Lovely puzzle. Got this one in 02:25:11 which is rather good for me. I loved the opening, where I quickly concluded "ah, I see, because of the square constraint unlike normal Dutch whispers, a 5 cannot be on an orange line in this puzzle" which placed my first digit, only to reveal through the fog that it had been placed onto an orange line, forcing me to immediately revise my incorrect deduction :)
Mark did a Simon by using a complicated detour in box 5 instead of the easy route of just seeing that 7&9 can not be on black dots and thus must be on the orange line
Around 16 minutes in, I placed the 36 by a more direct route. There was a 1 or 2 on the top edge of the orange square in box 6, and a 1 or 2 in the bottom edge of the orange square in box 5, so what was penciled as being possibly 126 (r5c7) was actually a naked 6. (You didn't have to speculate on the 3 in r5 box 3 to see that if you put a 1 or 2 in r5c7 then you wouldn't be able fill both of the orange squares.)
16:09 - here's how I found it: r5c4/5 was going to have at 1 or a 2 (dutch whispers logic) and r5c8/9 was also going to have the other of 1 or 2. It was a floating 1/2 pair meaning r5c7 could not be a 1 or a 2, leaving a naked 6.
Wow this was a lovely puzzle! finished in 22:06 so i beat Mark's time, but i did make a brainfart error on going 1515 on a square where 1591 was an option i forgot about. I found out i got a mistake later but could immediately solve it by switching the 5 into a 9, which probably saved me a few minutes. Mark you wheren't the usual champ on scanning today (especially around box 3 you missed a lot of fast and easy deduction looking down for quite a while), but it was all logic (unlike myself) so hats off for the solve and video and thank you to James Kopp for introducing these Dutch squares to me (us all??) in this lovely set up!
Was able to finish this in just 24:03 (conflict checker off) after several glasses of wine, whoo! 😄 Really wonderful puzzle, many thanks to James for it!
31:40 for my time. Some interesting logic in there with simple rules. This is nice. Fog sudokus have the merit of never letting us completely stuck, which feels rather neat.
Don't give up, though -- it took me a few years of watching lots of CTC and playing along with them, pausing and trying a few step of logic myself and then unpausing when I would get stuck to learn how they got past that spot...I still cannot do all of the ones these two geniuses can do :) -- but I can do more than I used to. It's a journey that is worth taking.
I finished in 36:16 minutes. This was a really nice approachable Fog of War Sudoku. There was a point in the puzzle in box 6 where I stopped myself from pencil marking it as I thought it wasn't necessary to connect the orange lines in a square. Then, I reread the rules as I usually do when I get stuck and say plain as day the rules about all clues being squares. How daft of me. I need to get better at reading the rules. I really liked the simplicity of that ruleset. It made it really fun in the fog of war. Overall, it was a nice and fun jaunt. Great Puzzle!
16:00 - you said you didn't know how that happened, there's a hidden quad in row 5. with 1268 - one of columns 4 or 5 is either a 1 or a 2, which when combined with the numbers in r5c7-9, gives you a 1268 quad, making r5c6 a 3.
Funny, once Mark got the 5 in the center box I expected him to find the obvious about the orange square in the center box... those take up four cells, the two black dots and the 5 take up the other remaining cells in the center box. You cannot put the 7 and 9 on the black dots, so they must go on to the orange line. The orange can only include two high cells, so the black dots must take the other two making them 48- and 36-pairs.
I am a bit intimidated by James Kopp puzzles, but this one seemed possibly within my ability! I will put it on my list, though I am sure I will need to refer to your video, Mark, in order to get through a couple of places I can see will be sticky for me.
At 8 minutes: neither 7 nor 9 can go on a black dot, therefore, in box 5, 7 and 9 MUST go on the orange square, therefore the black dots must contain the 6 & 8. So the black fots are 3-6 and 4-8 and the square is 1-7-2-9 ( in some order )
I got stuck right about where Mark does at 14:05 (I was much slower than 14:05, lol) when I discovered a naked single at r5c7...I'm very proud of myself for finding that - It was hard to see.
46:37 pretty consistent difficulty throughout the puzzle edit: never mind, I realized while watching the video that I placed 5 in r7c7 as soon as it was revealed, which I wasn't allowed to do, didn't solve it after all but had some fun anyway
I thought for just a sec that there was a deadly pair in the row 6 and 7 there which couldn’t be resolved without me looking at giant 2 next to a 37 pencil look on a whisper🤦🏽♂️🤦🏽♂️ BTW fun filled solve, did it in 20 mins 32 secs
Why would Mark pencil a 7 in R2C2 when he already has it marked in R1 in that box? Does he not pay attention at all to what the heck he's doing? It seems to me that his sudoku got so much worse those last couple of years...
@@Eggo5522 You comment is... I don't know. Are you perhaps on some perception-altering medication? Is that why you missed the point of my comment entirely? What does r1c2, or even r1c3, have to do with anything? I commented on how Mark considered 7 as an option for r2c2 even though he DID know that 7 had to be in R1 in box 1 (because of the x-wing on 7s in boxes 2-3), without paying any attention to his own pencil marks. And I got rather mightily annoyed at that point, because he's a seasoned pro, not a 10yo noob.
@@RichSmith77 True, but that was always Simon's thing. Mark was always good at reading the grid and his pencil marking was neat and helpful. Simon is brilliant at dismantling the logic behind the puzzle but as a solver he is and always was very chaotic. But nowadays - and I've seen it for many many months now - Mark's solving is just like Simon's: messy and careless, with lots of erratic jumping around the grid.

Excellent time. Any finish is a great finish.
Liked how the challenge of the puzzle continued right up to the end.

Me too. My favorite bit of logic in the puzzle.
Yes, there's a floating 1-2 pair spanning the two line segments in row 5 👍🏻
Me too...
Thank you! I'm not sure how I missed that, but I did.
@@abcrtzyn I also loved it, it is a miracle that I noticed it with how much debt I have in the sleep department.

39 minutes, I'm happy with that, thank you for featuring
I almost never watch after I've solved, but I'm glad I did and saw that this stymied everyone as much as myself at various points.

Great puzzle with an approachable start that slowly got a bit harder, love it.
25:14 ... I'm always up for solving fog sudokus, even if I don't always actually finish a solve
Nice puzzle!
Tried it. Got part way through and stalled. Too tough for me. Watched Mark solve it. Brilliant as always. Thanks.

30:53 And very happy with that time! Good fun!
34:02 - I'm usually not great with fog puzzles, this was one of the few I was actually able to get through.
48:35@#7185. It was a bit tough in places, but cleverly arranged. I liked the way the restrictions played off each other.
A great puzzle and a great solve.
13:20, yay fog puzzle! I especially like how I was working on boxes 5,8,9, then somehow got the 6 in r6c1 clearing fog in the middle of nowhere.
forgot to do sudoku 5 times in this one. can't believe i'm saying is but i'm starting to understand simon
Wonderful puzzle.
Interesting puzzle! I didn't have to be stuck for very long.

22:19 for me. Nice fog puzzle.
18:35 lovely puzzle
Nice and simple. 23:46
46:37 pretty consistent difficulty throughout the puzzle
edit: never mind, I realized while watching the video that I placed 5 in r7c7 as soon as it was revealed, which I wasn't allowed to do, didn't solve it after all but had some fun anyway
85something minutes, I kept staring for eternity until I found that magic 6 clearing next cells.
I thought for just a sec that there was a deadly pair in the row 6 and 7 there which couldn’t be resolved without me looking at giant 2 next to a 37 pencil look on a whisper🤦🏽♂️🤦🏽♂️
BTW fun filled solve, did it in 20 mins 32 secs
Standard sudoku rules imply Extraordinary sudoku rules
23:56 for me. That was nice.
That was a lot of fun! I got hung up in the middle for a bit, but that's part of the challenge, right?
14:09 - good bit of fun :)
25:18 for me with a bit of video help in a 1 or 2 spots
31.13 for me. Got stuck at the 6 too.
16:38 for me, very fun!
12:52 today. should have been better. i got stuck for a while. a sub 10 sudoku.
solved in 18:31 - got stuck for quite a while at the hard parts
00:27:00
36:35 - Not quite as easy as I expected.
31:33 for me
nice puzzle
00:44:54 - No help by video!😊
8:27 for me. Great puzzle!
29:20 for me.

Because until he has resolved r1c3 he cannot rule 7 out of r1c2...
If you are going to be unnecessarily rude at least make sure you are right first.

Both Mark and Simon are pretty good at ignoring corner pencilmarks in boxes from time to time. They both get the job done though.
