📖 How to play Little Killer Sudoku

1. The sudoku rules apply: 1 through 9 with no repeats in each row, column, and 3x3 box.
2. Each outer arrow carries a number: it's the sum of every square on the diagonal it points along.
3. Note: numbers CAN repeat within a diagonal (the diagonal isn't a sudoku region, just a sum).
4. Each puzzle has a unique solution.

💡 Tip: start with the arrows for short diagonals (2 or 3 squares); they have very few possible combinations for their sum.
