Can I change the appearance of the board?
Yes, in settings under the heading ‘Appearance’

I’m stuck on a puzzle..
Try using the hinting functionality, it shows you possible changes.

It says there are notes in error..
This means some of the numbers in the notes can’t be placed in their cells, because it would violate the Sudoku constraints(ex: a cell can’t have the note 4 if the cell next to it has the value 4). Try using the clear notes and fill notes actions to solve this.

Yes, select ‘notes’ in the setting ‘Always highlight conflicting values’

Can I change how hints works?
Yes, you can select what strategies the hint button should use, or if it should simply set a correct value.

What does the Analysis tool do?
The analysis tool checks what strategies can be applied to the puzzle in its current state, what strategies are needed to solve the puzzle, it’s difficulty and if it has a unique solution or not.

Can I capture sudoku puzzles with my camera and solve them in the app?
This is a planned feature.
