When Nate and Sarah Harrison arrived at "Deal or No Deal," they were surprised to learn that not only were they chosen to play in the Million Dollar Mission game, but half the board is filled with $1 million cases! The Banker, ready to test their new nuptials when they face-off for the million dollars, is confident he can still beat the odds.

"Are you kidding me?" said the Banker. " Face it America. You can't beat me. A lemur would have a better chance of winning the million."

Determined to give away the top prize, the Million Dollar Mission first started on September 26, 2007. For every contestant who did not win the top prize of $1 million, an additional $1 million briefcase was added to the board. Last fall, over the course of three weeks, the Million Dollar Mission went up to a total of eight $1 million cases, but no one took home the big money. Determined to find that first-ever million-dollar winner, the Million Dollar Mission returned on January 2, 2008, starting with two $1 million cases on the board. Over the past several weeks, with no one winning the top prize, it's now up to thirteen $1 million cases on the board.

"Deal or No Deal" premiered on December 15, 2005. In the history of the show, out of 199 contestants in 149 episodes, only 12 have held the million dollars in their case, but have been unable to go the distance for the top prize. The highest amount that was taken home in a game where the top prize was $1 million was $471,000.
