Monkeys Attack Emerald City
- Killer cages
- Kropki dots
- XV and number dots
- Negative constraint
The brief
Normal Sudoku rules apply. Numbers in cages sum to the number in the top left corner of the cage. Numbers may not repeat in cages. Numbers with a V between them sum to 5. Numbers with a black dot between them are in a ratio of 2:1. ALL POSSIBLE V AND BLACK DOTS ARE GIVEN.
