This one hurt and was the longest to solve. I did it differently from Mark at first, but we both ended up on the same page. He just... did it 3 hours faster than I did.
@Mark, I feel like you would have benefitted from paying attention to box 7 and the cage surrounding it sooner than you did.... Specifically, due to the knight's move rule, where the 9 cells from the cage fit in box 7 is extremely limited. In particular, the middle cell.
I finished in 61:00 minutes exactly. This was a very fun coloring puzzle that had some awesome geometry surrounding the nine cell cage.I was a little slow, but it was so fun gradually learning more information about each color. Great Puzzle!
66:38, came back to this puzzle two weeks later, didn't remember anything but coloring was involved. Not a BAD solve, just spun my wheels in the middle before seeing the next thing I had to look at. I actually REMOVED all of my coloring at the end. 😮
Finding that blue was 2/8 Mark comments that is quite hard to do 16:20. however from the moment he pencilled it in as 1289 it was obvious it was 2/8 as he had 1/9 in column 7.
I'm currently watching, so I don't know if it was caught, but @31:20, it CAN be in r9c8 because that "red" should have been a red/white flash. Red is either in r8c8 or r9c8.
At this stage, yes. But one look at the large cage reveals it must be same as yellow, and for that reason cannot go in r9c8. Mark sees that a couple of minutes later.
I did the puzzle prior to watching Mark and thought it was complex, but watching Mark "struggle" makes me feel much better :) Not sure what it's rated on Logic Masters, but my guess is 3*?
*Memeristor* published a series of memorable interviews to great constructors, including *Phistomefel, Jay Dyer, Clover* and many others. On this channel, Clover's passionate contribution was particularly fascinating to me (How I set sudoku - Clover).
Very smart and orignial use of multiple interactions between these well known constraints. For instance, at the beginning the *9-cell* cage, together with *KM* acted magnificently to link two palyndromes... then the the short palyndrome starting from *r5c5* was "connected" by *KM* to the long whispers... This puzzle contains a neverending series of elegant and greatly gratifying deductions, and this video shows an elegant way to solve it, notwithstanding a small logic mistake @31:13 that was already described in this section. 👏👏👏👏👏👏👏👏 (KM stands for *Knighty Mcknightface,* the red knight shown by Mark @2:13)
I doubt you were being serious, but I took KM to stand simply for knight's move. Unfortunately, it could just as easily stand for king's move, but if it reminds me there's a chess move restriction of one type or another, it's done 95% of its job, and as such, is greatly appreciated. 🙂
@@RichSmith77 Well, since it's there to remind you the rule, I guess it may stand for the *Red Knight.* Anyway, the only thing we know for sure is that it was put there by the constructor, since the puzzle was published on LMD with the same link, about two months ago.
62:44 for my time. I was also confused about which cells to color and found the way a little bit messy (I'm not quite sure if I used the same path as Mark). A rther difficult puzzle where making a mistake is relatively easy.
2:14 Just earlier this week, I'd suggested putting a chess piece in the description or by the puzzle to give an extra reminder that there's a night's move restriction, and now the puzzle has KM listed right above it! I assume other people suggested it also! 50:59 for me. I think I can do it better in the future!
I really like knight's move puzzles (not only because of Knighty McKnightface), and might give this one a try. The ones in the chess app are very good, too. Thanks for this video, Mark!
You can do it Emily. I took a while, but then had a contradiction. I went back to video and Mark showed where I went wrong. It was just before one of the times he said "you've got to be careful with these sort of puzzles ". 😊
Was really expecting this to use the phistomofel ring, particularly the anti-knight result. It says that at most one digit can be off the ring, and if it exists, it must go in r5c5. This has an interesting interaction with the palindrome line on r5c5, proving that every digit must go on the ring at least once. Unfortunately, all that was pretty useless
Wait, hold up, I could have sworn the time on this video was only twenty-something minutes, not FIFTY-something. I was about to actually try this myself! ...Well, I DID try this myself, and I finished in 57:03. Fine puzzle.
Sigh. At 31:15, Mark falsely claims light blue is r8c9, "because it can't be red". But that red in r9c8 is not solid, it is a possibility, not a for sure. It's lucky picks like this based on bad logic that bug me about this channel sometimes.
But, it's a live solve. If it were a prepared solve, then a mistake in logic would be a failing. But in a live solve surely you must allow that sometimes a mistake might be made, right? Personally, I have learned (through watching other channels occasionally) that the interest inherent in a live solve far, far outweighs the risk that a mistake might be made.
It not a bad one. From the large cage, it is easy to see that it must be the same as yellow, and therefor cannot go there anyways.. Mark sees that a couple of minutes later, but could have seen it as soon much earlier when blue and yellow were done.
@@emilywilliams3237 Yes, that's the whole point of this channel. It's not a tutorial channel where they tell you the step-by-step that they worked out in advance. Never has been, never will be.

Same here. I got all 1s immediately and then my God, the endless colouring and redoing and recolouring...
I love seeing Mark use a bunch of colors, and I love how him and Simon have different color palettes ❤

33:06 for me. Quite a tough one!
Thanks for all your videos, Mark and Simon! Could you make a video on how to set a sudoku puzzle?
The channel has a number of videos where setters from the community explain their approach. Zetamath did a good one a couple years ago.

Completed in 31m04s
@42:00 Your color palette choice for green and violet r6c3 is very pleasing to the eye to see. Thank you Mark!
At time index 6:28, why would 9 be restricted to r9c5 if it were on that whispers line? Why couldn't it go in r8c6?
R8C6 sees both cells in box 9 that Mark pencil marked a 9 (by sudoku and knights move).
@@dustpan5356 D'oh! So easy to see, but so easy to miss. Thanks.
R3C6 is screaming at Mark.
In chess, the annotation for Knight is N as K is for the king.
@@Ardalambdion
That bothered me as well.
71 minutes; but I managed without watching any of the video :)
1:07:03 - A gorgeous colour fest.

3 in the corner.
Simon is pencil Marking. Mark is coloring.
I think the thermo in box 7 is superfluous. I'm pretty sure I never used it for any logic during the solve.
I did use it at one point, so it can be helpful but possible it wasn’t necessary.
I started this puzzle from r5c5.
I initially started elsewhere and got bogged down. Started over with your tip and found my way fairly smoothly. Made all the difference. Thanks!
53:12 ... took me a while (as I was multitasking and paused in between other things to do), but I'm glad to have gotten home on this one
Nice puzzle!
Dang this took me almost 100 minutes. Not my best performance.
Took me ages also, but I thought this chaos was really really fun though:)
Took me more than 2h and an entire color palette
83:41 for me
KM stands for knighty Mcknightface?
I saw that! And also, there is a red 'siren' and a knight at the title of the puzzle! (I do have the cage tool totals on, it's next to that.)
Anybody else have trouble seeing "light blue" ? Looks like basically white to me on all my screens.
This made me sweat a little. Good Puzzle
