2 with undoubled squares. So, there is no way to get R6C2 to be a doubled 2 and is thus a doubled 1 with the 2 below.

    • @maspleben
      @maspleben Месяц назад +1

      Yes I agree with you Simon got lost in his logic there and we did not get a proper answer on why it could only be 2 in the left circle. I think he should revisit that logic. Because I got lucky too I have to say, but this is the only thing that can move the solving forward at that point, by revealing the longer arrow for the right circle. So it must be 2 in the left circle, but the logic of Simon was not satisfying.

    • @gdc42
      @gdc42 Месяц назад +2

      ​@@dmb-zw8nn yes, that is the point. I put that arrow there intentionally to look like it's going to connect and then end up as a short stubby one :D. I think Simon saw that this breaks but just did not verbalize it.

    • @ingiford175
      @ingiford175 Месяц назад +1

  • @craigyoung8008
    @craigyoung8008 Месяц назад

    I find it particularly amusing 22:05 that despite Simon diligently explaining the yin-yang techniques a few minutes earlier, he calculates whether r4c9 can be doubled.
    Instead of simply filling the perimeter from r3c9 to r1c6 in blue.
    And then he still goes on to solve the entire puzzle quicker than me. 😖

    I think the deduction at 31:22 is wrong because if R1C1 and R3C1 are a 12 pair, and R4C2 is a 1, you can make the circle in R4C3 a doubled 8 and the arrow (with the doubled 6) adds up to 16
    If I am wrong someone please let me know, but as of now I don’t fully understand how Simon’s way is the only way

    • @gdc42
      @gdc42 Месяц назад +4

    "This can't be a three four to make seven." No. It's a three four make 10. :D
    I really like the start. Forcing large digits to clear a third of the fog right away is different than most Fog puzzles approach of creeping crossing the grid. I'm a little annoyed with myself. For 20 minutes I was convinced the square R6 C2 to R7 C3 was going to be a pair of twos and a pair of doubled ones. A deadly pattern resolved by the shading. Simon immediately noticed that would make a checkerboard. Doh!

    • @HunterJE
      @HunterJE Месяц назад +3

      That would need at least an 18 value (note the 1 and 2 already used in row 4), but 9 is ruled out of that circle by sudoku

      Because the minimum is r1c1 = 2, r2c2= 12, r3c1= 1, r4c2 = 3 totaling 18, and there's already a 9 in column 3 so it can't be a doubled 9.

    • @pairot01

      because the line would be too long, the 9 in the row has already been used!

    Finished it but made a few wrong assumptions. Only finished it because the fog didn't disappear and had to think about why it was wrong. I hadn't utilised all possible ways the arrow could go because of the double value.

    Starting around 51:55, isn't he using a nonsense coloring to disprove that R6C3 is a 1? Shouldn't R6C3 be orange (doubled) and R7C3 blue (natural) with a 1-element arrow? Then R6C2 can be an orange (doubled) 2 and R7C2 a blue (natural) 1, with the arrow picking up a natural 3 in R7C3?
    The actual reason it can't is that this creates an isolated shaded cell in R8C2.

  • @ewenfraser883
    @ewenfraser883 Месяц назад

    Is there any reason why the arrow in box 3 can’t turn 90 degrees and go to r4c8 instead of r4c9? In other words do arrows only turn at cell centers? If so that must be specifically stated in the rules

    • @RichSmith77
      @RichSmith77 Месяц назад +1

      I guess it's an unstated rule that arrow line segments go in straight lines between cell centres. Maybe you're right, that ought to be stated, but it never is. This could be said about many other puzzles too. This one follows the established convention.

      It's a pack that you purchase from within the standard CtC app, if you update that app to the latest version. (They confusingly refer to it as a new app. It isn't.)

    Something weird happened with this one. I solved without help in less than 24 minutes. It all flowed pretty obviously. Everything seemed pretty forced. I'm not sure I've ever finished one faster than Simon before, let alone this much faster. Did Simon miss something obvious and strange? Maybe a lack of pencil-marking made something more difficult and "missable?" Perplexed... I'll have to watch the video to see...
    PS I've concluded that it's just all the extra explanation that Simon does.

    Maybe I missed it- why can't the arrow in r1/c1, r2/c2, r3/c1 have it's bulb in r4c3 at around 31 minutes?
    I mean, you can pretty quickly figure out r3/c1 has to be 1, which shows it's not, but I think he just made a lucky guess?
