How to Play Noos Sudoku

Fill the grid so every row, column, and bold box contains each number exactly once.
Standard: Uses numbers 1–9 in a 9x9 grid.
Mini: Uses numbers 1–6 in a 6x6 grid. Perfect for a quick mental reset.
Sudoku X: The two main diagonals (marked by a subtle highlight) must also contain each number exactly once.
Hyper Sudoku: Features 4 extra shaded inner 3x3 regions that must also contain numbers 1–9 uniquely.
Maxi (12x12): Uses digits 1–9 plus values A, B, and C in 3x4 rectangular blocks.
Mega (16x16): The ultimate test. Uses digits 1–9 plus values A to G in giant 4x4 blocks.
Use the 'Notes' mode to pencil in possibilities if you get stuck.
