Where Are The Missing Digits?
- Killer cages
- Whisper lines
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
In a cage, digits must not repeat and must sum to the value in the corner, if given.
Adjacent digits on a green line must have a difference of at least 5.
Digits on a pink line must not repeat and must be a set of consecutive digits, but may appear in any order.
