[@Neptune0404]

I love how this whole video beautifully parallels the ideal mystery story's peaks and valleys: At first the mystery seems unsolvable, but after some digging a clue is uncovered. The clue leads to the understanding of the framework, making it clear that there are connections, and a logic, but not too many definitive answers are revealed right away. Then there is a prolonged period of uncovering connections without reveling many clear answers before we finally get a breakthrough. One of the connections led to an answer, and now the road forwards seems clear. Several answers are revealed and for some time it seems as if the mystery is solved, but then another wall is hit, and the slow final grind begins. The answer is close but not yet solved and the final pieces must be put together, and after the last bit of effort the final question is cleared up, and the mystery is solved (there is even an "oh no" moment at the very end where we fear the whole case might fall apart, but it turns out to be a red herring). A wonderful video, not something I would normally click on but a friend recommended it and I'm glad I listened because it was a joy to witness.

[@fries6402]

For those wondering why at 9:30 we can deduce the center square (square 5) in box 5 to be pink, it’s because squares 5 and 8 in box 2 MUST be equal to squares 1 and 4 of box 5, since the cage that contains 1/4 in box 5 has all 9 digits and both by sudoku and box constraints, values in squares 1/4 MUST go somewhere in box 2 and the only space would be in squares 5/8. thus, the center square is the only place that makes sense- this line of logic is also repeated around the middle of the video as well. hope this helps!

It takes me an hour to do an easy sudoku so I am truly baffled as to how you managed this so quickly. And the fact you kept apologising for how long you were taking had me laughing as I’d have taken five years. Brilliant stuff!

[@3-headedmonkey27]

For people who are not sure about the first couple of deductions, it's easier to see if you start from the central box (Box 5). The centre square, put any number there, say A The only place to put that number in Box 2 is the bottom-right cell, because all but two of the other cells are in the same cage, and the other two (middle and bottom-middle) are in the same column (the two directly above). So bottom-right of Box 2 has to also be an A. Now look at Box 3, the only place to put A is the centre of the box, as all of the other cells are in the same cage as the second A, except for the bottom-middle and bottom right, but they are in the same row as the second A, therefore the centre square is also an A. The fact that that cage only has 8 numbers in it whereas the first cage we looked at has 9 is not relevant here, the logic works regardless.

[@iDanteownz]

I made this puzzle! It should actually be possible to use the same logic to generate a solvable puzzle with no given digits. You still need something to break the x -> 10 - x symmetry that nonconsecutive puzzles have, so I was hoping to use a single inequality somewhere on the board to do so. I still think it's possible to do this, but I was unable to construct such a puzzle with a logical solve path. My other puzzles are on LMG: logic-masters.de/Raetselportal/Benutzer/eingestellt.php?name=spxtr

[@QWDreaming]

Maybe a single greater-than sign from r1c1 to either adjacent cell?

[@iDanteownz]

@@QWDreaming That's the idea, but the problem is that for this arrangement of cages the 1s and 2s can be swapped. You can see this easily if you look at the finished grid and note that none of the 1s are adjacent to a 3. Thus, the puzzle would have 2 solutions :(

[@QWDreaming]

@@iDanteownz Ah OK, I see - and I appreciate your frustration! FWIW, a single digit is a very fair price to pay for a devastatingly simple ruleset and a simply stunning puzzle!

[@epic8088]

I was able to solve this puzzle using pattern recognition. It's similar to Knights constraints, but in C7,8,9 you threw me for a loop because the 9 and the 7 in those columns switched places. Good job if your point was to make me take the bait, lol. If it was unintentional, still good job 👍
