Japanese Sum Cave Cipher #15: Doppelcipher
(Published on 3. October 2023, 18:10 by KNT)
-) Place numbers from 1 to 9 in the grid so that no number occurs more than once in any row or column.
-) Clues outside the grid indicate the sums of connected digits in that row or column.
-) Where clues are given, they are in the correct order and complete.
Narrow Cave:
-) All digits are orthogonally connected, and all orthogonally connected groups of empty cells touch the boundary.
-) No 2x2 area may be entirely digits.
-) All colored cells contain digits, and the digit placed indicates the number of cells seen in all orthogonal directions, where empty cells obstruct vision. All possible colored cells are given.
Doppelcipher:
-) There are two distinct mappings of the digits 0 to 9 to the letters A to J. Each given letter may refer to either mapping.
-) Tens digits are guaranteed to be nonzero.
