- ** TODAY'S PUZZLE **
A simply incredible puzzle tonight from Piatato called Coordinate Arrows. How we missed this when it came out in February 2022 we don't know but we get to put that right now and showcase a sudoku that is surely one of the best we've EVER seen.
Play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. (ie Every row, column, and 3x3 box must contain the digits 1-9 with no repeats.) Digits on an arrow spell out the coordinates for the digit that is their sum. The row number is written on the start of the arrow, the column number is written on the arrow tip. If, for example, an arrow looks like this: (14) then there must be a 5 in r1c4. All the arrows must correspond to different coordinates. Digits may repeat on an arrow if allowed by other rules.

"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.
1:09:30 Simon: I can't believe it. That's not done.
Given 7: he'll never find me!
1:10:02 Given 7: Told ya so.
I love it when Simon proves something for himself and then just ignores that he did that and moves on
You’re talking about 47:00 when he forgets he literally just eliminated the ones from row two in box 3.
Oooh, looking forward to watching this, thanks a lot for featuring it! 😄👀
Absolutely incredible puzzle.
Nori nori! (:
@@CrackingTheCryptic Thanks a lot! I actually had a dry spell for several months after setting this one, because I knew how unlikely I was to ever be this lucky again. 😂 I loved the video! Great explanations, awesome entertainment, just all in all tremendously enjoyable!
I also have to give a shoutout to my friend Aaronymous, who basically invented the ruleset based on a vague suggestion that I gave him. He also has a magnificent (albeit very hard) coordinate arrows sudoku that is well worth checking out!
This is quite a masterpiece! Thank you for setting it!
It’s brilliant, Piatato! It took me nearly 2 hours but I loved every minute. So many amazing a-ha moments in this one. Thanks so much for setting it.
The look on Simon’s face at the end, the absolute happiness, has put a smile on my face as much as watching the solve.
Ooof! 88 minutes. Mind-bending, but not monstrous.
You know the feeling when you're trying to keep track of too many things in your head, and suddenly *poof* -- they're all gone. Happened a lot tonight.
This solve definitely goes into the "Simon saddles himself with eccentric notation choices" Hall of Fame. 😂
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.
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).
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)
How many times is Simon going to ask “can we put 7 on an arrow?” and keep disproving it? 😂
🤣
I am absolutely thrilled to see this puzzle featured on your channel! The logic found in this puzzle is absolutely stunning, from the global break-in idea to the disambiguation using r3c3 and all the way through the rest of the puzzle. Congrats to Piatato!

1 hour, 13 minute video came out 18 minutes ago. This comment was made 5 minutes ago
13 minutes for all this data. I wonder if it actually watches the video at a higher speed to pick up all the individual phrases or if it just scans the subtitles to count
@@DuncanGDA processing audio can be done at a rate much faster than it takes to listen to the audio. Basically, it looks for the ups and downs that correspond to words in the sound wave. Looking for patterns in the sound wave can be done at any speed.
After this video, you're going to need to adjust the coding to count how many times Jobby Jobby is used too 😂
@@leighedworthy145 3x jobby jobby from 1:07:44 on
the timing is wrong, it puts it after he says the phrase/word and not at the start
Wow! Loved this puzzle! I spent over two hours grinding through it.... then once I understood the key to it, I had to restart it because of some previous mistake, and then completed it in about 17 minutes, absolutely adorable. Now I want to watch your solve!
This has been avaiable for ages!
YES.
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!
Just settling down after a trying day (actually 3 days) with a 🍷to watch Simon and then Mark and relax. About that kid’s puzzle - do you have to prove you’re a child to get access to it. 🤔. I know an adult (me) who would like to try it… 🤪
Glad settling down and able to enjoy our 2 favorite cracking the crypters.😀
I think we are all a child...at heart..so should be able to access the puzzle. 😁
@@davidrattner9 😁
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.
I was so proud about finding the diagonals thing... only to discover it was Simon's first and immediate deduction.
Oh and I took 46 minutes to solve it, I thought I had struggled more than I did
Cool!
My time is 50:45 and I thought I was pretty quick this time 😅
@@victoriam6569 Any time I manage to solve, I consider it a win
@@tirocska yeah! 👍
Just another masterpiece of construction. Every day this channel brings it.
Very lucky and honored to be part of it. Thank ful Simon that you and Mark are the 2 captains of this magnificent ship guiding us on this incredible infinite journey.
So many things: I can't possibly remember everything I was thinking, but a couple of things I do remember. Mark sent this to you knowing that you would love it - it was great fun to watch you solve it. And thank you as well for explaining the 'nori-nori' comment that I have heard so very often in your videos - now I might try to go back and figure out what video that was and watch the original. Your reaction to coming up with "easy" things after working hard on them was very amusing, too! See, there are too many pleasures to recount in this video. Thanks, Simon.
From the catalogue it could well be czcams.com/video/NCUveHxyZZo/video.html (the original Norinori video)
@@tonyvanderpeet5683 Thanks for the link - I just watched this video and it was funny and wonderful!
@@emilywilliams3237 Back then someone made a video with Simon saying nori nori czcams.com/video/na9azkXEueo/video.html
@@yadiracamacho499 That was perfect. Thanks for the link!
I love how SImon looks at these types of puzzles and goes "this can't be solved" then promptly proceeds to solve them by hook or by crook.
Absolutely wonderful! A lot of videos seems to hold the best sudoku you’ll ever see, according to the titles, but this one really stands out for me. Beautiful and elegant ruleset, good flow in the solve resulting in a very entertaining video 😊
Surprisingly approachable, and a lot of fun.
Awesome solve…I’m still working on solving medium hard normal sudoku puzzles…lol
This is over the top clever. And so original. And Simon I think you did need the opening thinking, just to get a handle on how the referencing worked. Simply fantastic.
46:16 For me, I loved the way the logic mostly made in one corner of the puzzle slowly forced everything else into fold
What a joyful puzzle! Simon is brilliant, a joy to watch this solving!
I think this puzzle has melted my brain...😵💫
Simon you always make this look so easy. I have played sudoku for years but a lot of the ones you solve I honestly wouldn't comprehend where to start even if my life dependents on it.
This was beautiful! Well done Piatato and well done Simon!
48:13 (over two sessions, rather spaced apart from each other) ... I spent 20 minutes on this one, then had to step away for a bit, and only recently returned. I'm glad I did.
Wonderful puzzle!
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 found it so satisfying the moment of realising that all indexed cells must be in the top left half of the grid... and everything else followed on from that really smoothly. Top work
I survived this puzzle, with some difficulty. Despite seeing where to look for the break in very quickly, I still had trouble wrapping my head around how best to proceed. Amazing puzzle setting. Now to watch Simon and what I presume will be an amazing solve.
I would normally have given up quickly on a puzzle with an hour long video, but I persisted because of the promising title and was rewarded well! Beautiful puzzle. Beautiful enough that I watched the full video (and shouted "pencilmark the arrrows!" many times).
2:18:55 - What an amazing puzzle. How on Earth did Piatato come up with it? It took me a while to get started but gradually it all fell into place! So chuffed to have finished it unaided.
This one took me quite a while to get going, but incredibly beautiful to solve. Was a pleasure to watch.
WOW 👏👏that puzzle
“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.
What an incredible puzzle!! Thank you so much for this, it's a day-maker
Genuinely great puzzle. Loved it.
what an incredible solve of an incredible puzzle
I am completely amazed at the beauty of sudoku. Thank you Simon.
Absolutely beautiful puzzle. Very glad I decided to watch instead of solve myself on this one. Not sure I would have found the break in with the no 7's 8's or 9's on arrows. If it's even a "break" in, it may be more of a "small crack" in. The puzzle did not relent haha. Again, absolutely beautiful.
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.
I definitely do watch more than one CTC video a month. That said, this was genuinely one of the most unique, thrilling puzzle I have solved in a long time. It gave me the feeling I got when I first discovered the channel and the world of variant sudokus. Hats off to @Piatato and to you simon for the great recommendation.
people are proud for having solved it. i am just proud having been able to keep up with Simon's logic and track of thought
47:22 literally screaming internally as he fails to see that not only is there a 1 on an arrow in that box, it is specifically on the arrow tip.
Took me a while but I'm quite proud at having solved this one. Thank you Piatato.
That was quite an intriguing story
Of digits in full number glory.
'Twas marvelous, thrilling.
Enchanting, cool, chilling,
Fantastic, wondrous, nori nori!
absolutely insane, thanks for the solve
What an incredible puzzle. Definitely one of my favourite videos, up there with sudontku and balanced loop.
This is an incredibly cool puzzle, which I'm quite pleased to have solved successfully.
I really like the concept of cordonates sudoku, it reminds me of the slingshot one you did earlier
And i really like the meta from preventing 9/8/7 from being on arrow, cause if we answered the question once, we answered it for all the puzzle
Enjoyed this puzzle very much. 55min for me, Beautiful logic!
79 minutes to fill in the arrows, 84 total. Mostly figuring out the bounds on number of each number on the arrows.
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. Without that dive into the underlying patterns of the whole (and they were not obvious!), I don't know how fruitful it would have been working out the possibilities of box 9.
Without your very delightful help I would never have realised how not having a 9 on an arrow knocked successively at 8s and 7s. Well, not in under a week of intense staring, without toilet breaks.
I'm new to sudoku and variant sudoku and this was so much fun! The joy I feel when I make breakthru in logic solving these is quite amazing. This was a brilliant puzzle, thank you for sharing this. :D
I am proud i was able to figure out the break in to this one. I usually have trouble with puzzles featured in longer videos. Unfortunately, i had a lot of difficulty keeping track of my pencil marks/colouring as well as keeping track of whether something was a column or row and ended up making some mistakes leading me to restart. bit over an hour and a half of enjoyable solving! I didnt notice the 8 ones on arrows bit. That was brilliant.
39:54 finish. Love the logic gradually eliminating potential target cells, everything flowed nicely. Excellent!
This is very enjoyable with the multiple colour palettes. I put a center digit pencil mark into the possible target cells, though, to only have single colours in the cells.
At 20:00 I'm sat here stressing over the r2c4, r3c3 and r4c2 triple and whether that can have 2 coordinates pointing at it or only 1...
Wow! A fascinating puzzle and brilliant solve! So great...
I love to see Simon completely ignore the giving digits while doing sudoku
I remember him saying in another video that he is getting so used to empty grid sudoku that he is turning blind for black digits. Since practically all digits are blue.
Wow! That was a mind bender (for me)! I almost gave up at the midway point because I thought I'd hit a fatal conflict (the 1/4 pairs in boxes 2 and 3... for some reason I thought one of those top arrows had to be the 1,1 reference) but then watched the video up to that point and saw you had followed the same logic with the same conclusions. That gave me the gusto to carry on.
I wonder if you ever get burnt out doing a constant two videos a day, then I realise I like to do 4-5 puzzles during my day
But imagine sitting down for an hour walking an invisible audience through it. That’s a lot of work.
@@johndaily263 I don't know if it's the CtC effect, but I've caught myself a few times thinking out loud
Simon not being able to see given digits when doing sudoku always makes me laugh
This puzzle is awesome! I absolutely loved it! So much fun!
Brilliant. Excellent.
One of the things I really love about these videos is getting to experience the beautiful logic underlying puzzles I would never, ever be able to solve on my own without oodles of ugly bifurcations.
This might be my favourite puzzle of the year so far. Took me 82 minutes but it was fun the whole way through.
Ow wow, i was in no mood to start this one for myself. Especially with so few solves prior to Simon tackling it.
Maybe i will start this.
What a magical puzzle. Solving it ( after ages ) made me feel like I was lost in a jungle. But I managed it without support, only once I had to compare it with Simon in order to know if I was on the right way.
64:15 for me. Beautiful puzzle!
My favorite part of the puzzle was thinking about ones on arrows
Two minutes into the rules Simon goes like “what??” I never heard from him, makes me looking forward to this!
Did it! 126 minutes, had to restart after 96 minutes, and a glance at the video to check my idea was sound.
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!
Epic puzzle yet again. Mark needs a shout for finding this gem.
What a beautiful puzzle!
28:30 My jaw literally dropped. Very cool deduction!
This puzzle is absolutely amazing
Beautiful puzzle
63min for me! An amazing solve, one of the best puzzles I've ever done!
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.
Awesome!!!
Thanks
Very good puzzle. Quite the solve.
I’ve never known a video be late! I was getting withdrawals!
Sorry, tonight has been frantic and Mark and I were trying to set up OBS to record what we hoped would be tomorrow night's video (see the video intro!!) Looks like it might be Wednesday or Thursday now as it's taken ages to even get the screen record working!!!!
@@CrackingTheCryptic never apologise Simon! The free content that you guys create goes above and beyond. And the help it gives people with their own battles (me included) is immeasurable. Thank you from the bottom of our hearts!
@@CrackingTheCryptic Sounds like a good streaming opportunity!
@CrackingTheCryptic Will the collaborative solve video be on the main channel or just on Patreon?
Super excited to watch it if you’re uploading it here :)
It should be on the main channel. IF we can solve it!
Very nice variant , a new one where i didnt need to watch the video for further explanation.
Still amazes me the mental math/memorye these guys have....ive written so much on the side. And
Managed to ask the right q? (#1s) before watching their video.
Also found it interesting he didnt color the arrows to track the sums
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.
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. You say the 4 in c1 must be green but there seems to be a few valid ways at this point to place 1-3 1-4 and 2-1 on arrows that would let you place the 4 in c1 in r5c1 for example
@@vishvananda I can explain it more but I don't know what u are talking about. I said 4 at R3C1, not R5C1, not R2C1
@@vishvananda starting from 58.06, u can place a 4 at R3C1.
This is because we know either one arrow pointing to 1 at R1C7 or R1C8, two arrows pointing 1 at R3C3, and one arrow pointing to 1 at R7C1, that means we have at least 4 green cells appear at column one!
@@vishvananda if we have something like x-->y
x means which row and y means which column
One thing I like about variant sudoku is how different rulesets play to different people's strengths.
Piatato setting this puzzle ..."If I put this 1 on two arrows it'll flummox Simon" *laughs in evil*
This was one of the most delightful puzzles. All the deductions felt really rewarding to figure out and there were no places to get stuck otherwise. Took me 33:51 which feels quite good for my level.
Simon records his videos several days before putting them up so keep watching before you email again.
Simon records his videos several days in advance so keep watching before you email again.
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!
This took a bit too long 😬
The way he kept doing the long proof, when dude you've already limited the green cells to rows/columns 1 to 6... 😄
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).
I thought I was progressing well through this one until I got to a cell with no options left. So I watched the video for a while until it eventually clicked that the arrows are row->column, not x->y! Then I just had to rewind a long way and it went though cleanly on the second attempt.
I just solved Walk in the Mist. That was fun. The little animation when I placed three in the corner was quite a nice suprise.
This was a fun puzzle to watch very cleaver.
Very nice puzzle. Took me 1:08:31, after a few backtracks due to transposition errors.
This one felt like some kind of eldritch magic as I solved it.
Being someone’s 3 in the corner is actually the cutest thing I’ve ever heard. May we all hope to experience a love like that
On behalf of Nicole, I can confirm that she was deeply shocked by appearing on the channel, and extremely happy at the same time 😅 Thank you to Simon for making this possible!
This was incredible. Not only how Piatato managed to construct this, also Simon's solve. I don't understand the puzzle at all xD
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
My time was 37:30 and I wasn't on a speed run. I used the same method as you, I just worked out the deductions once, rather than time and time and time again. There was one thing you missed, which seemed obvious to me - count the green cells in column N, and you have to place that many Ns on tips of arrows. Ditto for rows. If you have no cells in row N, N cannot go on the root of any arrow, if you have no cells in column N, N cannot go on the tip of any arrow.
@ 15:27 "I was hoping I'd get something interesting there" - actually, you would have done if you'd taken your time. You can't put an 8 on an arrow (because you can't index any 9s), so you can eliminate two of the possible five 8s. You said you could have three 6s, but how? You're left with only one indexable cell in C6, and one in R6. If you don't use both of those 7s, you can't use both 6s and you run short of green. When you use those 7s, in box 5, because of the given 7, you can only place 7 in the cell reserved for 8, so you're now down to two 8s, two 7s, two 6s, three 5s one 4, one 3, and one 2 - that's twelve cells.
You can now place the two 8s, the two 7s plus the freebie 7 in box 5. You can't put a 6 in R3C3, because that would put two numbers in C6. Because of the given 6, the 6 in box 4 is in R4C2 and places a 1 in R3C3. Because you can't now have a 6 in R2C4, the second 6 is in R1C5. You can place two of the three 5s, and the 2 in the corner. I paused to get a drink at this point, and the timer was at 4:50.
You now have the coordinates for all except three digits in box 1. There are at least three digits in C1, so you need at least three arrow heads to have 1, and there are at least four 1s in R1, so you need at least four 1s on arrow roots. There aren't many places you can put a 1 on an arrow. E.g. you need a 15 arrow, but most arrow heads see a 5. Some of the coordinates can only go in one place, and generally remove options for the other 1s.
@ 21:43 "So 7 has to go with 1" How? There aren't any shaded cells in C7 or R7, so 7 can never go on an arrow. Once you realise this, you then go on to consider 6 and rightfully conclude it must go with 1, but you fail to spot that in order to have two 6s (which you need), you must have both R6C1 and R1C6, placing the two 7s.
@ 27:08 "that almost feels interesting, because that would rule 6 out of [R3C3]" You can rule 6 out of there anyway. There's only one green cell in C6. Plus, you've already worked out that if 6 is on an arrow, it must go with a 1, which would mean you would have had two arrows pointing at the same cell.
@ 33:14 - you claim you don't know which of the two 6s pointing at R3C3 is the right one. Of course you do. You have to place two 6s, from two boxes. There's only one possible 6 in box 4, so that must be the one. The other must be in R1C5.
@ 47:30 "I was about to say there must be a 1 on an arrow in this box, but that's not even true" Yes it is. There are 1s in R1 in box 3, and there's a 1 in C9 already, so one of the arrows refers to one of the numbers in C1. That's just elementary sudoku. You need two arrow tips with a 5. There are only two possible places, box 8 and box 9. Stop thinking about "on arrows", it's not specific enough. You now have to place one 5 on an arrow root. There is only one place, which also resolves the 24/35 in box 9.
@ 56:15 You're still counting digits on arrows. That's no good. You need to have at least five ones on the roots, and at least three on heads. There are only five possible 1s on roots one in box 2, one in box 4, one in box 5, and the two you already have. You can just write them in. The one in box 5 dictates which is the one in box 2. This means the 49 in box 1 is 9, because you can't place a 6th 1. You need a 4,1 arrow, all the candidates see R2C2, so that's not 4 and there's a 4 in R3C1. This means you need four 1s in tips. This means R7C1 is 1, giving you the 11 arrow.
@ 1:01:24 "Can we put an 8 on the tip of an arrow?" What on earth are you doing? You know darned well you can't! It was one of the first things you worked out.
All you needed for this was to be methodical, but you're so "Oh squirrel!", and get distracted that you just don't follow any train of thought to its conclusion. Stop looking for the next thing until you've exhausted the current line of reasoning. It looked like you were about to see the light with the 5s, but oh no, you started looking at 1s.
@ 1:02:15 "these squares are now 1 and 4" - I wonder which way round they go. Look down! There's a 4 in C8. As a sudoku expert and educator, how are you not ashamed to do stuff like this in nearly every video? I love clever logic, but not when it's used to deduce the bleedin' obvious.
If you had attacked the 1s logically, and split off the tip count, there was absolutely no need for your triumphalism at getting nine 1s on arrows. The only reason it mattered was because you left them festering for so long. I stopped watching at this point. It was just getting too tedious to see your random fire approach mess up a puzzle that was even finer than you found it to be. "If you watch one video this month..." - I don't think so. I'm certainly glad you brought the puzzle to my attention though. It really was a classic.
This was really frustrating to watch. I accept that you may not have seen things as clearly as I was able to, but you had actually worked out the logic you needed quickly, but then took an eternity to apply it. Armed only with what you deduced in the first few minutes, you could have got to where you were at 42 minutes in just 5 minutes. How many times did you have to make (and explain) exactly the same deductions? I got sick of you keep explaining why you can't have digits summing to 9, and each time highlighting the cells on the 9 diagonal. How can you forget something you've already deduced and explained three times? You kept having to work out that 6 could only go with 1, because apparently you couldn't remember that there are no 8s in R6C2 or R2C6. The thing is, you didn't seem to remember, it's not as if you were just being tediously fastidious for those who couldn't follow. You kept working out whether 7 could go on an arrow, despite there being no green cells in R7 or C7, and surprise, surprise you kept concluding it couldn't. Why bother making deductions if you're going to instantly forget them?
Hi Raven Creations. I’m sorry you feel like this, I can understand you finding it hard to watch the video solves when the logic is more obvious than it is being made out to be. However, I think you perhaps underestimate your own solving ability and the fact that Simon alongside his genius does have his weaknesses such as having to constantly reconfirm logic and struggling to multitask. Also, I know that you mean well but please try not to just criticise, there are other ways of being helpful. Remember that Cracking The Cryptic is about showcasing the joy of solving variant sudoku, not releasing frustration (though I get there will be times where that is understandable, just not all the time). I’m not an expert and I don’t want to cause any issue, I just find it hard seeing so many comments which are often more negative than positive.
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)
