Players hold random dollar bills with close attention to their own bill serial number. The objective of the game is to bluff the opponents into believing that your bid does not exceed the combined sum of all of the serial numbers...The game requires great mathematical skill because the probability calculations are extremely complex. But even more essentials is a 'poker face', the ability to lie convincingly.
if one player bids three 4s, he predicts that within all of the dollar serial numbers held by all players, there are at least three 4s. If the player's bluff is not called, the next player must either bid a higher frequency of any other digit (five 2s) or can bid a higher number at the same frequency level (three 6s).listen to a reflection on the psychology ‘Liar's Poker’
