- AutoFill Mode - all notes will be automatically populated and then kept in sync with the numbers you enter. You can remove notes. You can add notes only if you previously removed them. In this mode the game does everything for you and lets you do the thinking. As in all Sudoku games with AutoFill mode enabled: it is just too easy to play level one and two, so use it only for higher levels.
You can switch back to manual mode - the auto-populated notes will remain.

- Manual Mode - you are responsible for adding/removing notes. No restrictions.

- Manual Mode with "smart notes" - you are responsible for adding/removing notes, but the game will auto cleanup the corresponding notes when you enter a new number.
If you change your mind and remove the number the game will put them back.
In manual mode you can use the "Clear Notes" button to clear all notes.

- Double tap shortcuts - very convenient for this type of big puzzle:
1. If you want to quickly remove a number you entered - just double-tap it
2. When there is only one note in a certain square - double tap it and the note will become the number
3. If a row, column or sub-square is populated with unique numbers and there is only one number left - double-tap the square - the remaining number will appear.

- Conflict alert - it will show you that you have entered a wrong number.
The feature works differently in AutoFill mode and manual mode: In manual mode it will alert you if you have a conflicted number on the same row, column or sub-square.
In AutoFill mode it is obvious from the notes which numbers can be entered, so in that case it will also alert you if you entered a wrong number.
If it looks like you have solved the puzzle, but nothing happens, enable conflict alert and switch to AutoFill mode to see what you have done wrong.

- Clear notes in manual mode feature will clear all notes

- Reset puzzle (located in the main menu) will allow you to reset the current puzzle and start over

- Hint - press the "Hint" button and one unknown number will be revealed

- Multi-Touch grid - you can touch the grid with up to five fingers and the rows/columns touch will be highlighted - mostly for fun, but you can use it to highlight more than one row and column and concentrate on the numbers

- Timer - game timer - you can turn it on and off from the main menu

- Sound - you can turn it on and off from the main menu
