Cash or Crash is a card-based bluff game in the same vein as the classic Liar's Dice, but offering players a greater degree of control and more strategic and tactical options.
Players start with identical hands of ten cards, each showing different numbers and different combinations of the three commodities in the game: gold, wheat and oil. Normally, each player "invests" two of these cards to start the round, placing them face down in front of him. Players use their own hidden information (the cards they have invested) and the offers of other players to guess the real market value (i.e. the total quantity of each commodity on all players' cards), while trying not to give too much themselves.
