Even-Odd Sudoku
Cells are shaded to show whether they must contain even (2,4,6,8) or odd (1,3,5,7,9) numbers.
Rules:
- Each row must contain 1-9 (no repeats)
- Each column must contain 1-9 (no repeats)
- Each 3×3 block must contain 1-9 (no repeats)
- NEW: Blue cells must contain even numbers (2, 4, 6, 8)
- NEW: Orange cells must contain odd numbers (1, 3, 5, 7, 9)
Even numbers (2,4,6,8)
Odd numbers (1,3,5,7,9)
Blue cells need even numbers, orange cells need odd numbers.
