📖 How to play Arrow Sudoku
- The sudoku rules apply: 1 through 9 with no repeats in each row, column, and 3x3 box.
- Each arrow starts from a circle. The number in the circle must equal the sum of the digits in the squares the arrow passes through.
- Note: digits CAN repeat along an arrow (it's not a sudoku region, just a sum).
- Each puzzle has a unique solution.
💡 Tip: if an arrow has 2 squares and its circle is 3, it can only be 1+2. The lower or higher the circle's value, the fewer combinations there are.
✏️ Notes mode: press the ✏️ button on the keypad (or the N key) to jot down candidates in the empty cells.
