On Povich, I believe it initiated a sudden-death lockout question.
On Barry, if I remember my Quiz Show correctly, you started a new game with the $X-per-point stakes increased. (I want to say they doubled.)
I guess what I'm looking for is did anybody see it happen. I know both of the above circumstances happened when the game ended in a 21-21 tie from correct answers. But, on either version (and I know it's less likely on the original, since that was staged for most of its run), did any players choose to stop after round 2 while the scores were tied?
Wiki seems to imply that the game value increased on the Jack Barry version only when the game ended 21-21. The article also suggests that the game would end after five rounds (or categories) of questioning, which presents another opportunity for a non 21-21 tie.
