NOTE: Solving times of advanced Sudoku players.
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.
You can solve it 20% faster using the iPad version.
• 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.
• Clear notes - in manual mode clears all notes
• Hint - press the "Hint" button and one unknown number will be revealed
• OFF - No alerts
• 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.
• 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.
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
Double-tap shortcuts reduce the solving time by 10 - 20%.
When nothing is selected tap 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.
**** NOTE ****
If it looks like you have solved the puzzle, but nothing happens or the numbers don't make sense - please don't write a bad review, but set the alert level to "Wrong Number" to see what is wrong.
Tap the email address on the Help or About screen - we will give you hints and directions of how to resolve any problem.

Ratings and Reviews
Challenging and different
Harder than regular Sudoku and very well done. I was wondering if you guys can add regular sudoku with the same features and options?
The best sudoku app I've ever used
LOVE this app. Tons of puzzles (with 6 levels of difficulty!), all seem to only have one unique solution. Thank goodness because puzzles where the last few squares work several ways drive me CRAZY. Rarely a bug to be seen. I use this app constantly and recommend it to anyone looking for something a bit more challenging than a regular 9x9 sudoku. Now that I have 16x16 the smaller ones just can't hold my interest. Thanks and kudos to the programmer!!!
Wish I could (optionally) turn off "Average Time" indication. At my age, I'm not in any big hurry! :)
Other than that, I like this game VERY MUCH!!!
