- Killer cages
- Whisper lines
- Lines of set digits
The brief
Normal Sudoku rules apply. The SUM of any 2 neighbors on BLUE lines is a PRIME NUMBER. The sum of any 2 neighbors on the ORANGE line is NOT A PRIME NUMBER. Numbers on the green line are at least 5 apart from their neighbors on the line. Numbers in the cage sum to the number in the top left corner of the cage. Thanks to Flycatcher for the idea of prime consecutive pair sum lines.
