** TODAY'S PUZZLE **
We have been alerted of a potential sudoku catastrophe. We've never featured a puzzle from by the constructor Meggen033 and it's something that some of you know we need to put right! So tonight we're trying their One-Fog-Nine sudoku - a 159 puzzle mixed with a little dose of fog! And it's a really nice debut (and fairly approachable we'd say!).
Play the puzzle at the link below:
sudokupad.app/wyqe8cjb01
Rules:
Normal sudoku rules apply. Each digit in column 1 indexes the 1 in its row (eg if R3C1=4 then 1 must appear in the fourth column of that row ie R3C4=1). The same rule applies to column 5 digits indexing 5 in its row, and column 9 digits indexing 9 in its row. The digits in a cage must sum to the small clue in the cage’s top left corner. Digits may not repeat within a cage. A black dot between cells indicates cell values with a 2:1 ratio (ie one digit is double the other). ALL BLACK DOTS ARE SHOWN. The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
Jane Street's Bug Bytes puzzle is available here:

(Simon's solve of this puzzle is on Patreon.)

19:00 "It's only easy because I have done loads of 159-puzzles before..." says Simon only to proceed putting in a 79-pair in the bottom row right after a three in the corner, forgetting that the three indexes the nine. But again, that's why I love Simon. Way too genius to spot the obvious.

@CrazyIvanTR Месяц назад

Doesn't index the 3 to solve the 79 pairs then doesn't index the 2 as well to solve the same 79 pairs, claims the 9 in column 5 was probably available for ages where it was just seconds ago. At this point I'm convinced Simon's brain is just like an adrenaline junkie but it finds its adrenaline from solving the hard parts of the puzzle, so it doesn't let him do the easy things unless he does the hard ones first. 🤣🤣🤣

@RecreationalCynic Месяц назад

Solved it in 23:55. I enjoy FOW puzzles since they focus you on where you need to look, but they're usually a slow advance since you're more often than not placing digits just at the edge of the visible area and clearing only a couple fog cells at a time. Indexing puzzles and other rules that let you place digits at a distance are a nice treat since you're able to locate a digit in the middle of the fog and clear 6+ cells at once (like the 4 in Col 9 at 18:44).

I'm used to negative constraints, but the rules here saying "shown" SO LOUDLY is making me second guess if it means 'shown *from the start*' or if more could be under fog.

@stevenape377 Месяц назад

A fantastic solve, Simon. You went through the logic so smoothly, and never truly got stuck. Side note, I don't quite understand why some people are so amused by you not spotting sudoku stuff when you're not even stuck. Surely, it's normal that people spot things in different orders. I imagine if you run a channel like this, you want to get the logic of the puzzle across, so you have incentive to prioritise the more complicated deductions over the mundane ones, to make sure you don't miss any. You do this extremely well imho. I still remember Clover's delight about this in her setter video. Thanks!

@dicebar_ Месяц назад

In programming, the technical term for the "möbius strippie loop" is recursion. Or you could call the reference "recursive". When dealing with recursion in programming, recursion is either causing a bug in the form of an infinite loop, or recursion is used intentionally where a piece of code references itself but comes with an end point. An example would be code that generates a Fibonacci sequence up to N numbers long.

@congobongoproductions5476 Месяц назад

I had a lot of problems with this puzzle because I felt the Low Mid High set theory had to apply everywhere but didn't know if it was a baseless deduction... also there's the fact that not only the columns 1, 5 and 9 index their number in the row, it's that EVERY column indexes its digit in the row (don't know if that's by nature of 159 puzzles in general or if that was the setter's intention but I wanted to point it out). Had a really good time resolving either way

If I were to venture a guess, I'd assume that the reason some people aren't as keen on fog of war puzzles is that they very easily become very linear experiences where the fog obfuscates everything but exactly the one clue that you need to proceed. Granted, genius puzzle design can create pretty much the same result even without fog of war, but there's always, at the very least, an illusion of being able to tug at different strings or being able to apply some advanced logic that the constructor may not have intended, etc.

@MattYDdraig Месяц назад

This was very lovely, a fun puzzle, and a good solve. I am coming to this a day late because of having been traveling, and between when you solve this puzzle and when I did just now there have been more than 8,000 solves. No doubt this is due to the exposure that sudoku puzzles get from being featured on CtC. I hope that everyone clicked the little heart, as I did, because it was good puzzle. I noticed that it has roping, and I think I recall there being roping in other 1-5-9 puzzles I have done. Is it an inevitable result of the indexing constraints? Or was it built into this puzzle with the use of the black dot relationships? Regardless, I did not "use" it to solve, but it definitely was there, almost as confirmatory as the removal of fog that I was on the right track. Thank you, Simon.

@Ghi102 16 дней назад

Unfortunately, I'm not a big fan of these puzzles because you can see that each horizontal group in a 3x3 always has the same digits. So, once you figure it out, every time you get a digit, you can always make a pair horizontally. Kind of ruins the puzzle rules when I start noticing that. In this case, I think the black dot negative constraint is doing that (or maybe the 1-5-9, I would need to verify)

He's a very smart man, but it seems his RAM is quite small and singing the song takes all of it.

A fitting debut from Meggen, a fairly easy 10 minute solve, although I'm still not entirely sure what the catastrophe that was averted was. Hint ... this puzzle is a lot easier when you remember to use the negative constraint on the black dot! The 1-2-3 "chocolate teapot" you put into box 6 were resolved from the get-go by virtue of the 3 having to play gooseberry between then 1 and 2.

The catastrophe would have been this setter never getting a feature 🙂

Thank you Simon and Meggen033! What a nice puzzle!!! Only 2 questions if anyone can answer for puzzles with indexes in columns 1,5 and 9. First, the "entropic phenomenon" that it is discribed by Simon at the start of the solution is applicable in all columns of the puzzle? Second, in sucl a puzzle, do we have always roping in all rows of the puzzle?

23:23, did it in little bits while at work, not sure if it slowed me down having to realign myself or sped me up by letting me think about the next step, I'll call it even.

@SamAHill Месяц назад

Finished in 27:38; only needed Simon's help to remind me when I got to the first 4-5 domino, and I had forgotten that the 5s and 9s are indexed too. :D

Simon is a Supertramp fan. He always takes the long way to solve! 😂

@sagov9 Месяц назад

another one of those 159 puzzles where the indexing actually applies to every column/digit, not just 159. Is that coincidental or is it somehow a feature of 159 puzzles?

@longwaytotipperary Месяц назад

I just noticed that after someone else pointed it out!!

@lionelleroux1132 Месяц назад

Once you notice the roping effect of "123" "456" "789" sequences you can fill the puzzle almost instantly but i couldn't find a logical explaination for this. I feel like I've already seen this property on other indexing puzzle. Is it a property / secret of those kinds or simple coincidence ?

Finished in 15:47. A lovely fog of war puzzle as always.

25:08. Great puzzle and i didn’t even have to do the entropic logic. Just Normal sudoku and indexing logic

@maljamin Месяц назад

I'm noticing that every column (not just 1,5,9) indexes its digit. Surely there was a reason? Wish I could've used it.

@jurgenbaumann67 Месяц назад

22:30 Your is faster than mine, I needed totally an hour for the whole sudoku. And the indexing numbers were confusing me. But I waited long time for you see your "3 in the corner" is an indexing 3. Maybe just cause i solved the sudoku before I watched the video.

@Sam_on_YouTube Месяц назад

12:44 Maybe my fastest time compared to the community here. Once I noticed the striping, I filled the whole thing out very quickly.

@AllenMS828 Месяц назад

Is this the ropiest puzzle ever? Not only was there complete roping throughout, it was the same sets of numbers in each row, and the pieces of rope were consistently placed in each horizontal set of three boxes. I guess you could call it ent-ropey. 😆

@klassenlm Месяц назад

Also in the columns we have entropic repetition

@ninjamunk Месяц назад

Well, a 159 index is by definition an entropy puzzle. As columns 1, 5 and 9 must have entropic repitition. Also: "it was the same sets of numbers in each row" I think you will find this in every single sudoku ;)

@AllenMS828 Месяц назад

@@ninjamunkLOL, yes, that's true about the rows in every puzzle. But what I meant was the position of each piece of each row was consistent. Like the first three boxes have the 456 piece in rows one, three, and two, and the same is true for the middle three boxes and the lower three boxes. Usually with roping, the positions end up shifting around more from box to box. I just thought it was neat that there were so many consistent elements to the solution. 🙂

@BrianZier Месяц назад

As someone else pointed out in a reply on another comment, the columns also fully indexed the digit positions. It was not just the 1-5-9 columns

@AllenMS828 Месяц назад

@@BrianZier Yeah, that was a really cool aspect too!

50:58@#7439, with a little help from the video to get started. I just could not quite recognize the break-in by myself. Once I got going, though, the rest of it turned out to be relatively straightforward.
