Diffambiguate
- Kropki dots
The brief
- Normal sudoku rules apply.
- Digits separated by a black dot are in a 1:2 ratio (one is double the other.) Not all possible black dots are shown.
- It must be determined whether each grey line is a 'Same Difference' line or a 'Different Difference' line.
- SAME DIFFERENCE: Adjacent digits on a Same Difference line always differ by the same amount, but this 'difference value' may be different for different Same Difference lines.
- DIFFERENT DIFFERENCE: Every pair of adjacent digits on a Different Difference line must differ by a different amount. Eg: if there's a 3 next to a 5 on the line, there can't be a 7 next to a 9 anywhere on the same line.
- The digit in the turquoise diamond indicates how many Same Difference lines are in the grid.
- The digit in the peach diamond indicates how many Different Difference lines are in the grid.
