If you've seen the KotH pilot, hosted by Robert Earle, and ever wondered what the 10th step's category sign read, wonder no longer. Take a look at this image from a website of CBS engineering alumni...

...this photo was probably taken after shooting for the KotH pilot wrapped up. Notice the champion/"king" descending the staircase.

The final step's category is "The Numbers Game". As to what the category entailed, to quote Mike Burger in his review of the pilot on MikeBurger.com/pilots, "The world will never know."

If you take a little time to wander about the rest of the CBS retirees website, you'll see some other behind the scene pictures of the East Coast facilities, as well as a list of all the CBS announcers, and a nice listing of all the NYC studios used by the Big 3 networks. Nice find!!!
