Deal or No Deal is a type of live casino game designed and named after the famous TV lottery show. There are up to 26 briefcases, each briefcase holding a random sum of a cash prize. The game is played against a host who's opening the boxes one by one, revealing the amounts of money contained in each one of them. After the sum is revealed by the presenter, he asks a simple question: "Deal or no deal?". If the player rejects an offered sum of money, the boxes are opened until he or she makes a choice. There is a chance that each new briefcase will contain a bigger sum of money than the one before, but the amount is likely to decrease as well.
Besides, there is one briefcase that is randomly chosen and kept by hosts at the beginning of the game round. The value of the box is not revealed but there is a chance that the sum of money in it is drastically bigger than in any other of the boxes. The objective of the game is to rather stick to the initial box or pick the one that's more valuable than it.
The content of the live casino version of Deal or No Deal is pretty similar to the TV show. Instead of briefcases with money prizes, there are reels and rows representing them. Each box has a number on it, and you can stick to your bet amount, opening new boxes and revealing the prizes kept in them until you are satisfied with your catch. Don't get disappointed in case of a loss on your pick; there's always a chance that the next box you open will present an even more significant cash prize.
