- Here's where you can pit your wits against Now the People Will Know We Were Here by ViKingPrime: app.crackingthecryptic.com/7m...
Normal sudoku rules apply. White dots separate two cells containing consecutive values; Black dots separate two cells where one value is double the other [1:2]. Values along a purple Renban line form a set of consecutive, non-repeating values in any order. Values along a yellow Nabner line form a set of non-consecutive, non-repeating values in any order (e.g. if a cell of value 3 appears on a Nabner line, then values of 2 and 4 cannot appear).
There are 9 Hot cells contained within the grid comprising a set of the digits from 1 to 9. Each row, column and box contains exactly one Hot cell. There are nine 9 Cold cells contained within the grid following the same rules as the Hot cells. A cell may have only one of these roles. Hot cells increase the value of the contained digit by 1. Cold cells decrease the value of the contained digit by 1.

5:58 Rules of today’s puzzle
8:43 Start Of Solve - Let's Get Cracking! - Zábava
I was the tester (blueberrypug) on this one- it took me 2 hours!!! not a push over at all. such a good puzzle, thank you ViKingPrime!!
ViKingPrime checking in - beautiful solve Mark, and the best birthday gift I could possibly receive.
A bit of a spoiler to follow (but not much): I myself used an aide-memoire while setting, however I benefitted from having it list the opposite values - the Hot and Cold digits needing to be placed. Once you've resolved the Hot/Cold digits in Boxes 2, 4, 5, 6, and 8, what jumps out is what the cold digit is that must exist in Row 1, and therefore what the cold digit is in Row 7, and therefore what the Hot digit must be in Row 7 and so on... it cascades in a very pleasing manner and I'm so sorry you missed out on that particular joy!
It would've been a bit of a time saver too but it's particularly tricky thing to spot and I'm so glad you persevered despite it.
That's exactly how I solved it! The level of satisfaction it brought was indeed immense, especially as it took me 5 hours to spot... Great setting for sure and a fun solve!
1:14:05 seems like a mistake, that was not a "cold digit-9" pair, it was a definite cold 9 somewhere. Four could not be ruled out, because it would have been a genuine digit.
This had me yelling "NO!" at the screen many times :)
I was in an utter panic when he made this false deduction!
Took me about 2.5 hours. I got stuck for a while because I forgot the 1 in Box 2 was cold and forced the cold 4 into the other column. I had to come to the video for help and as soon as Mark mentioned it I rushed back to the puzzle and was able to finish it off.
This was a wonderful puzzle. I thoroughly enjoyed the ruleset combination, and felt that it was applied in a beautiful way.
I'm just excited that we got a nearly 90-minute solve from Mark! As someone who loves watching the challenging solves, it's a rare treat to see Mark tackle one of these!
Being patient while watching long solves is an important part of practicing mindfulness.
This must be a hot-5 stars difficulty😎
A very clever puzzle.
A couple of things that Mark missed that might have helped.
From 38:25, r7c7 couldn't be a 1 as it would need a hot 1 above it on the white kropki, repeating 1's in the column, so it was a 3. (At 39:20 he asks if it could be a cold 3 above it, but fails to realise the cold digit in box 6 is known to be a cold 8 to make the renban work).
From 53:30 (although, it's more obvious once he switches his aide-mémoire around, at 57:10), what is the cold digit in row 1? There's only 3567 available, and there's already a normal 357 triple in the row. So it has to be a cold 6 in row 1, making r1c6 a 4.
Mark still solved it faster than I could, though.
@39:16 I think Mark could have placed the 3 in R7C7 here (finally placed by other means after 53 minutes). R6C7 could not be a cold 3 as the cold digit in that box must be 8. It's therefore a hot 1 or a natural 4, either way it has to pair with a 3 across the white dot.
This was indeed a head-wrecker of a puzzle, even just watching! Your aide memoire was helpful to you, clearly, and it also was to me to help keep track of what you were looking at. This kind of puzzle has the look of something rather easier - a lot of markings in the grid, relatively understandable rules ... UNTIL the hot and cold digts get in there, then it gets extremely complicated. Thanks for persevering, Mark. I admire your stamina, both physical and mental, to sit in the chair and work on one challenging puzzle for nearly 90 minutes!
Brilliant puzzle with a qutie difficult start.
I am so happy I did NOT try this by myself! (of course the length of the video had its merit to make me choose 😄). I think I would not have been able to solve this by myself in a thousand years. This is the video I rewinded the most, since I am following CTC (I went back at least 7 or 8 times to understand what the heck Mark is doing or taking about) - and I consider myself a very good solver. Hat off and deep bow to Mark here!
DNF. I gave up when I though all possible combos of black kropke between box 2 and 5 were eliminated. I totally didn't think to consider a 5 -10 value pairing. Over 45 minutes and nothing to show and barely and digits. Very challenging though so good job by creator.
I LOVE cold and hot cells!!! And also VikingPrime's puzzles.
57:01 for me. Wow, what a puzzle!! Loved it!
Hard but beautiful. I have found the main properties of the box 2 but lost the trace soon after. Chapeau!
It was a pleasure watching you today. This was a very fun puzzle with a awesome solver. It was hard? Yes! But you handle it perfectly!
I loved the "memoir", this helped me. We should have one extra line in this type of hard sudoku to help people like me to understand better the puzzle.
Thank you!! 🤗
Finished in 120:02. Brilliant logic throughout particularly with the constraints limiting various placements. I had to start over a few times because I made some assumptions which lead to some problems.....
Fun puzzle!
*led
Just saying
Ciao though 😂
Franklin, don't feel bad.
I once thought thsd "felt" was the felt on a pool table and "fealt" were the feelings we had.
(I think that's because of the encyclopedia i was reading -- "fealty" and all)
So, don't feel bad about you putting "lead" as the past tense of "lead" when it's "led."
Onto the puzzle now..
Ciao.. 😂

FAQ:
Q1: You missed something!
A1: That could very well be the case! Human speech can be hard to understand for computers like me! Point out the ones that I missed and maybe I'll learn!
Q2: Can you do this for another channel?
A2: I've been thinking about that and wrote some code to make that possible. Let me know which channel you think would be a good fit!
I remember that line from the Heritage Minute.
I like the Inukshuk thumbnail. 🍁
Hahahaha simon with sub 25minand mark w 130hr....the world's turnedover
50:12 How does Mark rule out r7c5 from being a regular 1 at this point?
Nvm, I see that it would force two real 9's into column 4
Kennet thanks you, Mark! Birthdays all round.
Don't worry Mark, everyone is a bit confused by Kansas City. There is a Kansas City, Kansas, you'll have seen it while you were here, even if you didn't know it: We have a State Line Road, and even a building with a state line hallway.
I finished in 245 minutes. This was very hard for me to keep track of all possible hot and cold digits. I, especially, got tripped up on r4c3&7 and thought I had broken the puzzle as I had ruled out every possibility. That is, until I realized that the renban can start behind the number I put in and take its place, so if 2 is it, then the renban could be 134568 with 1 replacing 2. I need to check the video to see if I was messing up. This was tough. Great Puzzle!
What a brilliant solve - I enjoyed watching it very much.
This was insanely difficult for me. I kept breaking it. I don't think I like puzzles where there's too many degrees of freedom. I finally solved it in exactly 2h on my last attempt.
I used a different color to mark boxes where digits typed in are the possible values (green for me)... this one was still ROUGH!
13:36 nice
82:16 for me
Who else thought that was a toilet roll behind Mark?
Hahahahahahahaha.
Lol
Yeah, it looks like that.
Unrolling on the inside, too.
(I used to have a cat-- that's the way to have it -- if on the outside, you're going to find it all unrolled on the floor one morning)
This'll answer that question ("inside or outside?"), because even though I preferred it on the outside as a kid, my wife preferred it on the inside (I think more room for her), but if you have cats, inside it is.
(That, or unless you like a whole roll unrolled onto the floor when you wake up)
Yeah, looks like a "toilet roll."
Good one 😂
I think I enjoyed this puzzle, but I found it quite tortuous at times. That is probably down to my ineptitude.
This was pretty hard…took me over 2 hrs, grinding these numbers…
got about half way through and then i made some mistakes i could not get myself out of.
32:46 Seems a bit odd to me. The hot 6 goes with a normal 8 without issues. Not sure why it was pushed away. However, cold 4 and normal 4 does not work together. Ok, it blew up 13 seconds later...
And I have absolutely no idead how a hot 6 and a regular 4 would bond over a white dot.
I suppose in the end it was just lucky there, because there was no solid deduction between 32:46 and 34:49.
The deduction was solid once he corrected his error (which only took a few seconds for him to find). The 4 in box 5 is cold, and the 1 in box 2 is cold, therefore they could not appear in the same column. Regular sudoku rules out the 4 in the same column. Therefore, out of 1248, the 14 are ruled out of the same column as the 4 in box 5. That leaves 28 above the 4, and 14 above the 6. The 6 is hot, so it can’t go into a cell with a white dot above it because there’s no consecutive value. So the only way the arrangement works, as he explained, is for the cold 4 to go in r4c6, connected to a real 2.
This puzzle broke me 😑
111 minutes
@16:18, 0 is an even digit?🤨
Yeah, apparently.
On a number line, it's -2, -1, 0, 1, 2, etc...
0 falls on the even spacing (two away from -2 and 2).
Who knew..
(^^I had to rhyme lol) 😂
Personally, i think "0" has no value (but, on a "number line, it's even).
Hope that helps. 😂
@@stevesebzda570 well, turns out there's a whole Wikipedia article about it:
In mathematics, zero is an even number. In other words, its parity-the quality of an integer being even or odd-is even. This can be easily verified based on the definition of "even": it is an integer multiple of 2, specifically 0 × 2.
I think I got mixed up with 1 not being prime...
yes, it is even. a number is even if can be exactly divided by 2, i.e. gives a whole number upon division by 2. 0/2 = 0 and 0 is a whole number, so 0 is even.
Kansas City is on the Border of Missouri and Kansas. So it is and is not in Kansas.
28:30 sherlock holmes didnt actually say that, this line originally comes from star trek tng where mr data was dressed as sherlock
Renban won't have a weird plural; as a Japanese word, it won't have a plural at all.
18:09 i don't believe this works as the for cold and hot cells the value on the line and dot are different. there could be a cold 9 on the edge of the line with the black dot that only changes the value for kropki dots making it an 8-4 pair
nvm i read it wrong
