Dark Against the Light Side
- Killer cages
- Kropki dots
- Renban lines
- Negative constraint
The brief
Normal Sudoku rules apply. Numbers on Gray (Darth Vader) and Brown (Obiwan Kenobi) lines are each a set of non-repeating, consecutive numbers, in any order. Numbers on the red line (Vader's Saber) sum to the same number as the sum of the numbers on the blue line (Obiwan's Saber). Numbers on the blue and red lines may repeat, if other rules allow. Numbers with a black dot between them are in a ratio of 2:1. Numbers with a white dot between them are consecutive. All possible black dots on the Dark Side (columns 1-4) and all white dots on the Light Side (columns 6-9) are shown. Numbers in cages sum to the number in the top left corner of the cage.
