Move the Potter Paddle and stop Voldemort from taking over the world! the original Voldemort is the green one. If a clone of Voldemort touches the line, it takes away 100 points. But do not worry, you get 120 points each time you hit Voldemort. If the real Voldemort touches the line, you fail.
I would like to thank J.k Rowling obviously. Guys: visit Pottermore.com if you love Harry Potter!
