Same Difference
The brief
- Normal sudoku rules apply
- Turquoise lines are 'Same Difference' lines. Each pair of adjacent digits on one of these lines has the same difference. However, this 'difference value' may be different for different lines.
- A digit in an orange diamond indicates how many lines have a difference value equal to that diamond digit. Eg: a 3 in a diamond indicates that there are 3 lines whose adjacent digits differ by 3.
