Thank you, Simon, for another feature! I made this puzzle a year ago because I was enjoying setting puzzles with zipper lines. I wanted to combine Doublers with them, as I saw the potential they had and the interesting logic they could produce. You found the intended path almost perfectly and executed each small piece of logic I designed as part of the solution flawlessly. I must admit, the break-in was a bit challenging, but you spotted and explained it nicely!
The break-in was a piece of genius, both by the setter and the solver. I needed Simon a bit here, after that it unfolded beautifully. Thanks Antiknight, thanks Simon!
I have an almost impossible time starting most of the puzzles he tries, and I usually give up and just watch the video. But once he gets a few digits, I’m always pointing out things he’s missing. What’s fascinating is that it’s becoming obvious that the reason I see simple things he’s missing is because I can’t understand the difficult things he’s seeing, thus I’m not fixating on them. Hopefully, one day I will be half as good at this as him. 🤞😁
Totally! He's over there tracking and untangling complex branching chains of logic in his mind, while I'm over here scanning rows and columns for sudoku. 😅
@1:10:44, no, r3c1 not being 3 means that can't be 9. It can still be 7 using that logic. The 1 in r3c7 means r3c1 can't be a 1, therefore it can't be 7.
he could deduce it to 2 straight away. r3c1 being 1,2, or 3 to add to 7,8 or 9 is correct. both 3 and 1 is in r3 so r3c1 must be 2 and r3c2 must be 8. edit: but yeah, a rare mistake.
The *689* and *789* triples pointing towards *r8c2* and at the same time forcing both *8* and *9* onto the legs of the zipper in *box 7* were soooo elegant! 😍 And that was just the beginning❗ This is a gorgeous *cosmic-class* artwork. Nothing deserves more to be featured on CTC than *artworks* like this.... ...If there existed a *MOMSA* (Museum of Modern Sudoku Art) in New York this would deserve to be shown there, I guess.
The meta logic in *boxes 1* and *9* was also fascinating. For instance, I figured out a priori that: 🔹in the box containing *doubled 1* *6* = [1]+4 or 2+4 *8* = 3+5 *9* = 2+7 or [1]+7 🔹in the box containing *doubled 3* *7* = 1+[3] or 1+6 *8* = 2+6 or 2+[3] *9* = 4+5
"They're natural, we should keep track of all this," says Simon at around 1:01:20 in. Then proceeds not to color the cells green; the green color he picked to note cells are natural. We love you, Simon.
1:35:33 for me, and I needed a bit of help from the video. That was very challenging! I kept wishing there as an actual anti-knight restriction somewhere in there to help narrow it down, before I remembered that was the constructor's handle!
Very nice puzzle! Pretty hard break-in, lots of combinatorics. Once past that, it solved rather smoothly. I liked the ending as well, very enjoyable. Thank you Simon, your ability to keep track continues to amaze.
At 55:55, I found myself pushing very hard a thought in Simon's brain: ""There is a 7 in the box!". I don't believe in telepathy, but my brain did not care and I felt like I actually contributed to solving the puzzle. :)
1:04:26 finish. Oh Simon, you spoiled a beautiful double deadly pattern by doing that kropki dot too early. If you had done everything else (and left the dot for last), you would have been left with a 6-9 and a 4-7 deadly pattern in columns 8 and 9, only solved by the dot. But no worries; it happens. A very enjoyable return to zippers!
I finished in 108:01 minutes. This was an excellent puzzle from beginning to end. I spent a long time in the beginning memoiring possibilities for box 1 and 9 assuming that r8c2 was a non doubler as I felt this was restrictive. I was able to see that the same digits always showed up in the middle section for each type, the most important being that both contained 7 and 8 and I also knew that each middle section had to have a doubler. This forced a doubler onto the line in box 7 along with 7 and 8 and that is when it broke. The 8 had to have a non doubled 1, but this forced the 7 to also have a non doubled 2, thus allowing no doubler to exist in the box. That was already such a cool opening. Then, I think I spotted my favorite trick of the puzzle. It involved the line that crossed from box 4 into box 8 and its ends. The ends were non doubled from 1234, the next section up were unknown, but their minimums were 3 and 4 due to the geometry extending from the logic before. Now the maximum for the ends is also 3 and 4, which is incredible as they are both forced to be this was allowing an undoubled 7 to be placed in the center of that zipper line. That was such neat logic that felt amazing to uncover. Another amazing part was seeing that for both sides in boxes 4 and 8, the 5 had to appear on the outside. It did't feel useful, but it was neat to spot. My next favorite part came from seeing how restrictive doublers were on the major line from box 5. The line geometry forced r7c4&5 unable to be doublers and this forced the row where the doubler went in box 9. That was such cool logic as well. From there, the puzzle practically finished itself. This was an amazing puzzle that had logic that felt incredible to uncover. I think this might be one of my favorites. Great Puzzle!
You nailed the intended break-in perfectly, which many might consider quite challenging! I’m thrilled to hear you enjoyed solving the puzzle. Thank you for such a detailed and thoughtful comment!
Thank you so much! 5:37 "New York State has dropped away, and Massachusetts flew, and Newfoundland is ice-entombed and Rockall gull-beshatten, where no eye sees the lightning flash its momentary pattern"
I wondered how Simon would break into this one because I only managed it with pen and paper to keep track of candidates! He did very well using only his brain!
I'm a mediocre player, and after determining boxes 1 and 9 had an uneven doubler I started doing what turned out to be the break in logic and found 5 and 7 could not work. It was however so complicated a reasoning path that I thought: you probably just confused yourself! and didn't trust it. Imagine my surprise when it turned out to be right!
Awesome puzzle! The break-in is *extremely* tough, and I spent way too long staring at it, and eventually had to come here to verify that I was on the right basic track. 2:06:43 for me
Well done to antiknight on a great puzzle! Definitely deserving of the feature. However, some feedback to CTC: using 100% LMD ratings as a signal is problematic because of an LMD user who logs his "solve" of nearly every puzzle on the site by looking at the solution that is embedded in the sudokupad page, and generally rates puzzles 0% without ever having solved them. In fact, he's now rated this puzzle on LMD, so if you'd made the video today the title would have been "A 96% Rated Puzzle!" Focusing on 100% ratings is rather unfair for this reason, and unfortunately it's motivating some setters to stop including solution-checking in their puzzles, which avoids "cheating" but also makes sudokupad a worse experience for everyone. I encourage using the comments on puzzles as your primary signal, rather than their ratings, especially for puzzles with fewer than 50 solves.
That’s a flaw in Sudokupad in that case. They should have used one-way encryption to encode the solution. Or keep the solution only on the server, with just an api to check the solution, not to retrieve it.
@@thejuggler42 You could also solve it with one account, and then enter the solution with another account. But simply looking up the solution in the puzzle should not be possible. It should be harder than that.
BTW the best statistic on The Hobbit is that there are now more than 1,000 solves of the tenth puzzle, Lake Town, and after that the other fortress puzzle, Barricade, seems to be the only one that is hiding people up a bit. It is an amazingly well-judged hunt, with some really nice puzzles. And I am sure the solution videos will be very helpful for people who have struggled with any of them - watching a video of a puzzle you have tried is such an opportunity to learn/rejoice that you didn't miss anything.
I think because the 1 in the row is already gone. It can not be 9 either, but he doesn't come to that until later. I think he forgot about the value of the 3 being doubled?
It started as a silly habit of Simon to sometimes sing it. Someone picked up on it and made a song. The video is called "that's 3 in the corner", REM logo on the thumbnail.
Yay for 77! Simon won’t pencilmark thermos but will color centipedes of doublers for 2 digits and won’t carry the 3/4 flashing into box 7 (yet). 😭 Please try not to get covid again.

Another genius setting from you!! Loved the combo of zippers and doublers ! Congrats on this!! Very well deserved and as always much respect for you!
The break-in was a piece of genius, both by the setter and the solver. I needed Simon a bit here, after that it unfolded beautifully.
Thanks Antiknight, thanks Simon!
I got the break-in instantly. Mostly guided by my intuition that the setter would make r8c2 a 5 and a doubler because of course it would be.
@@davidrattner9 thanks David I appreciate it.

*8* = 2+6 or 2+[3]

Very nice puzzle! Pretty hard break-in, lots of combinatorics. Once past that, it solved rather smoothly. I liked the ending as well, very enjoyable. Thank you Simon, your ability to keep track continues to amaze.

lol
lol
haha it happens
I had the same.
I always do that...
Thank you Simon, a great solve.
1:13:30 I love Simon's way of explaining it this way rather than with the 7 and 8 in Row 6 😂
Thank you so much!

Oh no, doublers. I always lose track of those, even when I watch Simon do it.
I enjoy your company every day, Simon. Twice on most Fridays...
I gave up trying to break this in. Kudos to anyone who completed this sudoku.
Zippers line and doublers, can't wait to watch it. That internet wisdom was really sweet.
Under less time pressure today.*Checks video length* Whew, good day to do that one!
I wondered how Simon would break into this one because I only managed it with pen and paper to keep track of candidates! He did very well using only his brain!
57:50 What to do ? Colour R4C3 and R7C6 in green of course !
Wonderful and very exciting puzzle.
Todays knowledge bomb - 6 is less than 7 :)
I'm a mediocre player, and after determining boxes 1 and 9 had an uneven doubler I started doing what turned out to be the break in logic and found 5 and 7 could not work. It was however so complicated a reasoning path that I thought: you probably just confused yourself! and didn't trust it. Imagine my surprise when it turned out to be right!

@@thejuggler42 You could also solve it with one account, and then enter the solution with another account. But simply looking up the solution in the puzzle should not be possible.
It should be harder than that.
This puzzle is so much easier if you just ignore the possibility of 5 or 7 working as a doubler in box 1 and 9
lol there is also a neat trick to solve it very quickly. Just swipe the video to the very end.

Thanks for the birthday shoutout, Simon 🎉😀
Double Six equals Doubled Six!
I found a bit of Simon-esque logic around 1:12:00. If r4 c5 is 1, then there would be no place in the grid for a doubled 2.
10 stars break-in
13:22 who else knew the secret before simon told it😊
1:10:45 Why can't this be 7? I would have said this can't be 9?
I think because the 1 in the row is already gone. It can not be 9 either, but he doesn't come to that until later. I think he forgot about the value of the 3 being doubled?
yeah, he got lucky there.
Great one!
For some reason I really hate the doublers :P
Yeah, I'm iffy on doublers and while I "like" zipper lines, but am awful at them. Watching this one.
The same amount as others or twice as much?
Thank you for the Tiny Dragon ❤
I believe the cartoon is from James Norbury’s book, _Big Panda and Tiny Dragon_.
I wish you wouldn't add a second coloring scheme to a coloring puzzle. That's what the letter tool is for
Does Maverick know he is a frequent co-star of your videos?
3:29 the Tiny Dragon is most likely a shareholder
I always try to exclaim "Bobbins" when i see something Simon has missed.
I usually fail and exclaim otherwise.
Haha, funny joke about the cold. I looked it up it was a balmy 36F. It's highs beliw zero here.
1:14:00 - simpler logic would have been the 47 pair in column 8 between rows 3 and 9.
Even at 1:12:20 the X-wing of 7s in columns 8 and 9 would put a 7 in box 6 in row 5, leaving the only place for the 7 in box 4 in the doubler cell.
1:28 LERROYYYYYY JENKINS!
44:22 for me. messed up one marking that cost me at least 5 minutes. otherwise i was happy.
68:28 for me - took me almost half an hour to get a number in.
Rules state 'digits' but should say 'values' surely.
After a slow start, 77 minutes.
And an absolutly brilliant puzzle. I look forward to doing it again when i have forgotten doing this.
Can someone explain to me the 3 in the corner lore? 😅 I’ve been watching for awhile and still don’t get it.
It's a play on The REM song _Losing My Religion_ . Its chorus line is "That's me in the corner. That's me in the spotlight, losing my religion."
It started as a silly habit of Simon to sometimes sing it. Someone picked up on it and made a song. The video is called "that's 3 in the corner", REM logo on the thumbnail.
