Japanese Sums and Cages - Large (12x12)
(Published on 31. July 2026, 14:23 by Rätselmann)
Normal rules for Japanese Sums apply
Each number is the sum of a consecutive block of white cells.
Multiple numbers in a row/column describe multiple blocks in exactly that order.
Blocks are separated by at least one black cell.
Block lengths are unknown; only the sums and their order are given.
Allowed digits in this puzzle: 1–9, with no digit repeated in any row/column.
Dashed cages: The small number is the sum of all digits in the cage; black cells count as 0. No digit may repeat within a cage.
Silver cages (marked with an “S”): Their sum is not given, but ALL silver cages have the same hidden sum.
? represents an unknown one-digit sum, while ?? represents an unknown two-digit sum.
No Penpa and no SudokuPad … this is physically painful for me, sorry.
Solution code: Third row from left to right please, shaded cells as "0" (zero)

Sehr hübsches Zusammenspiel der Käfigsummen und der Japanischen Summenhinweise. Und sehr schwierig. Tolles Rätsel!

Ich habe vorgestern die 9x9 Variante gemacht und bin schon gespannt auf diesen Teil! :)
Könntest du noch den Tag „Japanische Summen“ hinzufügen? Dann finden es wahrscheinlich mehr Leute.
Joachim: habe ich gemacht, danke dir!!!

Großartige Konstruktion! Ich hab lange gebraucht, um die Stellen zu finden, die mich voranbringen. Und dann die Stellen, die mich wirklich voranbringen...
Danke dir!!!
Ich gebe mir auch tagelang Mühe, wirklich lösbare und dennoch knifflige Rätsel zu erstellen…oft nicht soooo einfach es zu bewerkstelligen, nochmals danke!

I can't get this to work out logically. Are all of the question mark clues correct? Particularly column 10?
Yes, everything is correct! It even has more clues than necessary, some of the silver cages are redundant. The question marks are all correct.
You were able to solve a part of it? If you can send me a screenshot where you are stuck, I will try to help out…joshi1004@gmail.com
