Opposite Day
- Killer cages
- Kropki dots
- Whisper lines
The brief
Normal Sudoku rules apply. Numbers on green lines are at least 5 apart from their neighbors on the line. Numbers in cages sum to the number in the top left corner of the cage. Numbers with a white dot between them are consecutive. One of the numbers (from 1-9) appears in only one cage, in box 1. No other cages contain this number. There are no other negative constraints. Expect the unexpected.
