Orange vs. Blue Boxing
- Killer cages
- Kropki dots
- Arrows
The brief
Normal Sudoku rules apply. ARROWS- Numbers on arrows sum to the number in the arrow's circle. All upper body arrows are 2 in length. Numbers may repeat on arrows, if other rules allow. Colors in circles have no effect on the puzzle. KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. KILLER CAGES- Numbers in cages sum to the number in the top left corner of the cage.
