Liar's poker is an American bar game that combines statistical reasoning with bluffing, and is played with the eight digits of the serial numbers on a U.S. dollar bill. The numbers are usually ranked with a zero counting as a ten, and a 1 being highest as 'ace'. Normally the game is played with a stack of random bills obtained from the cash register. The objective is to guess how often particular digits appear across all bills held by players, with guesses increasing in value or quantity until a player challenges the most recent guess.

'Liar`s poker,' played with the serial numbers of the dollar bills in one`s pocket, is still widespread. And many a family tavern runs a local football pool for the amusement of customers.

  4. The name Liar s Poker also applies to a game played with dollar bills, which involves their serial numbers and is related to Liar s Dice.

Liar's dice is a similar game played with dice, and Commune is a similar game played with cards.

Gameplay

Each player takes a dollar bill and looks at its serial number, without letting any other players see. A player is chosen to start, and they make an opening bid on how many of a particular digit they believe appears across all serial numbers held by the group. For example, if the first player bids three 6s, he is predicting that there are at least three 6s among all the players' banknotes, including his own.

The next player can bid a higher number at that level (three 7s), any number at a higher level (four 5s) or challenge. The game continues clockwise around the table until a particular bid attracts a challenge from every player other than the bidder.

When a challenge is made, each player reveals how many of the bid number they have on their note's serial number. If the challenge was correct (and the number on the bills is lower than the challenged bid), the bidder loses a dollar to each of the other players. If the challenge was incorrect, the bidder wins a dollar from each of the other players.

Trading floor personnel of the kind to be found in Michael Lewis's book in the 1980s often played a variant on the above whereby a player who is called by all the other players can raise his own bid, thereby doubling the bet. For example, if he is called by all the other players on five fours he can then bid, say, five fives, with the bet doubled to two dollars. Called again, he might then go to five sixes, with the bet increased to four dollars. In this way, a clever player might reach his intended target of, say, five aces and win, say, sixteen or thirty-two dollars from each of the remaining players instead of merely one dollar. For this reason, many finance professionals discounted Michael Lewis's story of the 'million-dollars-no-tears' bet allegedly proposed by CEO John Gutfreund on the grounds that there can be no single-stake bet in Liar's Poker because one cannot know whether or not the bet will be escalated in this way.

COMMENTS
Having finished Liar's Poker: Rising Through the Wreckage on Wall Street by Michael Lewis, last week, it seemed appropriate to explain the rules of the game. Yes, a review might have been interesting, but definitely not more entertaining (and I would consider the book an entertaining read). So, in the spirit of trading sites everywhere, I have written this tutorial to explain the basics of liar's poker:
1) There are several version of liar's poker. One involving bidding and another more in the spirit of poker. Because the bidding version appears to be the most popular, and because Micahel Lewis features it in his book, I will discuss the general rules for that game. As with any game, remember to clarify rules before beginning since more than a single version of the game likely exists.
2) The game requires 2 or more players and each player needs a dollar bill (several if you want to increase the uncertainty of serial numbers drawn).
3) Put all bills face down, covering the serial number, into a pile in the center of the group. Shuffle the bills.
4) Have each player take a bill. Do not show it to any other players. Keep your 'hand' covered, just like in a game of cards.
5) Look at your serial number. In general, 1's count as aces and 0's count as tens, but make sure to clarify this at the beginning of the game. Some versions play with 0 being the lowest number and 9 being the highest. Either way works out well. Count the number of times each number appears in your serial number. This is your hand. Remember it.
6) Begin the bidding. You can choose the starting player in any number of ways. If you have only two players, a coin toss works well. Otherwise, rolling dice or picking a card. Use your imagination.
7) Make a bid. That means, make a bet on how many of a certain number you believe to be among all the serial numbers. Say you have 2 5's on your serial number. You could safely bid 2 fives, as you know there to be two five's for a fact.
8) Continue to the next person. This person can now bid a higher amount of the number you last bid on, say 3 5's; or, they can bid a higher amount on a lower number, say 4 4's or 4 2's; or, they can bid on any amount of a higher number, say 2 6's or 1 ace.
9) Another option everyone after the first player has is to call the last player's bid a lie, or a bluff. Say you do not think there could possibly be 4 aces among all the serial numbers, but that was the last bid. You could call the last player's bid a bluff.
10) Now, the next person can agree with you and also call that player's bid a bluff. But if they do not believe it to be a bluff, they can also continue the bidding in the manner explained in step 8.
11) If the belief that a person has in fact bluffed becomes the consensus of the entire group, everyone must show their serial numbers.
12) Count up the serial numbers.

Poker13) If the person being called the liar actually bid correctly (e.g. the player said there were 5 aces and there were, or there were more), then that player wins. Each player gives him a dollar, or a point, whichever has been decided upon.
14) If the person is incorrect, then that player must give everyone else a dollar, or a point, whichever is decided upon. You do not have to play for dollars; playing with smaller or larger amounts works just as well.
