FortresS-Cells
(Published on 23. July 2026, 22:20 by Scojo)
Rules:
- Place the digits 0-9 once each in every row, column, and 3x3 box. To achieve this, one cell in each row, column, and box must contain two digits.
- Schrödinger's Fortress: For any cell in the grid that contains two digits, one of the digits must be greater than all of the digits in orthogonally adjacent cells, and the other digit must be lower than all of the digits in orthogonally adjacent cells.
- Cages: Digits in a cage sum to the total in the top left corner of the cage.
Solve in SudokuPad
Solution code: The 10 digits in row 7 from left to right, with the lower digit first for the cell with two digits.
