There's only one simple rule: never get three wrong in a row - or you're done. No saves, no helps, no multiple choice, "500 Questions" keeps you on the edge of your seat to see if any of these geniuses can do it. It is the ultimate test, where intellect, strategy and stamina are all equally essential in order to win.
