NOTE: Solving times of advanced Sudoku players. Your times may very and will get better with the number of puzzles you solve.
As in all Sudoku games with AutoFill notes mode enabled - it is just too easy to play level 1, so use it for higher levels.
Double-tap/Enter key shortcuts reduce the solving time by 10 - 20%.
• 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. 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.
• Wrong Number alert - When the entered number doesn't match the real number it will be colored in red and you will hear an alert sound.
• Conflicts Alert - When the entered number conflicts with another number on the same row, column or box it will be colored in red and you will hear an alert sound. Hidden conflicts warning.
• Clear notes - in manual mode clears all notes
• Hide/Show Notes - temporary hide the notes
• Hint - press the "Hint" button to reveal one unknown number
DOUBLE-CLICK/ENETER KEY SHORTCUTS - very convenient for this type of big puzzle:
1. If you want to quickly remove a number you entered - just double-click it or select it and press Enter
2. When there is only one note in a certain square - double-click it(or press Enter) - 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-click the square (or press Enter) - the remaining number will appear
Double-click/Enter Key shortcuts reduce the solving time by 10 - 20%.
When nothing is selected click a number in the notes pad or in the number pad
All squares containing this note or this number will be highlighted;
This feature will allow you to solve the puzzle much faster: 40% in AutoFill mode and 10% in Manual mode.
For some players it is half of the fun to find the correct notes by themselves and solve it without any extra help. Don't use the feature if you are one of those players.
You can also use the keyboard keys (0-9,A-F) for numbers and Shift+(0-9,A-F) for notes.

Ratings and Reviews
I used to search book stores for these large sudokus (killer sudoku) and am so happy to have found this app. You can play at many levels, and the layout is simple to use. I have purchased the app for both my iPad and my Mac Pro and am pleased with both. I had one problem with the display on the mac, contacted the developer and he put a fix in directly. Definitely worth the small amount charged for the app.
Still no skill challenges
No hidden pairs, no rectangles, almost no unhidden triples. Makes it too easy, all you do it click. Great interface, although a number painting mode would make it less tedious. To developer, look for open source hodoku for coding difficultly specific challenges.
Challenging and Well Done
This is the best thought Sudoku interface I have seen so far. Simple and intuitive with no distractions. And 16x16 is much more challenging than a regular Sudoku. Has all the feature I need pluse some I personally don't.
What else can I say - dollar well spent.
With Family Sharing set up, up to six family members can use this app.
