Yeah. I think I had that after 2 minutes (colored all the moons and suns and started with the loop in that corner just like Simon, colored it, and then it was pretty obvious that the suns were odd). But I do not recommend forgetting the rule about the loop switches parity between boxes halfway through the solve :-D

The use of a second line color to indicate order of cage visits and not necessarily the exact path of the loop was an inspired and very clever notation choice I may need to borrow when solving region-visiting-loop type puzzles in the future!

That said, green/red is a difficult color pair for us colorblind folks, so if Simon could use a different color for indicating the region order, that would be greatly appreciated

The parity was available from the start. @16:18 you have 5 Suns. Has to be odd, and both lines have to exit immediately.

He probably missed it because it's very surprising to be given the parity that early. I had to triple check that I was doing things correctly because it seemed like I shouldn't know the parity right at the start.

I was shouting r3c3 = 5 in this solve for the longest time. Could have been the first digit on the grid. The 22 and 28 grids completely tile box 4, with r3c3 leftover. The secret that Simon and Mark only share with their closest friends says box 4 adds up to 45, so r3c3 = 22 + 28 - 45 = 5 Thank you for another great solve :-)

That has to be the most relatable thing for most of us. As soon as I saw that many cages I was like "alright time to look for 45s", shaded 2 regions to mean they sum up to 8, and got the 5. Instant. Then I proceeded to get COMPLETELY stuck. Made some guesses but eventually decided to check the video to see what I was missing. And of course Simon is doing the craziest logic while that five is still unaccounted for, for almost an hour. His mind is beautiful.

This was the first Sudoku from this channel that I solved! Don't laugh, I battled with it for 4,5 hours. I had to start over a few times because multiple times, I was close to the end and realized I'd made a mistake. I'm proud I powered through this and tried until I got it right.

One of the puzzles I could solve without checking the video! Took me 164mins (with interruptions). Not great, but I did it! I like the loop puzzles a lot. Absolute brilliant setting, the way the loop and the parity supported each other at times. Now I get to watch Simon solve it.

The constructor definitely knew Simon's habits of shading odd and even digits. I mean, sun and moon, day and night, orange and blue, odd and even. Brilliant.

@timdorr

8 ай бұрын

Also, sun and odd have the same number of letters, as do moon and even.

*Simon:* figuring out the moon’s parity at 34 minutes after nearly closing the loop *The five sun cells in box 7 since the beginning of the solve:* am I a joke to you?

I like how Simon takes until 34:30 to find out moon was even when he had 5 sun squares in box 7 since 15:50 (meaning they had to be odd).

Congrats on the Debut, ElChiglia! Excited to see how this puzzle goes!

Earlier today I watched Simon solve “The hardest sudoku of all”, over 2 hours wonderful solving, from 1 year ago. And now I’m looking forward to watch Simon solve this exciting puzzle.

lol that convoluted reasoning about the corner cage using parity, when we knew the parity of the symbols before the loop even left box 7. xD

I was screaming about the 5 suns in box 7 deducing that sun is odd, and moon is even, for soooo long. It then made going around the grid with the parity to help with the line much easier.

(For the uninitiated, "hoopy frood" is a good thing. It's a Douglas Adams reference. It means Simon's a cool guy who knows where his towel is. (Leaves a virtual chocolate cupcake with goopy icing)

This was an amazing puzzle. Well done ElChiglia!!

This was my favorite puzzle in quite a while.

This looks like a lot of fun!!! Look forward to watching all the way through later tonight! Later: It is fun! I did see all the way through! 😄👍🏻

Solved this in 37:25, I had to check why it was lower than the video time (it normally isn't). Not seeing from the start that the partity could be determined from the 5 digits on the line in box 7 changed the solve quite a bit, I'm impressed that it could be solved without it.

This was lovely! I really enjoyed constructing the line, which flowed brilliantly

Loved working this puzzle today both figuring out the path and then the sudoku after.

This was such an enjoyable puzzle from start to finish. However many stars this was, it is the goldilocks level for me. Just perfect.

46:51 When I first spent a couple minutes looking at it I felt a bit lost. But I put it down and came back to realize that it was actually quite obvious how to progress. The loop ended up flowing very nicely. A very nice puzzle!

I managed to figure out the parity of all but four cells in around twenty minutes, made basically no progress for the next ten minutes, and then decides to watch the video. Which then reminded me that the 3x3 boxes were a thing, allowing me to fairly smoothly solve the rest of the puzzle. Apparently there were so many cage lines that my mind forgot that boxes exist.

I kinda tried it myself, glancing at the video for hints if I got stuck, but was able to finish mapping out the loop and coloring in all the parities mostly unassisted…then my brain went flat beyond getting more than a few digits placed. I was satisfied enough with what I did and just watched the video for the rest from then on. Was still very fun

A very fun puzzle with great flow! 27 minutes for me. This time I had to go gray for moons and yellow for suns, and stuck with it even after determining the parity.

This was fun and not too difficult! Just the right level of difficulty for me!

Amazing how our brains see things differently. The very first thing I saw was the 22 cage and the 28 cage with one cell outside the normal 45 cage meant the digit had to be 5.

68:51 By far my best time on a Sudoku so far when comparing to Simon's time! This puzzle was an absolute blast!

This was a fun one. Took me 55 min I also found it a lot easier to just block off where the line can't go with a red line surrounding the cages it already went through. Removes all the X's and it's not as cluttered. Also as a fun treat I made the suns yellow and moons medium gray because it's thematic lol

22:36 for me, started in box 7, and got the parity of the sun/moon right away within the first minute, then after loop & parity shading, all even digits were done.

Those moons and those suns are so amazing! There is no difference between the day and the night in this sudoku!

10:49 - Ah, the joys of unedited videos. So, oddly enough, you'll shade orange in odds, and you'll even shade even in threes in the corner?

I found the 1\7 pair in box one through the secret. The 32 cage only left 13 and with the 5 in r3c3 and the parity being odd meant that 1\7 was the only option to total 13. This in turn led me to see the 9 in box 7, it was just a different path than Simon’s to get there.

Ooh, love pencil puzzle hybrids!

It's interesting how the rules don't specifically state the core rule of the underlying pencil puzzle type; rather it arises (if pretty straightforwardly) by implication from the stated rules (if you're not familiar, in Sun and Moon rules the rule is just that the line must alternate which symbol it visits each region visit, which here arises from the combo of the line must alternate parity and symbols are linked to parities)

57:36 - Absolutely gorgeous.

solved in 42:18. the trick of using odd/even parity to construct the loop going through all the cages was very clever, especially when you continue building the path by already marking all the evens or odds in a row, column, or box.

Simon, did you notice that Sandra & Nala had four puzzles on that list and no one else had more than one. I guess that says something about the quality of the puzzles of Sandra and her furbaby.

Happy to squeak in under an hour at 59:58!

took 2 hours 10 minutes. it only took about 30-40 mins to find the loop and the rest to finish it. it is a really nice puzzle

What a fun puzzle. I solved it with only 2 'hints' from the video. very happy with myself :)

Ayyy 35.05 for me today!! Good morning from New Zealand!!

34:42 on this. Very enjoyable! I always like when I can colour in parity in the whole grid before typing a single number 😄

51:12 for me - finding the loop was a decent difficulty. This one combined parity logic, cage logic, loop logic, and all sorts of tactics.

Nifty! Just over an hour total, but I again made the mistake of trying to solve while sleepy and the last 10-15 minutes was mostly useless until I forced myself awake and saw the obvious 3 which resolved all the remaining odds. Anyway, about 20 minutes to solve the loop and then half an hour ish for the rest of the puzzle!

Quite approachable and fun. Used blue and yellow for day and night. Restarted after 15 min because I mistakenly thought I'd made a mistake. Finished 2nd attempt in 25 min.

18:37 for me. Great puzzle, very enjoyable!!

32:40 for me. Coloring puzzle of even/odd parity, followed by figuring out what numbers were possible where.

It's immediately apparent , because I saw a few comments, that @15:51 , there are 5 (five) cells on the loop through those "suns" in box7. Therfore; the "suns" are Odd. I think Simon's thinking too much about the "Country Roads" thing ( and whether a cage can be entered and exited more than two times) and missing that. Suns are Odd, though (I wonder if that would have changed Simon's solve ( he'd be able to employ the "bishop's move" on Even and Odd parts of the loop - I don't know how though ). Hmm..🤔 Gonna be fun, though. 😂☕️🎃🎃(

It also has to immediately exit the box I'm noticing. (No more "Odd" cells in "box7") I wonder if Simon sees that another way.? Hmm.. again. 😂

33:21, a crazy solve. I did make a mistake at one point, assuming ALL the unmarked cells in a cage had to be the opposite of the marked cells, but was able to solve from there after seeing where I was wrong. Even undoing all the odd and even pencil marks at the end was a bit of work.

My time was 54 minutes..... same as Simon. Very pleased with that 😄

15:56 could have determined sun was odd in box 7. There were 5 cells on the loop in sun cells and there are only 4 even digits.

The knights move puzzle yesterday was a bit too one dimensional

Hi, Loved this puzzel! you could have figured out the party already in box 7! That helped my solve!

Cool puzzle, only took me about an hour and I always feel slow at loop puzzles.

I can feel my brain melting trying to understand

Love that he comments about blue orange bring best for color blindness, then differentiates from his green line with a red one. 😅

Finished in 49:37. Thankfully I caught the parity in Box 7 pretty much right away. Unfortunately I somehow stuffed up somewhere between box 5 and box 8 and couldn't unpick it, so I had to start over about 15-20 minutes in (I kept the timer running, for a change!)

Ooh, so many other possible deductions and early digits before completing the loop. I did it slightly differently.

36:51 for me. Beautiful puzzle!

A fantastic puzzle - finished in 35 minutes, largely by not getting distracted and going down blind alleys, and realising quickly that the key was going to be finding a route path that alternates between sun cages and moon cages ... then noticing that there are 5 sun cells in box 7 which fixes the parity completely. An interesting point with this rule is that if the path hits two adjacent cells (and doesn't go to another cage in between), you can never prove that it doesn't go directly between them - there is nothing in the rules that could prevent it from closing there.

I started it myself and i just made moons blue and suns orange because although i didnt know what was odds or evens yet i had to start somewhere. I got as far as gia twenty minute market but with a few extra lines then he did because right side stuff . His using the cages values is what i suspected was next but i stopped and came back before i did anything else.

The pronunciation of "Chiglia" will be something like "Keelya".

around 23:30 after R9C9 was out of the loop R8C9 is also out of the loop bc you have to exit to R7C9 -->Moon Moon You cant tell if the loop takes R8C8 and R7C8 but it continues to R7C7 R6C7 R6C8 R5C8 R5C9....

34:35 for me. Easy but a lot of fun!

How do you set a variant sudoku puzzle in sven's sudoku pad? I see them on the channel here but in the sudoku pad itself I can only enter in a classic style puzzle. I don't see a way to enter cages or little killers or anything like that. Is it even possible? or only for content creators?

19:38 "Ah" . . . Points around box 7. Oh good, he's noticed the 5 Sun parity digits, locking Sun as odd. And also fixing the line in the 13 cage. Nope. . . . Ignores for the rest of the puzzle.

22:39 Or counting the number of sun cells in box 7 would also work. Now, I did manage to get all of the loop, the parity and 7 digits before starting to look at the video, so I wonder how far in this will be before I go "Doh"?
