"Maybe we should have started in box 9". "Yes, we definitely should have started in box 9". However, the logic in box 9 required 100% of the logic used before Simon looked at box 9. Therefore, Simon found the foundational logic and followed it.

Great explanations, awesome entertainment, just all in all tremendously enjoyable!

Simon, I've been following the channel for a while now and it's fascinating and endlessly entertaining to watch you solve these puzzles. Up until now, I've not had the inclination to try to solve one myself, but the praise for 'A Walk in the Mist' at the start of this video and the fact that over 15000 people had solved it made me finally try my hand at it. I cannot put into words the 30 minutes of joy I experienced as I managed to put the first digit in the grid, then the next and the next and (with a 3 in the corner!) so on all the way until the end. I know there is a good chance you won't read this in the plethora of comments, but thank you from the bottom of my heart for introducing me to a wonderful world of sudoku I never knew existed. I am definitely hooked.

[@ashnikchauhan9103]

You know I have had the exact experience with this channel. I started by just watching Simon solve, which was relaxing & engaging, a much needed pass time in pandemic. Then I started solving alongside him, watching the video little bit and then going on by myself as much as I could. I really do encourage you to keep up solving whenever you have time. It really is greatly rewarding activity for the brain like going for a run. BTW It was my first 3 in the corner(A walk in the mist).

[@zakwinduss]

I was exactly the same. It was the first time I’ve tried one of these more “high level” sudokus and even though it took me an hour it was such a mental reward, and what a magical feeling as it all fell into place. (And yes that jolly 3 in the corner)

[@stevepinard5826]

20:30 (spoil) : You could rather see that columns 789 and rows 789 do not contain any green, so 789 cannot go on an arrow, no matter the final sum (as spotted at 41:50). Wonderful puzzle, I loved solving it, and I loved Simon's solve of it! Thank you very much for sharing such gems!

[@notmonroe5575]

I'm happy to say I was able to solve this Sudoku. It took me about 4 hours and 15 minutes to get there. I rather quickly figured 7,8,9 weren't going to be on an arrow and that the 6 always needed to be accompanied with a 1. After an hour and a half I got the first digid in r3c3, when i realised coordinates needed to all be different. And it let me to both 1,6 and 6,1 coordinates. I had to use pen and paper for the rest to help me visualize the options. So I thought my approach would differ completely from Simon's and was wondering how he would go about it. Interesting to see his approach was quite similar to mine, but he was just quicker to spot the things and visualize the options in his head.

“How am I going to indicate that?” My solution was to use the line tool to drop circles in the six possible cells that could be referenced by the arrows in box 9, then remove the circle from the one that wasn’t a box 9 reference when i figured that out. I also used changed referred-to cells to the darker green once I found which arrow was pointing at it to keep track of who still needed a reference arrow completed.

[@martysears]

Epically good. This is my favourite sort of puzzle, the sort that makes this channel so great to watch. Fairly simple rules to grasp, but with far-reaching and unexpected and delightful consequences.

I was making my colours a bit overwhelming and picked up a new strategy from Simon which kept it clean and simpel. That helped a lot. I also did a lot of candidate notation and instead of full numbers in the beginning i did corner notation. And finally it all dropped together, jippie!

[@Rubrickety]

This is an incredibly cool puzzle, which I'm quite pleased to have solved successfully.

[@grithog5399]

If Simon had been considering arrow tips vs. arrow ends when counting options for certain digits (like the 1s and 5s), it would have cleared everything MUCH faster! For example, column 5’s green cells are a completely different set from row 5’s green cells, so the 5s you need to place on tips have nothing to do with the 5s you need to place on ends.

[@vishvananda]

Really fun one. I ended up solving by marking all the arrows that had to start and end with 1s after limiting to 12 cells and dealing with box 9. That really opened up the puzzle fast. The key point to make it work is you can rule out r2c2 because with putting a four in the box would prevent you from placing a 1->4 arrow anywhere! Then there is only one allocation of 1s that gives you 8 ones on arrows.

[@khoozu7802]

Even better. When u knew there are 4 arrows pointing to 1, that means all the 4 cells at column 1 are green, so R3C1=4

@@khoozu7802an you explain further? I feel like I’m missing a step in your logic. I don’t see how you choose between r1c2 and r2c1 for the 4 at this point.

Have to say, Simon, it was in no way a mistake to have started in the top left corner and uncovering that diagonal patterning of the possible referenced cells.

18:28 You can do slightly better with the 6s (has the same effect on the count but gives progress on the shading) - you can eliminate 6 from rc3c3 entirely: since that indexes a sum in column 6 for two different arrows, and the rules say two arrows cannot index the same cell, that would require two different sums in column 6, and by shading we know it's down to only one possible target cell in that column.

Very nice puzzle. Took me 1:08:31, after a few backtracks due to transposition errors.

Not that you really needed more colors at the end, but just a reminder that you've got other colors tucked away. Brown, peach, dark purple, and dark blue are all different enough from the main palette to use I think (plus they're all customizable).

What a beautiful puzzle!

[@tomsamper4345]

I had no shot at solving this one myself but I am pleased that I was able to make some of the general deductions about the puzzle… side note I can’t tell if I was laughing, crating or throwing a bloodclot at 1:09:30 when Simon said the 27 pair in R2C8 couldn’t be placed as it was solved by a digit we’ve had literally since the beginning of the puzzle, the given 7 in R5C8 I know, I know, the tendency is to sometimes overlook the given digits because he’s kinda training on the blue ones that he’s filled in, but that moment still had me screaming at my screen. Overall however this was a very fun puzzle to watch you solve thank you for tackling it.

Once past the beginning two steps, (1) determining area of interest and (2) understanding box 9, then you need to look at 1s. You have a ton of them to put into the grid. And you can't put 22=4 in the grid because then there won't be places for both the 14 and 41 (along with the other 1s). So, you need to find homes on arrows for the following: 11, 12 (or 21), 13 (or 31), 14, 41, 15, 61, 16. That's 9 ones! And you only have 8 boxes to work with because box 6 has no arrows! So, it's lucky the one arrow is doubled up in box 1. But then, you can work out the positions of all the ones, and elimination gives all the partners, and then simple sudoku finishes it.

(Actually placing the 14 arrow is still easy if you put 22 in the grid, just 41 immediately has no place to go anymore)

I'm at 22:38 so if Simon figured this out later in the video, I'll try to remember to delete this...but you can tell at this point that 7, 8, and 9 can never go on arrows for a much simpler reason than what Simon is using: no cells in those rows or columns are green! Edit: he did eventually figure it out at 41:31!

[@jorrr9096]

This took a bit too long 😬

[@SomeRandomGuyOnYouTube]

The way he kept doing the long proof, when dude you've already limited the green cells to rows/columns 1 to 6... 😄

[@chipsounder4633]

Epic puzzle yet again. Mark needs a shout for finding this gem.

[@Capataro]

Dang, I got the break-in but somehow didn’t spot that 7 goes in r4c4 so I was stuck. Still proud I got this far because I am super new to this

[@bobogaulout]

Beautiful puzzle

[@rickwoods5274]

You kept saying you "should have started" in the bottom right, but I disagree: You just ("just") needed to use your green more. Start looking at which row/column combos are possible by just looking at your green cells (which of course requires you to do the work you did to make them green in the first place)

Very good puzzle. Quite the solve.
