In what must be one of the greatest April Fool pranks ever - even if only a few people and Cracking The Cryptic viewers will appreciate it, Phistomefel released the puzzle Simon attempts in this video on 1 April 2022. Simon did not know it was released on April Fools Day when recording!!
You can play this remarkable puzzle which is called "♫ Slitherlink take me home ♫" here:
test.crackingthecryptic.com/s...
Rules:
Draw two closed loops in the grid - a Touching Slitherlink that runs along the edges, and a Country Road that runs from cell centre to cell centre. Neither of the two loops may touch or cross themselves. Not all grid points have to be traversed by the Slitherlink and not all cells have to be visited by the Country Road. Each number is either a Touching Slitherlink clue or a Country Road clue. Both at the same time is also possible. A Touching Slitherlink clue indicates how often the loop touches the edges of the cell containing the clue. The Slitherlink divides the grid into several regions to which the Country Road clues refer. A Country Road clue indicates the number of cells visited by the Country Road in that region. The Country Road passes through each such region exactly once. Cells not visited by the Country Road may be orthogonally adjacent only if they are in the same area. Each region can contain none, one or more Touching Slitherlink clue(s), and each region can contain none or one Country Road clue(s). If a region contains no Country Road clue, an arbitrary number (greater than 0) can be traversed by the Country Road.
In the video, Simon first attempts a Country Road puzzle by Eric Fox to remind himself of the rules of Country Road! You can play this puzzle here:
tinyurl.com/yzpwwppu
Rules:
Draw a non-intersecting loop through the centers of some cells which passes through each region exactly once. A number in a region represents how many cells in the region are visited by the loop. Orthogonally adjacent cells across a region border may not both be unused.

A bit late, but for people who did not understand the normal touching slitherlink rules either, "touched" means the following "A closed loop that does not touch or cross itself must be drawn along the dashed lines. The numbers indicate how many times the loop makes contact with the numbered cell. A contact occurs when the loop reaches one of the corners of the numbered cell, and it ends only when the loop leads away from such a corner. Within a contact, the loop may travel on one or even several of the edges of the numbered cell! " ~wikipedia

I was going to give up on the puzzle because I couldn't even understand the rules, so I started watching the video. After watching for a few minutes, I started to understand the rules a bit better. Once Simon joked about the slitherlink region wrapping around the entire grid, I paused at 21:16 and decided to try solving it again. Surprisingly, I actually managed to solve it. The logic about there only being two regions reeeeeally helped me.

At first I thought how would you even start this. Then as soon as Simon said that there are only two regions then I immediately jumped to “is the April fool that there are no CR clues?” But then he showed that there must be one CR clue and it was obvious to me that there could only be one because the other would have to be way bigger than 4. All that stuff in the rules about it being possible that a clue is both CR and TS is just misdirection.

@emilywilliams3237 2 года назад

I had to come over here to see this video, at least the start of it. I was not disappointed - Simon imitating John Denver (though with more articulation of his words ...). Excellent. And then I saw the grid, and I had already been alerted on the main channel that this is an April Fool - so clever to see the digits of 4-1-2022 in the grid! I will have to return at another point to watch the rest of the video, which I am very much looking forward to! (Edited ... but I think you are a complete genius ...)

@2Lazy2BAwesome 2 года назад

The way I thought about with disambiguating the 1s situation (53:00) is: whatever the correct slitherlink is, it should go either below, or above 1s, which means it can never go anywhere from the both top corners, i. e. 4 edges connected to top corners of those 1s are not parts of slitherlink. This gives you a lot of Xs and helps a lot with coloring inside/outside regions.

@HunterJE 2 года назад

I feel like Simon made the central gimmick harder than it needed to be with all the experimentation with the 4 clue and whatnot. Once you know that there are only two regions, you also know that at most two of the given clues can be CR clues. This means the TS has to visit all but at most two of the nonzero clues, which categorically rules out a very small loop. When you add to that the fact that one of the three clues in the top left is forced to be one of the CR clues, it becomes patently clear that any TS loop that reaches all but at most one of the remaining nonzero clues will definitely have a long enough border to rule out a ≤4 CR clue, which tells you the other region's CR total is unclued and rest of the clues are TS.

@LazerWulf 2 года назад

That may be intuitively obvious, and I feel like that is exactly the point Simon reached eventually, but the point of these videos is to "show your work", so to speak, so what Simon was doing was proving that point logically to himself (and to us) in order to get a clear grasp of the rules. And sometimes it's not intuitively obvious, in which case it does take some trial and error to figure out how it's supposed to work.

@avishevin1976 2 года назад

Can you explain how we know there could only be two regions? Simon read that into the rules, but I don't see where the rules force that conclusion.

@HunterJE 2 года назад

@@avishevin1976 The country road can visit each region can exactly once without leaving and re-entering, and since the regions are defined by which side of the slitherlink they are on the "out" regions cannot possibly border each other and can only border the "in" region. As such, having more than one "out" region would require the country road to exit and re-enter the central region to travel to every region, which would break the one-visit rule.

Here is one of my occasional revisiting of this video, and while the video is great, a good portion of this comment section saddens me. It's the classic "I don't understand it, therefore I do not like it and I will not try to understand it" fallacy. No one deserves that treatment.

@57thorns 2 года назад

One thing that might have sped up was. eg at 56:49 the cell above the blue (r2cc5) can't be orange because it would create a cul-de-sac. Remember that every_ orange ceel bordering a blue has a road in it. This colouring could have been done at many points.

@AFastidiousCuber 2 года назад

I want to try this puzzle, but I really do not understand how the Touching Slitherlink clues work. I feel like it should be obvious, but I must be interpreting them wrong because it doesn't make any sense. If the 4 is a Touching Slitherlink clue, doesn't this mean that all four edges of the cell should be part of the loop creating a 1 cell region?

@AhsimNreiziev 2 года назад

No, the Touching Slitherlink clues refer to the *points* of the square, not the edges. And besides, a loop around a cell would only touch the cell once, whereas what Simon showed in this video is how it touches the cell 4 times. Perhaps it would help to watch the other Touching Slitherlink puzzle by Phistomefel that Simon did, which can be found over on Patreon.

@msolec2000 2 года назад

Ashim is correct. You are thinking of regular slitherlink (and that's also why you never see a 4 in regular slitherlink)

@SjorsHoukes 2 года назад

HOORAY! First time I solved a Phistomefel puzzle faster than Simon! Took me under half an hour. That is after watching Simon’s intro and explanation of the rules mind you, and I used this video to make sure I wasn’t crazy. Reminds me a lot of the puzzles in The Witness, and I now realize why I also got most of those faster than Simon did. These kinds of puzzles are more easily solved by just trying out possible paths, and I think Simon is a bit averse to that tactic. He wants to make sure that all logic has been deduced and there are no other options. Especially clear in the last few cells of this puzzle, which took him way more reasoning than was strictly necessary. However, the explanations and logic are what make these videos so valuable, so I wouldn’t have it any other way. 💛

@e7diablo 2 года назад

Don't quite get how this is an April Fool's puzzle other than the rule-set being out there and complicated. It's perfectly solvable and has awesome Phistomofel-standard logic. Seems like a regular and genuine puzzle, just on the hard side of normal (which is probably the normal side of Phistomofel)

@donaldsnyder1543 2 года назад

I could be wrong but I think its the givens. 4's 2's & 1's for 4/1/2022

@onijester56 2 года назад

There are a handful of elements. First, the use of 4's and 1's and sufficient digits to have 2022, for "4/1/2022" (April First, April Fool's Day) to be formed from the given digits. Second, it's that there's only two regions in general. Having so many clues split up across the board suggests at least a few separate regions. And many people who might have attempted this without fully grasping the conceits of slitherlink and country road rules allowing there to be only two regions. Third, that the Rules specify that a clue could be (1) a Slitherlink clue, or (2) a Country Road clue, or (3) simultaneously a Slitherlink and Country Road clue. However, no clues meet the third criteria, this potentiality being a form of misdirection. I can see a lot of people getting stuck on figuring out if one of the clues is in fact both a Slitherlink clue and a Country Road clue. Fourth, that there's a Country Road "implicit blank" rule, allowing a region without a given Country Road clue to have any number of its cells containing the Country Road. Which connects with... Fifth, that there's only one actual Country Road clue at all. That is quite devious of Phistomefel, especially since 4 is a reasonable value to have for a Country Road clue and forces a tricky situation if taken as a Slitherlink clue. ---- Any one of these makes the puzzle feel like a prank at the solver's expense. All of them? Shakespeare's most acclaimed comedies might be said to lack such an interplay of jokes.

and don't the slithering rules imply that 4 cannot be a slithering clue? In the shape that Simon draws at 19:25 the slithering is not touching any of the edges. Or at least I think it's ambiguous if it does. Maybe that's how slitherings canonically work, but from how the rules are written, it's not clear, I think

@happy_srl 2 года назад

yeah, if touching a corner would count as touch the cell once, then the shape Simon draws shortly after with the 2 clue top left, would be 3 touches, not 2

@AhsimNreiziev 2 года назад

I think it helps to watch the other Touching Slitherlink puzzle by Phistomefel that Simon did, which can be found over on Patreon. In that video, the way Touching Slitherlink works (which is different from normal Slitherlink), is explained better. But essentially, a "touch" of a cell is the loop coming into any of the 4 corner points, staying along the edges for a while (could be no time at all, or as much as all 4 edges), and then leaving again. So ====== || | || 2 | || | ------------====== || || || with double lines being the loop segments and single lines being the edges of a cell, would be the loop touching the cell with the "2" twice (once in the bottom right corner, and once in the top left where it moves along 2 edges before leaving again), making the clue valid. Hope this helps.

@bentittl309 2 года назад

@@happy_srl I think the number of slitherlink touches is the number of different touches, not the number of sides/corners touched. The touch on the top left corner touches two sides, but is only one distinct touch. Then the bottom right corner of the cell is touch #2.

@happy_srl 2 года назад

@@AhsimNreiziev @Ahsim Nreiziev that does help for the 2 clue. It's not clear to me that that's what's meant by the rules, but it makes sense. The conclusion about the 0 clue is still wrong then though, because it's not "staying along the edges", if it just touches the top right corner of the cell

Does this puzzle have a unique solution? It seems easier to solve by just guessing and trying something and tweaking the edges until a solution is reached.

@Jaxom35x 2 года назад

If the 2's in the corners are touching clues, then isn't the 2 sides AND the corner touching making it 3?

@DuncanBooth 2 года назад

No, took me a while to understand that as well. The clue is the number of disjoint touches. So the two sides are a single connected touch and the corner is the other one. The 1 clues can be a single corner or one to three connected edges, the 4 clues have to be four corners.

@BlielPol 2 года назад

I don't get what happened here. In which way was this puzzle an April Fool's? Didn't it have a valid solution in the end?

@bobblebardsley 2 года назад

I think in the sense that Country Road puzzles would normally have far more regions than just two, one of which is only visited in a single cell. So with the lengthy set of rules, unless you spot that the Touching Slitherlink can only define two regions in total, you're probably looking to split the grid into 6-7 or more different regions. It's logically correct and valid but I guess if you do a lot of these kinds of puzzles, the solution is still pretty funny. (Also the clues were all from 1/4/2022 or 4/1/2022 depending which date format you use, so the starting grid itself is a reference to April 1st 2022.)

@Gnarlf 2 года назад

It does have a valid solution, yes. And it is beautifully constructed. So you could just see it as another brilliant puzzle. However there are some indicators, suggesting this to be meant as an April Fools puzzle. It was realeased on 01-04-2022. It containst a lot of ones and fours (and as someone more observant than me pointed out 2 0 2 2 as well). And it messes with your brain a lot. You wouldn't normaly expect a slitherlink forming that number of regions. You wouldn't normaly expect a country road to have such a tile ratio between the regions. And if you recall Simons AF-Puzzle for Mark was a 4x4 and Marks AF-Puzzle for Simon was "quite approachable". Still both had their valid solutions, but they were way harder than anyone expected them to be.

@MarushiaDark316 2 года назад

I'm not quite sure why there can't be more than two regions. Simon tried having the Slitherlink go on and off the border, but that looks plausible to me.

@avishevin1976 2 года назад

I didn't get that either. That is, I don't see how the rules preclude it.

@CaptianKatsura 2 года назад

The problem is that there is only a single Slitherlink that forms a closed loop. So no matter how it moves, it'll always end up creating an inside region and a number of disconnected outside regions. Since these outside regions don't touch each other and the country road must visit every region, the only way for the road to travel from one outside region to another is through the inside region. And that's where the issue arises. If there's more than one outside region, the country road will enter the inside region more than once (since even if there are only two outside regions, the loop has to close so once it leaves the first outside region it'll need to make it's way back eventually). So that's why there can only be two regions.

@MarushiaDark316 2 года назад

@@CaptianKatsura Ah, ok. It's because it can't reenter the middle region twice.

@battle00333 2 года назад

I somehow managed to solve it in 24:34 I figured out very quickly that the top left had a country road clue. and then operated on an assumption that there was a second clue until I remembered the constraint on empty cells. Which made me realize that, If One region only has a length of 2, then all other cells in that region are empty, and MUST be bordering a country-road on the other side of the slitherlink. The puzzle then essentially becomes a clueless yaijin puzzle, with the exception of 1 cell remaining empty, or as a "wall"
