Schrödinger's "Rat": Sudoku Perfection (And Comedy!)

[@Enaronia]

@@averygaron994 Not necessarily. Could also be a pair with a large difference, like 0/17. (But I figured there would be a 0. This puzzle did have both types.)

[@martysears]

Hey there cupcake coveters! Was really looking forward to this one. Probably the hardest one in season 2 (next week’s is more approachable again) but this is also probably one of my favourites. I’ll be honest, I’ve never really liked Schrodinger puzzles, mainly because my brain finds it hard to deal with them and make deductions with them. Setting this puzzle helped me start to overcome that, and I feel I have a better understanding of them now. I knew since I started season 1 and started compiling my ‘ideas list’ that I just had tom have an episode called ‘Schrodinger’s Rat’ and that this type of nonsense would have no place in season 1. I also decided early that Schrodingers could combine very nicely with a ‘same difference line’ test constraint, which I definitely knew I wanted to include at some point, on account of me having invented that line :) So the broad concept of this puzzle has been simmering away in my mind for many months, but I didn’t actually start setting it til last month. When I did, it came together surprisingly quickly, because I already knew roughly how it would work - the long segments being found first, and then gradually becoming shorter as the remaining differences get larger and larger. And yes I simply HAD to include a difference of 0 and a difference greater than 10. By far the hardest part of setting this was the ending. I had boxes 1, 2, 3, 4, 5, 7 and 8 mostly done, and spent a couple of days fiddling with boxes 6 and 9, trying to get the most satisfying ending possible. It kept ending up with either a 0 difference OR a greater than 10 difference, but not both. But I reallllly wanted both, and kept plugging away until it started co-operating. In the end I was mega happy with the result. The only irksome thing was the deadly pattern with 5s and 7s that could not be disambiguated using blackcurrants. So I thought I would just be silly and let them be the only two places which use one-way doors in this one! Thanks again for the feature Simon, your solve was brilliant, you cottoned onto all the intended ways of thinking very quickly, I actually expected a much longer video for this, so I was impressed how quick you did it. My favourite part was where you boldly claimed it would be impossible to do a long tour round the grid with such ludicrously large differences left. I smiled in anticipation for the inevitable moment where you would have to retract that statement :D Thanks also to everyone who has left nice comments - they are always a joy to read!

[@davidrattner9]

More outstandingness from you Marty!!! Love reading about your insights to these puzzles! Very thankful and grateful for you for what you bring to this community and who you are.

[@markthompson2874]

The funny thing is I knew you'd have a difference of 0 in there but it was the last difference I figured out so it kept me honest in a few places where I had to eliminate it. If I hadn't realized that, I'd have probably cheated the puzzle by not honestly eliminating it.

[@hanzel5417]

This is the best one so far for me... very satisfying to complete it.... i hope we get more and more seasons of Finkz and his cupcake

I'm loving these puzzle so much, thanks Marty! This was good fun, and took me 41 minutes - I liked the difficulty level. I also enjoyed reading your comments above. Thanks again, and I'm looking forward to more :)

[@mscha]

Thanks again for a wonderful episode, Marty! I got stuck at the beginning for a long time, wondering if you could have a -1 difference in box 7 and a 1 difference in box 4. (That might just allow you to take a different path in box 4.) Only when I assumed that wouldn't be the case I could continue, and (eventually) figured out the 8-0-8 in box 5 and knew for sure we were dealing with absolute differences.

[@ErnoWindt]

As usual, beautiful logic that Simon's able to quickly do in his head. Happy that Simon did it faster than me, but he was unencumbered by the possibilities that a 6-cell 2-difference line could be 024686, or a 5-cell 3-difference line could be 03696/30369. Resolved itself quickly, but it was worth considering. :)

47:16 what an insane puzzle. I'm not one for cursing against setters but when I realised what the difference had to be in the first segment of Box 6 I found myself whispering "I hate you Marty." I hope this comes across as a complement because it totally is, I couldn't believe the levels of insanity we were reaching in this puzzle and I loved every second of it! Also shoutout to the website app, I was surprised to see it holding up perfectly with the Schrodinger concept, it accepted my centre pencil marked 2 digits as the correct answer to the puzzle, really satisfying!

[@darthrainbows]

Argh! I got burned by the 0 difference again! I even thought at the start of the puzzle, "0 is a valid difference on a 2-digit segment with a Schrödinger cell", and by the time I got to the end of the puzzle, it had completely flown out of my brain. Solved in 43:22, the last 5 minutes of which were me panicking over what I did wrong to get that state in box 6. All I had to do was pretend nothing was wrong, and I would have the "duh" moment. Finkz is awesome as usual. Absolutely love this series!

[@y_prime]

solved in 28:28 - quite insane in a good way. I realized pretty early on that a 2-cell segment could be satisfied with a difference of 0 or 10+, but I didn't realize that a 3-cell (or more!) could have a segment going up and down by using a schrodinger cell until I got stuck in box 5. had to take the time to re-check my deductions in the previous boxes, though luckily they didn't break or else this would've been a much longer solve

[@gingerscholar152]

[@chocolateboy300]

I finished in 109:48 minutes. The Schrödinger's cells really messed with my mind. I was happy at first, because I was soaring along and got the first three segments. I started to slow down, but I made my way slowly though the puzzle. I was a little distracted today and the Schrödinger's cells made my brain kind of hurt. Not a great combination. It took me way to long to see that the pathway was restricted in box 5 due to having all values available from the previous segments, especially the one in box 4. Seeing that finally allowed me to place a crucial Schrödinger's cell and I strolled into the finish. However, I thought I broke the puzzle in box 6 as I had an 8 leading to a Schrödinger's cell and I had used all other possibilities. Then I realized that the constructor is Marty, and of course it leads to itself. You almost tricked me, but I made it through, even though I had a subpar time. As usual, Marty's Rat Run is brilliant. Great Puzzle!

[@SpeedyBozar]

Has anybody else assumed entering a box for the second time would require the same difference as before? I solved the puzzle thinking it was flawed until I watched the video and realised it's a new unique value every time.

[@stevieinselby]

🍰 Finkzday Friday! 🐀 I needed the pointer to look at how long a sequence could be possible for differences greater than 1 to get started, but after allowing myself to get that hint, I was able to complete the puzzle in half an hour. And right at the start, I said to myself "If there isn't one segment that has a difference of zero, I'll eat my hat" ... thankfully I don't have to get one of those illusion cakes that _looks_ like a hat in order to eat it ... the joy of Marty's puzzles is that you _know_ what tricks he's going to pull on you (some of them at least) but it's still great fun finding out where they go! Not trying to blow my own trumpet 🎺 but I also premonitioned a segment that went A-B-A as well 😉

This was awesome! Watched the video after solving it myself. I love the fact that Simon isn't really twisted at all so he doesn't see your deviousness. My strategy with your puzzles is to try to figure out all the possible traps you might set. I wonder if there's a way to represent a cat chasing Finks through the maze. Maybe having one set of criteria the cat and another criteria for Finks and the paths can't cross. Or create some rule that shows where the cat can go and Finks has to avoid those areas. Then for season 4 we introduce a dog to limit the cat :)

[@martysears]

you're right that it is possible theoretically, and that Simon overlooked it. However these options are soon ruled out by sudoku. Eg: 9 can't go at the left-hand end of the sequence because of the 1/9 pair in box 7, looking up. The blackcurrant can only be 3 and 6, so it has to start 036, and so can only be 0369(12) or 0369(6)... 12 would need to be made with 4 and 8 (this ends up being the right answer), or 6 would need to be made using 2 and 4 (because a 5 below looks up). SO either way that schrodinger cell contains a 4, meaning the blackcurrant in the row can only be 1 and 2, meaning the schrodinger cell can't contain a 2 after all. It's a slightly tricky part, and there's probably a couple of other ways to disprove it too that I haven't thought of! The most important thing to me was that some progress can be made without even knowing if that is a a 6 or a 12 yet.

Fantastic puzzle as always, but I think the rules should have specified that consecutive cells on a segment must have the same *absolute value* of the difference.

22:44 I suppose Simon missed the possibility for the 0 - 3 - 6 - 9 - 6 (1+5) in the first box (and similar in others).

I'm a bit late to this one because of American Thanksgiving, but delighted to see more Finkz all the same!

13:20 "The zero makes no difference." Quite literally.

[@Vathorus]

At one moment during my solve I was fully convinced that in box 9 Finkz can either go through 7 or 68 and it doesn't matter for the solution - making her a true quantum rat in the superposition of paths😮 unfortunately later I remembered that difference of 7 is already used in box 5. But this got me thinking, I'd really love a quantum puzzle where path would be purposefully ambiguous but it wouldn't matter because it would lead to the same sudoku digits solution!

Tricksy - more than once I thought I'd broken it and had palpitations, and I still think I got away with some things at the start, but after the bumps it was more sedate. Thanks.

Incredibly fun solve! I only needed to look for help when i THOUGHT i was stuck, but I never actually was! Spoilers: I never would've thought of the 8-0-8 and the difference of zero on my own; both times I was convinced that I messed up.

IT TOOK ME AN HOUR 40 BUT I DID IT IM SO EXCITEDDDD

Simon: "I did notice the added challenge"... well not quite. You did do some assumptions that were incorrect (e.g. box 1 & 2 could've been 0,3,6,9,2+4 & 0,2,4,6,8,1+5). Truth be told I only saw these possibilities after I got stuck in box 5. Wonderful puzzle. Completely exceeds expectations even from a marty puzzle. Got bamboozled a bit more than I hoped for.
