81 digits: Soduku can be tough, but its rules are simple. Fill a nine-by-nine grid with digits, making sure no column or row has the same number twice. The grid is subdivided into three-by-three blocks, and these also can't repeat a number. The game starts you with a few prefilled squares, and the rest is up to you. In Sudoku Unlimited, tap a square to select it, and the app highlights its row and column for easy scanning.

Skin in the game: The game includes four skins, including this notepad design. All work the same: Tap a square to conjure the number pad. Tap the pencil icon to switch to "notes" mode and jot down tiny numbers to note the square's possible answers. (Here, 4 and 5 are noted as possibilities.) Tap the Auto-Fill icon, and the app does the dirty work for you, filling every empty square with notes of its possible numbers.
