I like Dark Sudoku because it is the only app that supports highlighting of candidates, to solve puzzles with Chaining Strategies. But I miss an option to scan sudoku puzzles from papers or websites to import them. There is also no option to import a sudoku puzzle scanned with another app.

The app did not autosave my game! Hit "resume" to see the game completely reset. Uninstalled it instantly, how annoying. Also, if you're used to other Sudoku apps beware: this app will not mark your mistakes as you go. Not a bug (I think), just makes the game a little harder.

Very good design . But highlights for candidates lack the pencil marks highlightsl. It is difficult to see the poiinting and claiming options which is essential for solving sudoku .
