** TODAY'S PUZZLE **
We had a really lovely email from Jakhob telling us about his friend (with whom he constructs puzzles) wooferzfg's birthday and requesting we take a look at Loop Nurikabe, a puzzle they are so proud of they made a fridge magnet of it!
This puzzle has a 100% rating but very few people have managed to solve it in nearly a year. (One of our testers spent HOURS on it and couldn't finish.) Simon decided to give it a go and started early this morning... it was a good job he didn't start later!!
Play the puzzle at the link below:
sudokupad.app/ay00mqlwli
Rules:
Every cell is either water or land. All water cells must be orthogonally connected, and no 2x2 area may be entirely water. Groups of orthogonally-connected land cells form islands, which do not touch orthogonally, but may touch diagonally. Draw a non-intersecting loop through the centres of some cells which passes through each island exactly once. The loop may only visit one cell in each island. If a clue is on a land cell, it indicates the size of its island. Every island must contain exactly one clue. If a clue is on a water cell then the loop must pass through that cell and the clue indicates how many water cells are visited by the loop between the previous island and the next island. Every water section of the loop must pass through exactly one clue. A '?' can represent any non-zero value.
Note that, to check whether you have the correct solution, either compare your solution to Simon's in the video (which is correct) or play the puzzle in Penpa at the link below (which has an inbuilt answer check function for loops!):

I just took an epic 2 1/2 hour journey on a ship. I thought I was promised a relaxing cruise visiting some islands but instead I was in constant awe of the mad genius captain that managed to navigate the toxic waterways using a nearly useless map with most of the information missing. Instead of visiting the islands, he crashed into the rocks 21 times, hitting every possible island and blaming the map each time but at least he only hit each one once!

29:00 Simon is going for this huge deduction why this can't work, while missing the first line of the rules: Water cells must be orthogonally connected. :D
@toms7114
@toms7114 2 месяца назад
This is only true if the loop must be an orthogonal loop and can not transit diagonally, which is not prohibited by the rules. The puzzle breaks if the loop is allowed diagonal traversal though, and as such the rules should be updated for clarity.
@crwall05
@crwall05 2 месяца назад
@@toms7114 The rule says "All water cells must be orthogonally connected". So what Simon was trying (9 as an island) would not work at all since it forces the 1 water cell to be isolated and keeps it from connecting to any other water orthogonally (regardless of whether the loop can move diagonally or not, which as you mention is not specified.)
@blahfasel2000
@blahfasel2000 2 месяца назад
@@crwall05 Yes, but without the "loop only moves orthogonally" restriction the loop could go diagonally from R8C9 to R7C10 (the "1" clue), which means R8C10 wouldn't have to be island and could serve as a way out for the water.
@359Aides
@359Aides 2 месяца назад
@@toms7114 while this is true, I'm pretty sure Simon went in with the assumption that the loop was orthogonal (at least in that line of deduction) and probably it was an oversight on the rules. With that in mind it was really a convoluted way of proving it when he could have seen the single isolated water cell he's drawn up in his coloring.
@acantilado

At 2:17:00, Simon decides tthe 4 can't be water, because in that case, the two lose ends of the loop would join having two distinct clues. However, I don't see at this point why the lower end couldn't turn left (to a cell that would be island, to avoid a 2x2) and not break. I'm sure there's something that later disproves that path, but I don't see Simon going through that logic at that moment. Is there anything obvious that I'm missing?

45:46 "how are we ever going to know whether that's an island?" If you're Simon, you're going to spend the next two hours solving the puzzle before you can figure it out. If you're a dirty cheater like I am you'll go "If this puzzle has a unique answer, you have to be able to disambiguate that cell. The only possible way to disambiguate that cell is if the island to the left has a numbered size. The only number it can reach is 13, so that island definitely connects to 13, which is also an island." I know puzzle creators don't usually intend for uniqueness to be part of the solution, but I just have too much fun using it whenever I can.

Crazy that I'm trying this. Making some progress when I realized that the way I'm doing it, the line would have to eventually pass by the outside of one of the 4 areas which is impossible because of the 2x2 water rule. Might have to restart taking more care. Edit: I think I figured it out. There is a clue at the top of the puzzle that could be a 1 sized island and let the loop pass twice. That will make the loop I'm seeing possible.

Water streams needing a clue before it can go on land. The implications of no 2x2 water blocks. How all cells with digits around an island must be water. And then you get stuck and you have to think about the overall path of the loop in each section. The puzzle just builds on each technique as you make progress. It's really incredible how it was able to accomplish this.

Fascinating puzzle (which I defenitely couldn't do on my own...) - but I have one question: where in the rules is exactly stated that the loop has to move orthogonally? "through the center of cells" can also be achieved by diagonal movement, can't it?
@pascal6871
@pascal6871 2 месяца назад
You are right, the rules don't say that. Standard loop rules do say orthogonal which is why Simon thankfully didn't consider it because the puzzle clearly wouldn't be solveable

This was a super fun puzzle! I'm still amazed about how powerful the question mark clues were. Haven't started the video yet, but I'm excited to see how long it takes for Simon to realize the loop must go in and out of the channel at the top of the grid. It seemed impossible to break into the puzzle before making that somewhat meta deduction :)

Normally I would not dare try a puzzle that is ranked 'very hard' and takes Simon over two hours to solve (taken by the lenght of the video). But as soon as the solve started, I realised that I might actually be able to do it. Somehow I find this much easier than Sudoku! Still took me three hours but I never felt that I got stuck. Thank you for this excellent and very enjoyable puzzle.

There's a geology joke that goes something like this. "A geologist was on a hike with a friend. He took the opportunity to explain the things that they were seeing saying things like 'look at that beautiful purple rock over there', 'the red rock formation you see is...' 'see those orange rocks?' And 'the white soil contains...'. His friend eventually turned to him fustrated 'I don't know what you're talking about, everything you pointed at was brown!'"

@noambbyp That's funny, I guess. But guess what I learned in science class (speaking of "geology")? (We were studying "rocks and minerals," "igneous rocks" being eing one of them-- one of three on the earth actually) Guess what the science teacher said? [I forget the percentage, so I'll paraphrase]: "The number one igneous rock found on earth is 'basalt'." "The earth is mostly 'basalt'" in other words. And "basalt" is grey/gray. ["Basalt" is the igneous rock used in macadam, roads, streets and paths, in case you didn't know] But, "Basalt" is everywhere! 😆

I was daunted at first, and I felt no shame doing this puzzle along with Simon, but it was incredibly fun all the same, and I did catch a few things before Simon did for which I was rather proud. :) It's the sort of hard puzzle where you can steadily make progress once you get the hang of it. I rather wish I had another puzzle of this same sort I could apply my skills too… Anyway, thank you so much, Simon!

@studgerbil9081
@studgerbil9081 2 месяца назад
Both Mark and Simon have stated that they run the puzzles though testers to ensure that a puzzle has a unique solution, but that they cannot use that knowledge alone to disambiguate a specific cell or group of cells; but they must use logic from the rules and clues to do so, the point being that if they cannot do that, then there can be no unique solution based on the rules and clues provided. They honestly have to go into every solve without the knowledge that the puzzle is unique. It's tough to do that. What helps we the viewers is that a puzzle without a unique solution based on the rules and clues will not be shown on this channel. It is a failed puzzle unless the setter specifically states that the puzzle has two solutions (I think I recall one that was specifically set that way).

A Simon video is never too long. It pleasurably postpones all the dreary chores (and work) I have to do, love the long ones. Amazing how much angst there is in the comments about the color choices. What cracked me up is that I am sure he has done puzzles in the past that used blue and green. The leopard can indeed change his shorts.

At 2:16:55, why does he say those loop segments must join? That situation can be proven wrong because there wouldn't be enough clues for islands or water segments, but Simon discards that alternative without those considerations

2:17:00 "And therefore that closes the loop". Why? Why does Simon conclude at that point that the 'bottom' piece of loop *must* continue upwards and not into the land he just put into R16C14?
@AnteroPedro
@AnteroPedro 23 дня назад
Because that cell would need to connect to the “?” clue that later proved to be water. And as the loop crosses there, it wouldn’t cross the land slightly upwars with the “?”. It wouldn’t have space to go up without crossing the (later) water “?” twice.

@RecreationalCynic
@RecreationalCynic 2 месяца назад
One idea for the solution checker is to have the solver put into the cells that the loop visits (that don't have numbers already) the lengths of the runs in water cells and the sizes of the islands in island cells; if a number is more than 9 use the ones digit. For example, a run of 12 water cells, followed by a 4-large island, followed by 3 water cells, followed by a 5-large island would have "2 2 2 2 2 2 2 2 2 2 2 2 4 3 3 3 5" in the cells on that part of the loop. Cells the loop doesn't visit are left blank. More formally: For each cell that the loop visits that is either blank or has a question mark (ie, no given digits): - if the cell is water put the length of that run of water cells - if the cell is land put the size of the island If the number is larger than 9 put only the ones digit
