Proper Boundaries Revisited
- Killer cages
- Kropki dots
The brief
Normal Sudoku rules apply.
ODD(+)- Numbers on blue and orange lines are ODD, and DO NOT REPEAT on each line.
KILLER CAGES(+)- Numbers in cages sum to the number in the top left corner of the cage. The 8 and 12 are duplicated in their cage because the orange line can obscure them in some puzzle formats. The TWO pink cells bordering the long ends of each cage also sum to the number in the top left corner of the cage.
KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given.
