Notes Mode: Tap the Pencil icon to toggle Notes. Use it to draft possible numbers in an empty cell.
Smart Clearing: When you place a correct number, the game will automatically erase that number from your pencil notes in the same row, column, and box!
Mistakes: You are allowed a maximum of 3 mistakes per puzzle. Be careful!
