Balanced QuattroQuadri Sandwich Sudoku
(Published on 21. November 2024, 04:35 by Nell Gwyn)
- Balanced QuattroQuadri: Place a number from -4 to 4 in every cell such that numbers do not repeat within a row or column, and each of the four marked 3x3 boxes contains all nine numbers (from -4 to 4) once each.
- Sandwich: The highest and lowest numbers in each row and column form the crusts of a sandwich. Clues outside the grid show the sum of the digits within that sandwich in the indicated row or column (e.g. a row of 2, -3, 1, -2, 4, 0 would have a sandwich clue of -1).
