Normal sudoku rules apply. On the indicated diagonal digits do not repeat. All clues outside the grid are both X-sum and Sandwich clues. An X-sum clue indicates the sum of the first X digits in the respective row or column where X is the first digit seen from the clue. A Sandwich clue indicates the sum of all digits between 1 and 9 in the respective row or column. Digits on an arrow sum to the digit in the circle from which the arrow emerges.
