Pirate's Bluff

From BoardGameGeek:

Pirate's Bluff is a bluffing card game for long sea voyages. It is similar to the traditional game Liar's Dice, in that players start with a random secret hand, and try to guess through bidding what every other player holds. Bidding happens in real time, with no turns, requiring lightning-fast decisions and nerves of pirate steel. The game uses a 72-card deck plus coins or poker chips for keeping score. The Pirate's Bluff deck contains eight copies each of the numbers 1 through 8, plus eight wild cards (rank 0), for a total of 72. Once the action starts, players can call out a bid at any time, escalating the difficulty until someone calls their bluff. When a bid is called, all players show their hands. If the bidder is right, the bidder wins and the caller loses. If the bidder is wrong, then the caller wins and the bidder loses. -description from the publisher
