In Spider Solitaire, how do you win games on the hardest level? - pretty good solitaire name and serial

Sometimes when I'm bored at work, playing Spider Solitaire. I'm pretty good in the use of two combinations, but it is not possible to win four combinations! Anyone out there good at what level? What is the secret? Began to feel he is one of the rigged carnival games that you can not win, lol.
