After you solve a Puzzle, in the lower right corner appears a thumbs-up and thumbs-down button. I don't quite understand what it means. Does it simply mean that I like or dislike a Puzzle or does it mean I understood the puzzle and don't have to redo it or does it mean that I want to redo it later?
