Duel
Duel is a American gameshow hosted by Mike Greenberg that aired from December 17 to December 23, 2007. The show aired as being a championship at 8:00 PM from Monday through Friday with all the finale on Sunday.
The series's site explained the application as a cross between Who wants to Be a Millionaire? And the World Series of Poker. The game was played at a head to head format by which contestants answered general trivia questions, with erroneous answers leading to a jackpot. The winner of this Duel jackpot of $1,720,000 was Ashlee Register, whose grand total was almost $1.8 million combined with all previous winnings, which makes her the first highest female game show money winner at the U.S. at the moment.
The next season aired at 9:00 PM from April 4 to July 25, 2008 at a weekly format together with rules.
