RULES: Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and 3x3 outlined box.
If the sum of digits in orthogonally adjacent cells is 10, then they are separated by an X. If the sum of digits in orthogonally adjacent cells is 5, then they are separated by a V. All possible Xs & Vs are marked.
