Couchtuner Deal or No Deal Watch Series Online Free. Airing from 2005 to 2009 on NBC, the game show series returns to primetime TV with original host Howie Mandel. A contestant must choose from 26 sealed briefcases containing a marker for various amounts of cash — from one penny to $1 million. The player then eliminates the remaining 25 cases one by one. The chosen ones are opened and the amount of money inside revealed. After several cases are opened, the player is tempted by the Banker to accept an offer of cash in exchange for not continuing the game and possibly winning a larger sum of money.
