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.

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 appearDouble-tap shortcuts reduce the solving time by 10 - 20%.NUMBER-FINDER FEATURE:When nothing is selected tap a number in the notes pad or in the number pad.

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.CONTACT USTap the email address on the Help or About screen - we will give you hints and directions of how to resolve any problem.Enjoy :-)
