JC, pouvoir ne pas avoir demontrer que le 5 ne peut aller que pres du 4? La ligne de whisper n est pas forcement continue. Sinon impeccable comme toujours. Merci enormement pour votre travail. Un admirateur 😊

Just my speed. Thanks!

Thia puzzle does not follow its own rules. The chess move apart is ignored. I have entered the same numbers a chess king's move apart, and it accepted it. When I entered the numbers what the game said was "correct", it was against the rules.

This is very hard. It took me several attempts, the final one taking 4 hours. My solve took three steps. One: find options for each set of modular numbers. I gave each of 147, 258 and 369 different colours. Then, established which colour each cell could be. For the two number sets, 258 and 147, there was an option. So, one set became numbers in the corners, the other in the middle. Then, I chose one number set and went until it failed. That established which colour was which modular set. From that point it was very, very simple.

There is no Sudokupad link.

I *really* enjoyed that puzzle! 25:15 for me. 😄

This was hard. Because the video was not in English, I had to really figure out how to do this type of coloring puzzle. Merci!

This was fantastic! Wish I could understand French so I knew what you were thinking. I actually could get some of it by the pointer movement.

Remainder lines are broken, or the directions are wrong

Beautiful solve path! Thank you JC

I’m amazed that enough high school French stuck in my brain that, 45 years later, I can still work out the rules to the puzzles here on your channel. 😄

This looks like a great puzzle, but I couldn't quite understand the parent/child relationship rules. Just so English speakers know, the LMD link has an English version of the puzzle complete with a solve that makes it all crystal clear. Eventually, we will all speak French if these puzzles keep coming 😂

Excellent puzzle, and not hard if you pay attention. Like you, I used a combo of letters and colors, but I distinguished between the two flavors of Vs and used a-d and e-h, which was redundant but seemed like the way to go when I started. You are so good at knowing where to work.

A very elegant construction. Lovely logic throughout, especially in the grid's 'top' and 'bottom' cages (and resolving the 27 cage also) 🙏

Good job figuring out the break in. Nice puzzle!

Tres agréable et interesante - merci beaucoup...! 🙏

Thanks for featuring my puzzle! ❤

Où est-il indiqué dans les règles qu'à 07:32 le "2" doit être dans R9C2 ?

Really fun! Of course, I did it the hard way. After hacking through the weeds, I decided to step back and find a better direction.

Solenoid and Semiconductor are two of my favourite puzzles from the ones I've made, thanks for featuring them!

Merci, monsieur. This was very fun. J'amie les fins 'non-Hollywood'.

Nice one JC. Thanks.

Wow…!!! This is a wonderful puzzle and incredibly elegant. Just amazing how it unravels slowly but surely with the loop continuously being forced. Loved it! 👍🏻

The link seems to be the same link to Mod Pods JC 🙏

Very nice solve! You followed the intended solve path pretty much exactly. The key is to slowly work your way towards that "middle cell" (trying to avoid spoilers) at which point the puzzle slowly untangles.

Great puzzle!

Je ne parle pas français tres bien, mais merci pour jouer mon Sudoku!

I used the link, I think the puzzle flipped

Great to see you making videos again after a long break. My algorithm has only just let me know, so I have a few to catch up on.

Genial! T'as parle un peu a la fin de la surcontrainte. C'etait fais expres parce que je voulais un sudoku de 2/5 etoiles. Si tu veux un sudoku un peu plus complique, j'en ai un qui s'appelle "Concentric Pairs" dans la CtC sudoku testing submission chaine de Discord ~3/5 etoiles. Aussi, j'en ai un autre qui s'appelle "Sous le ciel de Paris" dans la chaine monthly puzzle prompt ~3/5 etoiles. Si tu as des sudokus, j'aimerais les essayer!

Quelle surprise...additional linked puzzles...!! 'Daytime Sleeping' was pretty tough but very satisfying to solve - an amazing construction. (I'll leave 'Three Is A Crowd' until tomorrow!!). Merci bien.

Merci JC Godart! This one was meant to be very approachable to introduced battenburg and negative constraint. Hope you enjoyed it and everyone else too!

Thank you for this great puzzle. Your solve was so impressive to me because I could only get bits and pieces of the break-in on my own. I don't understand most of the French (except the numbers), but the way you approach the puzzle makes it understandable anyway.

Thanks for solving my puzzle!

Tricky but great puzzle - worth sticking at...!!! 🙏

Nice solve!

An excellent puzzle to mark your return to posting...!!! Thank you JCG/FD&MAFC.

Oooh! What a lovely surprise! So glad to see you posting solves again; thank you for the feature :)

Welcome back! It's been so long since you posted that I thought you had given up youtube for good. So this was a very pleasant surprise. Beautiful sudoku. I do like the modular constraint. Took me well over an hour, but very enjoyable. Many thanks.

I found that shading the digits 5-9 as 'high' made the whole puzzle much more approachable (after initial struggles 😆). Great design and solve!

Love your solves! I just finished watching them all!

This can be solved more easily if you simplify your notation by using *placeholder digits,* provided you know how to use them properly. You can safely use them up to the very end of the puzzle, if you ignore the *disambiguator* (which is the weird rule about the corners of the grid). I would not be able to solve your way. You followed two "parallel" logic paths at the same time, I followed only one of them. But you are so good that you were faster than me, even though your notation was twice as complex. So, you probably don't need placeholders as much as I do, but others might. Moreover, *placeholders* are fun, elegant and powerful 💪💪💪 when you know how to properly use them, but learning requires time. This time, I learned something new: *Modular lines* are insensitive to the transformation *y = 10 - x* Any valid sequence of digits along them remains valid after being tranformed that way❗ This is also true for *German whisper* lines and *renban lines,* as I learned when I started using placeholders, a long time ago. Because of that, each placeholder digit *N* can be safely used without *loss of generality* (i.e. without "removing ambiguity") to represent either itself or *10-N.* For instance, I started by placing *7, 2, 9, 1, 8, 3* along the upper line, being aware that they represented either themselves or their complement *3, 8, 1, 9, 2, 7* Placeholders are not a *guess.* They are symbols. They remain *ambiguous* up to the end of the puzzle, in which you verify compatibility with the disambiguator. If they are not compatible, you just switch to the alternative configuration by applying the above mentioned transformation to each of them. This final transformation is fun and can be easily done in the blink of an eye (about 45 seconds) if you know how to do it properly.

Simon (Cracking the Cryptic) solved today using placeholders, but he also used colours. As I wrote above, I believe they are not needed. You want to simplify notation as much as possible if you want to minimize the risk of making mistakes.

Global entropy is a neat rule I haven't come across before. This was a really good puzzle, well constructed. I found it tricky to scan at certain points and I'm glad I had the video to consult for a couple of hints.

Very cool puzzle, and quite tricky! I found that the solution checker works if you write large digits in the sudoku grid, but only pencilmarks in the outer ring.

8 minutes in you got a 46 pair in box five. How did you eliminate the 5 from those squares. not seeing the logic to get rid of the 5 possibility at that time.

I don't quite understand why at 22:38 the loop can't turn up in R5C8 and enter box 3?

SamuPiano here - good solve! This followed my logical path the whole way, start to finish! I'm glad you enjoyed it!

Thank you for featuring Irregular Chaos! I mostly make smaller puzzles but i do occasionally make 7x7s and 9x9s. Great solve on this one!

Great puzzle!
