Duel (US)

In a cutting edge format - combining trivia challenges like those on "Who Wants to Be a Millionaire" with the strategy played in the "World Series of Poker" -- contestants will once again find themselves in intense head-to-head matches, reacting quickly under pressure and outsmarting their opponents by using strategy and deception, as well as intellect and skill, in the race to win big money.

Contestants on "Duel" will be chosen for their confidence and charisma, a love of trivia and an obsession for competition. Like the previous incarnation of the show, when contestants wins a duel, they will pick their next opponent from three potential competitors, having only been given a limited amount of information about them -- the twist being that not all may be as it appears with these challengers.
