Sandwiched Entropy
- Entropic lines
The brief
- Normal Sudoku rules apply.
- Entropy line: Any set of three consecutive digits on the orange line must contain a low (1, 2 or 3), a medium (4, 5 or 6) and a high digit (7, 8 or 9).
- Sandwich: Clues outside the grid indicate the sum of all digits between 3 and 6 in the respective row or column. For example, the row 123456789 would have the sandwich clue 9 as the sum of 4 and 5.
