Pretty good

Challenging, excellent autofill. Agree that the hint option is weak and frustrating; it simply provides the answer to one square without any explanation of the logic that lay behind it, or what you should be looking for. Many sudoku programs have this logic included in their hint functions & this would change my rating to a 5 star
