The Sudoku Grid Is ALL Fog??!

** TODAY'S PUZZLE **
We celebrate Missing A Few Cards' birthday today but trying another of their collaborations with Full Deck called I'll Cry If I Want To. And this puzzle might actually make you cry - it's a 'fog of war' sudoku with no cells revealed at all. Mark tested it and said it was VERY hard. Simon attempts it in a video and can confirm this assessment... but it's also as clever as you'd expect from two eminent math professors!
Play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Along modular lines, every set of three contiguous digits has three different remainders when divided by 3. Numbers outside the grid give the sum of the first X digits (the "X-Sum") along that row or column, where X is the first digit seen from the direction of the clue. In addition to any modular lines revealed as the fog lifts, every X-sum forms a hidden straight modular line at least X cells long starting from the cell closest to the clue. Digits separated by a black dot are in a 1:2 ratio. ALL blacks dots are given. As correct digits are placed, fog will lift, potentially revealing more clues.

FD and I enjoyed this SOOOOOOO much!! Thank you for the birthday wishes and the song about 3 in the corner! We're happy we could torture you with 2-8-age. Loved the solve! And enjoyed the popcorn during the movie :) Time to plan ahead for the next milestone ... :) -- MaFC Also, many thanks to Sven for the new animation and working with us to have this puzzle be the debut of that lovely addition. And Simon, you followed the solve path pretty much exactly as intended ... it was just a tad tougher than our usual fare :) --FD

@BrooksMoses Год назад

Simon! At 1:10:00, you were right about there being another way to get this set of deductions. With the 4 placed in row 3, you could have used the 24 sum to figure out that that r3c7 was a 6, which would give you the 6 in r2c6, which would have given you the rest of c6 from there -- basically getting the same information in the opposite order. Not necessarily a lot faster, but your intuition was indeed correct. I did see the 4 in box 1 a bit before you did, but I couldn't find that finish at all either. (Interestingly, I don't think the 819 line at the bottom is needed; by the time that was visible, your 4 in box 9 would have resolved the 14 pair in c5, which resolved the 16 pair in c3 that you used that line to resolve.) This was a fascinating puzzle!

@SilverEchoes Год назад

Not only did we get the long-awaited "all kropki dots are given" rule with a grid completely devoid of dots, but we got it in the most beautiful way possible with the uncertainty of dots until the reveal at the very end. The resulting suspense and comedy were very entertaining. And then we got Simon's utter and baffled glee at the celebratory three in the corner! That brought a grin to my face and I had to rewind to watch the surprise over again. This installment of Cracking the Cryptic was a long solve with some tough spots in the middle, but the payoff at the end was sheer delight. Thank you so much, Sven, Simon, Full Deck, and Missing a Few Cards.

I did this puzzle in 57 minutes on a train ride home, purely logically and without bifurcation. I didn't even find it too hard, except at a couple of points. It was like a free-flowing fun self-unfolding puzzle, the kind I really like a lot. So I couldn't believe it when I looked at the video length and saw that Simon took nearly a full hour longer than me. This is easily a record for beating the video solve time. I'm definitely gonna watch this and see what the snags were.

Over quite a quaint and curious fog-befuddled sudoku- While I grappled, never cheating, suddenly there came a greeting, As of something gently tweeting, tweeting from the yonder blue- "'Tis some visitor," I muttered, "fleeting by me with a clue-" Quoth the birdie "Doo-doo-doo."

Quoth the birdie "Two-two-two!"

@Paul-cn3ij Год назад

With a free afternoon ahead I thought I'd give this go and see how far I could get. Amazed to finish this in 45:54 without a single mistake and no need to watch the video. Started on row 1 and after a few minutes reduced the x sums to 5/6 in both cells and quickly proved there was only one combination that would work. So I think Simon starting in column 9 slowed him down. The other thing is I pencil mark like Mark so the negative restraint on 1-2 ratios sorted out a lot and that's not a Simon thing! Great puzzle and I must say quite proud to have done it so quickly in comparison to the master.

@justscrobbler1897 Год назад

@RoselynTate Год назад

See, I had that thought too, but after watching him explain the rules I decided to give it a try myself, and managed to actually solve it! There are lots of little deductions to be made around the negative constraint, and you have to find the right place to look, but I don't think any of the individual steps are necessarily all that hard to figure out -- the hardest part is just someimtes figuring out where to look for the next deduction, which is kind of hilarious given that the reason I usually like fog of war puzzles is that they usually help guide your eyes to where you need to look next in the solve, lol

I used to be the same, but knowing Simon's penchant to take the most difficult route to solve puzzles, these days a long Simon video is just an invitation to beat his time - which wasn't too hard to do today. His refusal to pencil mark cells makes him waste so much time. There were naked singles all over the place today that he just never saw because of his elitist attiude to pencil marking.

@poppymcdermott837 Год назад

@@ceevio_art hit the nail on the head. Simon could literally halve his time, probably more, if he would just pencil mark. It becomes convoluted for no reason.

@tangrybird04 Год назад

Omg I can’t believe I actually solved this! I opened the puzzle just to see how far I could get, thinking I wouldn’t actually finish it….but thing I’m most astonished about is I solved it in less time than the video length!!!! 1:33:16 ❤❤ Edit: I hate to say it but I’m going back on my solve and I ASSUMED there was no black dot between r8c2 and r9c2😮

@GrahamNicholson56 Год назад

This took me over 2 hours to solve - and it was worth every minute of it! Clearing the first of the fog with the break-in was so satisfying. Thank you to the setters, Sven for the nice surprise and of course Simon.

@neokart2660 Год назад

I put the three in the corner right at the end very satisfactorily. I'm new to watching videos on the channel, but I've never seen any recent ones, so I finally know why that curious three in the corner effect appears in the puzzles I solved, but not in the videos. Thanks for such good content.

@EelcoWind Год назад

45:29 for me, but I did use some paper to check which numbers could be used in the X-sums when the clock wasn't ticking yet. So in total around an hour, I think.

@laomedondardanos5658 Год назад

At 1:08:55: "I think there must be an other way to notice it". You are right: I noticed it by looking for the 1/4/7 in C6 and notice that all are set (4 and 7 are known and the 1 need to be in R4 or R5) and like you argued before R2 C6 cant be 2/5/8, so I noticed it need to be from 3/6/9 and knew what it was. An other thing I noticed before was: In R6 we knew that 2/5/8 need to be in C3 and C5 and one of C7/C8, so R6 C4 could not be from this set and therefore the only place the third number of the 2/5/8 set in box 5 needs to go in R4 C4. It is an interesting constraint which is really hard to keep track off. I used coloring to help me a bit.

@RichSmith77 Год назад

I think also at that timestamp (1:08:55), the 24 x-sum in r3, the 1-7, 2-8 pairs always have to sum to 9. It's very similar to the situation he had already looked at in r1. 1 couldn't go next to 2, and if it was 7 with 8 you would already have 24 before adding r3c7. So they were either 1-8 or 7-2, summing to 9 either way. Making r3c7 a 6. (Which was another way to get the 6 in box 2.) The 1-7, 2-8 pair having to sum to 9 was a repeating theme. It also applied in c5 at one point, to give r2c5 =9.

INCREDIBLE! Well set and well solved. Monstrous in a joyous way. And Sven with the absolute W on the 3 in the corner!

@Kinada Год назад

Holy crap I finished with 44 minutes on the clock! I saw how long the video was last night and thought, no way can I do this, watched the intro for the rules and paused. I ended up not having time to even watch the video so I closed it to watch tonight instead. I ended up not being able to sleep and spent that time lying awake thinking about the puzzle. I ended up solving the 27 clue in my head and limiting the other 3 clues by quite a bit and tonight decided to check my work in the puzzle before watching the video. Putting in what I came up with was correct and made the next step with the 24/26 clue interaction much more limited and most things after that seemed to flow rather nicely. I can't believe that I got such a time even with the extra time spent thinking about it when I should have been sleeping.

@davidmahoney9877 Год назад

Gentlemen, that was just this side of brutal. I feel no shame for my 2 hours 45 minutes. Realizing how, exactly, the modulus and sum rules worked together to force the x digits for the x sums was a very interesting break in. Brilliant puzzle. Stay Awesome

@rontyson7941 Год назад

Took me 4 and half hours but I was also watching tv the whole time. :P

@cgstreet08 Год назад

Great puzzle. 67:53 for me. Simon, you missed the naked 6 in box 2 at 48:48, which would have shaved about 20 minutes off your time. Candidates for r2c6 are 1,2,6,8. The 1 is on the modular line in column 6. The 4 in r1c6 rules out 2 and 8, leaving the 6. Then candidates for r3c6 are 1,2,8, but the modularity of r3c5 knocks out the 1, leaving a 2,8 , which sets the modularity of r3c7 and r3c8, and so on.

@CrazyIvanTR Год назад

One of the rare times I was faster than Simon, my time is 01:19:15 but this puzzle is playing towards Simon's weaknesses :D After seeing the line is entropic and that every 3 connected cell on the line is divisible by 3 you have to appreciate that whenever there's a 4 on the x-sum clue's start that means the total is going to give a remainder of 1. The same applies to 6 as well, it will always give a remainder of 0 on an x-sum clue. So the only clue where 4 can go is with the 25 and the 26 clue cannot have a 6 or a 4, which means it has a 5. The 5 however can give a total that is divisible by 3 as in a combination of remainders 2-1-0-2-1 so it could go with 27 or 24 if allowed by the other digits on the board. (I got all this within like 2-3 minutes after reading the rules, of course I'm abysmal at normal sudoku and the last 3 rows took be like half an hour...)

@martinepstein9826 Год назад

Wonderful puzzle. Each step is difficult but no step is monstrous. At the very end all you need to notice is that 4 and 8 can't be next to each other in row 7, hence one of them is in r7c2.

@sm3ttz Год назад

Simon,. you are a MASTER in explaining, no worries about that. So clever puzzle and clever solve.

@emilywilliams3237 Год назад

This was so very fun, your being bamboozled is never dull, your brilliance at making deductions and explaining your thinking - and your reaction to that confetti when the 3 in the corner was unveiled - so wonderful! Thank you, Simon.

@markp7262 Год назад

1:17:11 finish. I did color the different modulo sets, which helped me with the modulo, but then I missed the negative constraint for a while. But definitely a fun puzzle!

@drewskavich Год назад

An amazing puzzle. A challenging solve. I'm glad I gave it a shot before watching the movie. I did get rightly stuck. Watched along until Simon unearthed a small bit of logic I'd missed and resumed solving. Got stuck again. Watched more of the proceedings. Got another nudge and was able to finish this beast. I then had to watch the remainder of Simon's quest.

@ronjohnson6916 Год назад

The 4 in box 1 was indeed available for a while. But I don't think it mattered much. I see why Simon prefers to keep his pencil marks as meaningful as possible -- it's just the way his mind works when grinding a tough puzzle.

@JasperJanssen Год назад

It wasn’t just available, his pencil marks showed it as available; If nothing else, putting it in would have lifted a few squares of fog, although, granted, probably not much more. But if course you only know that it didn’t show much after said fog lifted…

@stangerrits6712 Год назад

Quite a cringe to see him remove the pencil mark in R2C2, but not looking at the consequences

@ronjohnson6916 Год назад

Yes. But I'm used to grinding through dense pencil marks. It's almost the totality my toolkit on a puzzle like this. You can see Simon dismiss box 1 as being consequential several times. I think the number of pencil marks is a short form for "no weak squares here" to him. Whereas I am always, well I got something. Let's see if it leads to anything.

@LarkyLuna Год назад

For people who aren't good at divisibility or have kids watching along, since the num pad is 3 by 3, all the column share the same number modulo 3

Great job, Simon. I'm proud of you for persevering.

@krist39 Год назад

This was such an amazing puzzle, I love the "all rules and almost no numbers" ones. Took me about 5 hours! Looking forward to watching this video tomorrow to see how you did it (too tired right now), but I'm guessing your start wasn't quite as exhausting. I actually spent an hour or two working on all the possible combinations before I realized that the remainder of the sum could be used to determine the value of X.

@CaptainSpock1701 Год назад

18:42 - "OK, this is obvious. That is not a four" - If by "obvious" you mean that you totally lost me, then yeah. It is obvious!

@Adrian_Grey Год назад

Really proud of my time on this one: 56:27 I love the combination of the X-sums also being modular lines, very interesting logic there. And the kropki rule was clever, you can guess about halfway through that there won't be any dots, but you can't assume anything until the fog's been cleared. Loved it!

@rwthomas111 Год назад

Very excited to see a full length movie fog puzzle!

@fawful9992 Год назад

I love how the rules mention black kropki dots and then the puzzle doesn't even have any.

@andrewjanssen8663 Год назад

I was at 56:08 into the video when I had a moment of revelation and saw that r3c9 had to be 5: because r3c6 must have the same modularity as r3c9, and the only remainder 0 mod 3 number left in box 2 is 6, which would put two 6's in r3.

@brianarsuaga5008 Год назад

I said in another comment that I was scared off by the video length, but I couldn't help myself. And I did it! Once again I'm really, really impressed by how the fog of war mechanic makes puzzles that would be VERY difficult EASIER by limiting your search space. Also, what a GORGEOUS puzzle with a funny twist that I was very suspicious of almost from the start.

@solfeinberg437 Год назад

3 in the corner - almost the last number in. I thought It was saying - almost done - almost done. Had a little fountain of confetti!

@Tyranisaur Год назад

In videos of the past the puzzle has had a ruleset where a constraint could have been worded in the same way as the black dot constraint in this puzzle, but were just given as a global constraint. But wording it it like this plays exceptionally well into the nature of the fog. Since there are negative constraints in play, discovering nothing when you clear the fog is useful.

I did this puzzle while stuck in an airport which gave me plenty of time to finish it one amazing deduction at a time. Not to spoil it too much, but there is a nice birthday surprise near the end of the solve.

Lorks, you need nearly every sudoku trick in the book for this one, barring set theory and swordfish.

@brianroberts7096 Год назад

Once Simon explained the rule set, I was up and running. Got stuck a couple of times until I remembered the negative dot rule. Had to watch the video once (just to check what I had done so far). To the point where Simon gave a big clue about the top row in box 3 adding to 18, then seemed to forget about it. Forgot to restart the clock, but was about 90 minutes. Waited until the end for 1 black dot to unwind everything, and was confused when it wasn't there. The 4(79)8 in box 7 took a bit of spotting. Loved the puzzle.

@windybeach2184 Год назад

I used the drawing tool to highlight the hidden modular lines, and colour coded the 3 digit sets. That made it much easier to visualise the patterns across the grid. It’s rare that I beat Simon at a puzzle, so this was very enjoyable!

Solved this one all my own! In only about 3 hours too! Remarkable puzzle, the fact that *spoilers* there wasn't ever a single black dot in the puzzle really got a smile out of me. That 1:2 ratio negative restraint pretty much sets a good 80% of the puzzle, it's really nice. And the fact that this puzzle ends with a 3 in the corner is a very welcome sight. This puzzle had such a wonderful ruleset and kept me excited to play more the whole time, one of my new all time favorites. A grand recommendation by me, and happy birthday Missing a Few Cards, marvelous work :D

@missingdeck9999 Год назад

@jameshornback8602 Год назад

I took the step you took at 1:47:32 a little further an noted that If R7C3 was 3 then both R8C6 and R9C7 were also 3. By the logic you pointed out R8C3 would have to be 1 so R9C3 had to be 6 therefore R9C8 would be a 5 making R8C8 a 6 and placing a 3 and a 6 on the line. Meaning R7C3 could not be a 3. Then the rest of the solve came pretty quickly as the rest of the puzzle fell apart.

@DMPearson91 Год назад

respect for the commitment and uploading the whole thing in its full raw recording

@Nevir202 Год назад

1:42:49 it's at this point, I'm seeing, everything comes down to where 8 can go in r7. If it's in c2, then 8 is there, and if it's in the only other option, c6, then 4 is there in c2. So that cell is always 4 or 8, and that forces r8,c2 to be 7,9 which places 4 in box 9. That loops back around and solves the 4,8 placement in r7. EDIT: As usual, he came to the same conclusion by FAR more complicated means lol.

@RichSmith77 Год назад

Agreed. I viewed it as "where can 4 and 8 go in r7, remembering they cannot go next to each other without a black dot". One had to go in r7c2. Boils down to the same thing. 👍
