Emerald
- Killer cages
- Kropki dots

The brief
Normal Sudoku rules apply. Numbers on green lines are at least 5 apart from their neighbors on the line. Numbers may repeat on lines. Numbers in cages sum to the number in the top left corner of the cage. Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given.
