Chaos Meidjudokuluk
(Published on 14. October 2023, 07:19 by tesseralis)
This puzzle a tribute to Chaos FilloSudokumino and Chaos CaveSudoku by Magnus Josefsson, and the fantastic Meidjuluk II by glum_hippo.
Place some digits in the grid and divide the grid into regions such that:
- There is a 9x9 subgrid filled with digits that forms a valid standard sudoku.
- Disregarding the interior 7x7 of the sudoku subgrid, the rest of the grid forms a valid meidjuluk (N=26).
Standard Meidjuluk Rules
Divide the grid into N regions (N=26), one of each size 1 to N. A region may not contain repeated numbers, and it may only contain factors of its size (e.g. a region of size 6 may contain any combination of 1, 2, 3, and 6, including none of them).
An example grid using a 6x6 embedded sudoku with N=17:
Solve online on Penpa. (For answer check, fill in the sudoku grid and the region borders of the Meidjuluk in green).
Full Puzzle:
Solution code: For Column 3 and Column 18 of the Meidjuluk grid, write the number of cells between region borders. (For Column 3 of the example grid, this would be 22414). Then, Row 4 of the sudoku grid.

Absurdly beautiful. Such an insanely impressive construction, to be able to resolve all this with so few clues. Not sure 100% does it justice.

It did take me a very long time to prove some aspects at the beginning, but it was worth the effort! It also took me far too long to DISprove some smaller things in the mid-solve, but I blame that on my own severe limitations in counting. I'm just very glad to have vaniquished this beast.

Fantastic puzzle that took me a well spent eternity! I had the solution and did not understand why the solution code was wrong, but as happens too often, I misread the instructions and forgot row 4 of the sudoku grid. Sorry for bothering you with my question and thank you

Wow...it took me two or three days in the afternoon and evening to finally complete the remaining 2/3 of this puzzle this afternoon...
Its difficulty can definitely be ranked among the top puzzles I have completed independently...
(Btw, in the comment on the last puzzle I completed, I said something like *I want to have a good rest*. But obviously I didn't do that...)

Congratulations for completing the puzzle. I hope it was afternoons well spent! Hope you have some time to rest for real now :)

That was absolutely magical! It's an extremely tough nut to break into at first, but it absolutely earns the right to be. Every step is satisfying, reasonable, interesting, and beautiful! The way things resolve is ridiculous fun to unfold.
I rarely say something might be the best puzzle I've ever solved - this is one of those puzzles. In my top 3 for sure. Pure serotonin.

Enjoyed testing this puzzle - especially since I got a few glimpses behind the curtains as the initial versions didn't completely work. The fixes revealed the logic of the construction, which is even cooler than what a regular solver would perceive.

thank you so much henry! I'm glad you were able to enjoy it. also, did you mean to log your solve ase well? ~tess

Everything about this puzzle is really cleverly/carefully plotted and fun to work through ! A very hard and very long solve for me, but worth every minute I spent, even on the earlier version I tested. I hope a lot of people try it despite the intimidating looks of the grid, because I'm sure they'll feel very satisfied if/when they complete their solve. Thanks again for this beauty :)

thank you chris ^_^ your feedback throughout was instrumental and this puzzle wouldn't have come out as it did without you and the other testers! ~tess
