Players begin with nine money cards totaling 13,000 in various denominations, including two cards worth zero. In turn, players roll a colored die and then offer at least one face-down money card to the player indicated by the roll. That player may either accept the offer or challenge it. If challenging the offer, the player rolls a numbered die. If the number is greater than the amount of money offered, the offering player must add at least one face-down card to the mix and begin the process anew. If the die roll is equal to the money, the offer must be accepted. If the roll is less than the offer, the offering player keeps his money and the challenging player must pay the offering player the amount offered. First player reaching 25,000 wins. A quick, light game of bluffing. - BoardGameGeek
