Rules:

Normal irregular 7x7 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 7. Digits on a grey line form a palindrome, i.e. they read the same forward and backward. On the marked diagonals digits do not repeat. Digits in a cage do not repeat and sum to the clue in the top left..
