Rules: Normal sudoku rules apply.

Each clue outside the grid indicates, in no particular order, the sum of the even digits and the sum of the odd digits among the first X digits in the direction of the clue, where X is the first digit in that direction.

Example:

The clue on the left is "2 10" since among the first 3 digits from the left (3 2 and 7) the sum of the evens is 2 and the sum of the odds is 3+7=10. The clue on the right is "6 12" since among the first 4 digits from the right (4 5 8 and 1) the sum of the evens is 4+8=12 and the sum of the odds is 1+5=6.
