(The keypad changes color to indicate whether you’re in notation or solve mode.) There’s also a dedicated erase button, as well as Undo and Redo buttons-the latter two unique to Sudoku Vol. To solve a cell, you tap the cell, then tap the solve button, then tap the desired number. To make notations in a cell, you tap the cell, then tap the notation button, and then tap (on the keypad) the possible values for the cell. You use this 9-digit keypad to enter notations and cell values. Finally, when all nine occurrences of a number have been entered, that number is grayed out on the onscreen keypad. A Hint button, which can be used three times for each puzzle, fills in a random unsolved cell. (You can turn off this feature if you don’t want it.) In addition, if you double-tap any given cell or solved cell, all other given and solved incidences of that cell’s number are highlighted this is useful for quickly seeing, for example, which regions still need the number 2.
For example, one of my favorite “helper” features is called Borders: when you tap on a cell, a gold outline (shown to the right) surrounds the selected cell’s host region and the row and column containing the cell, making it easier to determine which numbers that cell can and cannot contain.

I tend to agree, but I didn’t hold a lack symmetry against the candidates. Although not technically a requirement, many purists don’t consider non-symmetrical puzzles to be “true” Sudoku. Unfortunately, none of the better Sudoku games available for the iPhone and iPod touch exclusively use symmetrical puzzles-those in which the pre-filled boxes (called givens) in opposing regions mirror each other.

(For example, a couple Sudoku apps that didn’t make the cut satisfied most criteria, but their methods for making notations obscured other parts of the puzzle.) Offers good usability: easy-to-use input methods, clear controls, and readable graphics. (These markings are often called notations.) Provides a way to note (or “pencil in”) the possible values for each square as you solve a puzzle. Includes puzzles with only a single solution. (Some Sudoku variants break the standard 9-by-9 grid into non-square geometric areas, or use colors or images instead of numbers.)
