Boxing Day
- Killer cages
- Kropki dots
The brief
Normal Sudoku rules apply. KILLER- Numbers inside cages sum to 10. KROPKI DOTS- Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. FOR NEIGHBORS ON THE GRAY LINES, ALL POSSIBLE 10 CAGES AND DOTS ARE GIVEN. When a white AND black dot can both exist in the same place, the black dot is shown. For any cells not neighbors on gray lines, there is no negative constraint for cages and dots.
