Sandwiches and Sides
- Diagonals
The brief
- Normal Sudoku rules apply. Place the digits 1-9 in each row, column and box without repetition.
- Sandwich: The numbers outside the grid give the sum of the digits between the 1 and the 9 in that row or column.
- Outside: The digits in the numbers outside the grid must appear in one of the first three cells of the row or column as seen from that direction.
- Diagonal: Digits may not repeat along the marked diagonal.
