Powercut [S-cell, Renban, RSL]
(Eingestellt am 30. Juni 2023, 23:48 Uhr von Christounet)
This puzzle is a special tribute to my father-in-law, who passed away a few weeks ago. He was the most skilled man with his hands, very fond of do-it-yourself, had built his own house and helped me build mine, knew and taught me countless tricks in woodworking, plumbing, welding, electricity... He was not the kind who would sit behind a desk or in his couch doing puzzles, and I don't think he ever ventured further than the easy-classic-sudoku-with-morning-coffee of his newspaper, but I think he would still have appreciated the looks and dynamics of this circuit-board grid. This is for you, Jean, you cut the power way too early...
Now about this puzzle, 4 linked grids with digits from 1-9 that have to be discovered by the solver. Each grid has its own internal logic, but they all need infos from others grids for resolution. I'm really proud and happy with how it turned out. It could be quite a long solve. But I hope and think it should be very satisfying to see it all come together. Only the lines are bifurcating here, not the logic ! I will put a walkthrough of the main intended steps in a hidden comment if you're interested.
Thanks to lerroyy and Paquet Voleur for testing it !
Rules :
- Normalish sudoku rules apply : in each 6x6 grid, place exactly 7 of the digits 1-9 (not necessarily the same 7 digits in all grids), so that each of those digits appear once in each row, column and box. To allow this, there is an S-cell in each row, colum and box, that contains 2 digits. Do the same in the 4x4 grid with 5 digits from 1-9.
- On renbans and region sum lines, the value of an S-cell is the sum of its 2 digits.
- Grey areas outside those grids do not contain digits.
- The switch (dashed yellow square) is part of the big renban going around the grid. It must contain one digit from 1-9. It is not a S-cell.
- Renban : Each red line is a renban and must contain a set of non repeating consecutive integer values in any order (e.g : 12-9-10-8-11). Digits can repeat on the lines if allowed by other rules (e.g : 7-8-27-6-28).
- Note that 2 separate renbans cross between the 2 left grids. Renban 1 : R6C2 -> R1C3. Renban 2 : R6C4 -> R1C2.
- Region sum lines : Blue lines must have an equal sum N within each region they pass through. If a line re-enters a region, each segment sums to N separately.
I recommend solving with Penpa, because it has answer check on S-cells too, and the pencilmarks show better on the lines.
Enjoy ! And consider giving feedback if you appreciate the puzzle !

Brilliant, just brilliant. I have a lot of trouble with mean mini puzzles, but this one is so masterfully set that it's a joy to solve the whole way through.

Fantastic puzzle! The region sum line in row 4 of the bottom right grid was amazing.

I was hesitant to try and tackle this monster but glad I did! The interactions between the different grids were interesting and unique. The bottom right grid probably gave me the most trouble, but it was difficult to decide where to focus during the mid-game so I might have strayed from the intended beta there.

@giladooshlon : Glad you put down the beast :) About the intended path, the bottom right grid was supposed to come quite late in the solve as you can read in the walkthrough in the hidden comment. So, yeah, if you tried solving that grid earlier, I guess it must have felt harder than intended !

Precision in the rules. Thanks @marcmees.

Q: do all 6x6 grids contain the same selection of 7 digits?
---
@marcmees : Not necessarily. My rules are indeed not clear enough about that, I'll make the precision. Thanks !

Thanks Christounet for another great S-cells puzzle! Beautiful solving path, full of surprises, and a very nice tribute to your father-in-law, who may not have been a sudoku aficionado but who was nevertheless skilled at other types of complicated chaos-ordering tasks, and a very generous one also. My condolences.
