Duel is an American gameshow hosted by Mike Greenberg that aired from December 17 to December 23, 2007. The show aired with all the finale on Sunday as being a week-long six-episode tournament at 8:00 PM from Monday through Friday. The program was described by the blog of the show like a cross between Who wants to Be a Millionaire? And the World collection of Poker. The match was played in a format by which contestants replied trivia questions that were general, together with answers. The winner of this Duel jackpot of $1,720,000 was Ashlee Register, whose expansive total was nearly $1.8 million when combined with all previous winnings, which makes her the first highest female match show money winner in the U.S. during the moment. The next season aired in a weekly format with rules from April 4 at 9:00 PM to July 25, 2008.
