Sneaking around
- Killer cages
- Kropki dots
- Whisper lines
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Digits in cages sum to the number in the upper left corner of the cage.
Digits in cells separated by a white dot must be consecutive. Not all possible dots are given.
The green lines are whispers lines: digits in consecutive cells along the line must differ by at least 5.
