What an absolute privilege to have my puzzle featured on the channel! I completely agree about the grammar and I apologise, to be honest I wasn’t sure how to edit it after it was published. I’ll be more careful if I set another…! Thank you to all for taking the time to solve it.

Don't be silly, easy to mix up "proceed" and "precede". Great puzzle 👍

I'll admit I haven't watched this channel for the last couple of weeks. I'm glad I popped in for this one. My 41 minute solve won't break any records, but I'm happy with it. I usually end up at about an hour with these puzzles in sub half hour videos, if I can solve them at all.

My first number was R2C5. 2+3+4+x > 9 => R2C5 = 1

I couldn't believe he started out pencil marking r2c5 with the options 123. He only ruled out 3 by independently concluding there couldn't be a 4 in the next cell (r2c6) first.

Me too.

solved in 6:08 - nice pattern! a hidden useful thought based on the rules is that if you place a 1, you can put the 9 before it, so it works in reverse, and that helps

13:47 I'm a huge fan of Escher so I loved the theme and the puzzle used it well.

Adored the disambiguating arrow in bow 3, just like yourself Mark. A delightful puzzle that took me just under half an hour to solve myself. Really loved the interplay between 9s and 1s.

Ever since I first saw the Labyrinth movie back in 1986, I've always been a fan of the artwork of Escher. Quite interesting how one of his iconic pieces can be converted into a Sudoku puzzle.

Finished in 20:58. This was a strange puzzle, but it's so similar to a thermo sudoku, my favorite variant, that I was able to pull through.

22:48 ... after failed first attempt. Awesome puzzle idea.

Finished in 11:56. Fairly approachable and straightforward variant. Loved the Escher Thermos! Fun puzzle!

Loved this - I have several Escher prints on my walls, so it was wonderful to combine puzzling with art. I actually managed a solve in a reasonable time, too!

29:24 for me. Very cool to think about thermos with undetermined lengths and starting points, but all arranged along a track.

Great puzzle! For some reason, I kept wanting to increase counter-clockwise, er, anti- clockwise!

I found the wording of the rules confusing, and initially tried to have the staircases going the wrong way, but it broke fairly quickly so I figured I must have misread them. _Edit_ - having just read some other comments, it looks like the rules have been amended to make them clearer, that explains why!

What an interesting concept for a sudoku puzzle!!

26:00 Not an amazing time, but a great puzzle, and I'm always happy when I can solve a puzzle from CTC without help from the video.

Great puzzle, Chris! thanks for setting!

Interesting variation and a nice 20 minute solve.

Palindromic time of 23:32 for me, ending with what else but a 3 in the corner. A fun little puzzle.

00:22:03 for me. Fun puzzle, with a nice bit of logic to get going! Kind comment.

16:57, not a great time, but interestingly had a *very* different solve path. I started by placing the 9 and 1-5 in the central box, which Mark didn't even get to until nearly the end of the puzzle. Probably more efficient to do it Mark's way, but I didn't even look at the easy numbers around the outer staircase until I had the inner one mostly figured out.

The directions in the version I clicked on say that "each digit is proceeded by a larger number" which I read as "each digit is preceded by a larger number", which made the rules for the 9-1 relationship quite impossible. I probably spend 5 minutes trying to puzzle it out before taking a look at the video, where the rules say (much more reasonably, I think) that "each digit is followed by a larger number". It's quite odd, at least in America, to see "proceeded" used in this fashion. Might I suggest taking pity on those of us who aren't so linguistically savvy and changing it back to "followed"? Once I got past that, it was quite fun!

What a fun puzzle to solve! (30:52)

29:02. I started with c7r8 - the circle comes before the square and it has to be a larger digit so it can only be 9 and 1.

Lovely. I even finished it by myself

Great ruleset, this was fun solve - took me 31:42

3620@#1634. That was a smooth, pleasant solve for once, as opposed to all the ones I've had to struggle with in recent weeks. It only took a bit of thinking and careful pencil-marking to resolve everything. Nice.

Great puzzle! I don't try many, but I tried and solved this one and really enjoyed it!

This video is almost shorter than today's wordle in a minute! Just kidding, love you Mark!

10:48 ! Love it :)

Beautiful and funny puzzle.

12:35. Super easy. Barely an inconvenience

Lovely puzzle. 19:02 for me

What a lovely idea. I adore Escher's work so brilliantly illustrating the mobius strip. However the ruleset provided with Sven's sudoku pad rather spoiled my experience of it. "each digit is proceded by a larger digit in a clockwise direction" is such a weird way of putting it. To me it was disambiguously the opposite of what was meant, although as I type this I realise that it is not wrong. I read proceed as precede so it was my fault. However the wording on Mark's solution page was quite clear, so when I read that I scrapped my impossible interpretation and restarted.

17:12 for me. Nice puzzle!

7:16 for me. This has to be the greatest disparity between a day's Mark and Simon videos, at least for my solve times if not their own. Simon's took me almost 2 hours if memory serves.

Escher thermos should be a new ruleset: like regular thermos, but 1 is considered greater than 9.

I was only 2 seconds slower than Mark! Very proud :)

24:20 - Very enjoyable.

This was a lot of fun, completed in 11:44 (conflict checker off), many thanks to Chris Savvides for a very cool puzzle!

I didn't watch the video but I spent a few mins confused because in the sudokupad it says each number is "proceeded by a larger digit in the clockwise direction" instead of "followed by".

The two boxes you called out at 3:45 actually were what you said by the end, hmm

12:14, once I figured out the middle it was easy.

00:38:17

I hate to boast but yet again I observe that 800 people did this in a week while I did the same puzzle in half an hour entirely on my own!😏

14:37, really quite easy.

Design begs the q? Are there 3 other solutions based on the stairs direction?? Interestingly you dont need the directions constraint...4 branches 1 breaks due to sum..2 break due to too high or too low digits on the loop. Reminds me of the roses/wheel puzzle that took simon 2hrs (oh 7-8 hidden thermos one

Im unclear here , @6:35 , "a 9 will always be followed by a 1," the rules say. Does that mean a "1 must always be preceded by a 9?" Why can't it go 8,1 in there for example? And "9" still possibly in the circle? Puzzle language? Thanks

It cannot go 8-1 because every digit other than 9 (so 8) has to be followed by a larger digit.

Thanks for explaining that the Patreon puzzle doesn't start with Sudoku. I took one look and then chucked it - not a fan of snake puzzles that have nothing to do with Sudoku.

Please anyone help me out here, it seems mark and all of you are assuming that if there is a 1 then there must be a 9 before it, but that is not how i understand the rules. Only if there is a 9 it has to be followed by 1. But if there is a 1 there can be say an 8 or 7 before it. As it doesnt have to be consecutive. Im only oartly into marks solve but it seems all his deductions so far are based on this false premise. For rxample at 8:27 he assumes 9 must be in one of two cells in row two so that he can then transition into a 1 but that's not the rule. What am I missing?

@raminafchar4412

25 күн бұрын

Yes, same here with me. I learned to read the rules carefully. So I did not "reverse" the rule "a 9 is followed by a 1" to "a 9 is before a 1". Took me a while to came to a lot of 89 and a few 789 pairs. At the end I had a a final 78 pair that I could only resolve by putting a 9 before the 1. Wish that that would have been a bit clearer by the rules...

@nikolausseydel1728

25 күн бұрын

Well, it follows from the rules: Any digit has to be followed by a larger one, except for 9, which is always followed by 1. If you have an 8 in a cell, the next cell must be 9 (otherwise it breaks the rule), and the one after the 9 must be a 1 (also according to the rules). What follows is: Any 1 must be preceeded by a 9, that's indeed not part of the rules, but you can deduce it from the rules!

@stevieinselby

25 күн бұрын

Every digit going up the staircase must be higher than the previous digit, except in the case where 9 is followed by 1. That means that no other digit can reset back to 1, the only option to follow an 8 is to increase to a 9.

At around 6:10 I don't understand why he insists a 9 must be in the 'staircase' in box 5... Cannot 9 be in the circle in the very center and 1-8 is in 'staircase? I may be too drunk for this, hrumph...

It is not allowed to go from 8 to 1. So the 9-1 Pair has to be on the staircase.

19:31 for me. took me too long to crack the rules. i wasted a lot of time.

I'm very confused you read "proceeded" 2x (around 3:25) when the text on the screen says "followed" --- and "proceeded" is what's currently written on the sudokupad instructions too. Proceeded is the opposite of followed!! [I started the solve by looking at the same arrow, but immediately concluding R2C7 necessarily was a 1 (as 2-3-4 breaks over the fourth digit) but that was wrong...]

"Proceed" is not a transitive verb; it's strictly intransitive in both British and American English. Therefore "proceeded by" in the rules as currently published is nonsensical. It should either be "succeeded by" or "followed by" (as it is in the video).

@@benwhite5734 "None of them list it as a transitive verb" Well, that's not what I asked you. Or, to be more precise, this doesn't answer my question. The conditions "verb not listed as transitive" and "verb listed as strictly intransitive" are not the same. The main part of my question, and of your comment, is the word "strictly". Is there such a thing as a "strictly intransitive verb"? And if there is, certainly "proceed" should NOT be STRICTLY intransitive. Because English speaking people say phrases like "you may proceed with ...". I can agree the word is NOT usually used with numbers. Only God knows why, because "preced" is used with numbers and it is the opposite/dual of "proceed", isn't it? And that's so weird, because the thing happens with "preceder" and "proceder" in Portuguese. We may say "1 precede 2", but we don't say "2 procede 1", we say "2 sucede 1". Man, I need a linguistics expert now. Hahahahaha. Why this happens?

The rules in the app are not the same as those in the description. 👉 In the app, _"proceeded by"_ (or even _"preceeded by")_ makes no sense. It should be _"followed by."_ By the way, this was a nice puzzle, although it turned out to be quite easy.
