🟦 Even Sudoku

📖 How to play Even Sudoku

1. The sudoku rules apply: 1 through 9 with no repeats in each row, column, and 3x3 box.
2. In addition, the shaded squares (marked with a square) can only hold even numbers: 2, 4, 6, or 8.
3. Unshaded squares can hold any number. Each puzzle has a unique solution.

💡 Tip: there are only four even numbers (2, 4, 6, 8). If a region has four shaded squares, those exact four numbers must be split among them.

✏️ Notes mode: press the ✏️ button on the keypad (or the N key) to jot down candidates in the empty cells.
