Normal Sudoku rules apply. Additionally:
1. Standard arrows: Digits along an arrow in the grid must sum to the digit(s) in its circle. Two-digit circles are read from left to right or from top to bottom.
2. Standard killer cages: digits in cages must sum to the number in the top left corner of the cage.
3. Standard diagonal: the digits from 1-9 must appear once each on the marked main diagonal.
