FEATURES EXPLAINED:• 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• Hint - press the "Hint" button and one unknown number will be revealed? 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 it2. When there is only one note in a certain square - double tap it and the note will become the number3. 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%.? NOTEIf 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.?
