A battle of reality-show wills kicks off tonight when NBC's special singing event, Clash of the Choirs, faces off against ABC's week-long game show, Duel. The tournament-style Duel pits 24 contestants against each other in a battle of trivia and strategy, with the winners from each of the game's first five nights moving on to face each other in Sunday's finals.

Based on a French game show, Duel pits contestants head to head in a match that mixes Who Wants to Be a Millionaire with Vegas-style gambling. Contestants place bets on how sure they are that their answers to various trivia questions are correct, and right answers drive up the jackpot — while just one wrong answer gets a player sent home.

Questions cover a wide variety of pop culture trivia, from the number of eyelids on a camel's eye (three) to which footwear company uses Heidi Klum's designs (Birkenstock). Of course Duel requires knowledge, but there's also luck involved; I had several great rounds on the show's online game, then hit a string where I didn't know even the first question. Duel also adds in strategy, with the betting and the twist that each winner gets to choose his or her opponent in the next round.

In general, I've found TV trivia shows too drawn-out for their own good ever since Millionaire. But the fact that this one is only six nights long makes me want to see what it's all about. Will you be watching Duel? To watch a preview, just read more.
