Kuku puzzle

Mr. Andrew Reevess of the United Kingdom recently sent my office a copy of his Kuku puzzle. Kuku has 4 settings of difficulty. And Andrew sent it to us at the hardest level. Now I should say that I met Andrew at the New York Toy last year & played with Kuku at the easiest level. The hardest level - I thought - would be ridiculously impossible! However, I did it - to a hearty round of applause from the secretary pool.
