The Crusts Are Just The Beginning
- Arrows
- Whisper lines
- Renban lines
- Little killers
The brief
- Normal Sudoku rules apply. Place the digits 1-9 in each row, column and box without repetition.
- Sandwich Variant: Clues outside the grid are sandwich clues with a twist: in the appropriate row or column, digits between the 1 and the 9 must sum to the value of the clue. In addition, for each diagonal from the clue (of length at least 2), the digits between the first instance of each of 9 and 1 (as seen from the clue) must sum to the value of the clue.
- Dutch Whisper Lines (orange): Adjacent digits along a Dutch Whisper Line must have a difference of at least 4.
- Renban Lines (purple): Digits along a Renban Line must be a non-repeating set of consecutive digits, in any order.
- Arrows: Digits along a thin grey arrow must sum to the digit in the attached circle.
