Sphinx and Pyramid of Giza
- Killer cages
- Kropki dots
- Whisper lines
The brief
Normal Sudou rules apply. DUTCH WHISPERS- Numbers on red lines are at least 4 apart from their neighbors on the line. Numbers may repeat on red lines, if other rules allow. KILLER CAGES- Numbers in cages sum to the number in the top left corner of the cage. KROPKI PAIR- Numbers with a black dot between them are in a ratio of 2:1. TAN OVALS (eyes, ears and mouth)- Numbers with a tan oval between them sum to an even number. The 11 is duplicated in its cage because the red line can obscure it in some formats.
