The brief
- Normal Sudoku rules apply.
- Enter correct digits to uncover the fog. No guessing is necessary (or allowed!)
- Digits in a cage don't repeat, and must sum to the small clue shown in the top left corner.
- Adjacent digits along a green line must have a difference of at least 5.
- Digits along a yellow line form a palindrome... ie; they read the same in both directions.
- Digits along a red line alternate between odd and even.
- Purple lines contain a set of consecutive, non-repeating digits in any order.
- Lines never branch, cross or join to each other, or go diagonally.
- The digit in a coloured diamond indicates how many lines of that colour are in the grid.
- The digit in a grey diamond indicates how many cages are in the grid.
