Lots of ads, but that is to be expected from shovelware. As far as crossword puzzles go, this is by far the worst way to implement it. The programmers couldn't be bothered to actually try to make a good crossword game and instead just fill a square with words where none of them overlap, not a single word uses a letter from any other word. Makes for an extremely boring experience. I guess if you're just learning to read this might be a good app to help you learn the alphabet.
