Deal or No Deal is the name of several closely related
The gameplay of the show differs from country to country. In some countries, there is a preliminary contest in which the studio audience is whittled down to one final contender by several trivia question rounds, this final contender then proceeds to the main game. There are also some versions with the number of players equal to the number of cases, each player receives one case. Via a short trivia round or a random selection, one player is selected to be the contestant for the main game with his case. In other countries, there is only one preselected contestant who will play the main game without any preliminary contest.
The main game revolves around the opening of a set of numbered briefcases, each of which contains a different prize (cash or otherwise). The contents (i.e., the values) of all of the cases are known at the start of the game, but the specific location of any prize is unknown. The contestant claims (or is assigned) a case to begin the game. The case's value is not revealed until the conclusion of the game.
The contestant then begins choosing cases that are to be removed from play. The amount inside each chosen case is immediately revealed; by
This process of removing cases and receiving offers continues, until either the player accepts an offer to 'deal', or all offers have been rejected and the values of all unchosen cases are revealed. Should a player end the game by taking a deal, a pseudo-game is continued from that point to see how much the player could have won by remaining in the game. Depending on subsequent choices and offers, it is determined whether or not the contestant made a "good deal", i.e. won more than if the game were allowed to continue.
Since the range of possible values is known at the start of each game, how much the banker offers at any given point changes based on what values have been eliminated (i.e. the offer increases if lower values are eliminated and decreases if upper values are eliminated). To promote
Only a few people have ever won the top prize on any version of the show (see table below). For a contestant to win the top prize the player would have to select the case containing the top prize and reject every offer the banker makes during the game. The chances of a player selecting the top prize are 4–5% depending on how many amounts are in the game.
