Deal or No Deal for Nintendo DS is a video game adaptation of the popular television game show. Players select one of 26 briefcases, each containing a cash amount between 0.01 and 1,000,000 dollars. As players open briefcases, a banker offers deals based on the remaining amounts. Players must decide whether to accept a deal or continue revealing cases, aiming to secure a higher prize.
Deal or No Deal is based on the TV game show of the same name. It puts one contest against a banker. At the start of the game, the player choose one of the 26 briefcases. They contain prize money ranging from $.01 to $1,000,000. The different amounts are shown on a game board. Each round the player has to open a number of the remaining briefcases which are then marked on the board (six in the first round, five in the second, four in the third). Based on the remaining amount of money, the banker offers the player a deal, a certain amount of money, based on odds. The player can choose to accept the deal when large sums are gone, or decide to go through. After the third round the briefcase is opened and if it contains a higher sum than what the banker offered, the player has made a great deal.
