It would seem that the Challenge is more challenging this year – we have not received a single correct answer yet. This is the first time the Challenge has withstood more than 24 hours!
Please remember that you do not have to be the first one to solve it – the Advisory Board will select another winner among the next ten correct answers. The criteria for the other selection is the elegance of the answer. In short, you can win with both speed and style 🙂
