For example, a player leading a 9-point match by a score of 7—5 would be very reluctant to turn the doubling cube, as their opponent could take and make a costless redouble to 4, placing the entire outcome of the match on the current game.
Conversely, the trailing player would double very aggressively, particularly if they have chances to win a gammon in the current game.
In money play, the theoretically correct checker play and cube action would never vary based on the score. In , Emmet Keeler and Joel Spencer considered the question of when to double or accept a double using an idealized version of backgammon.
In their idealized version, the probability of winning varies randomly over time by Brownian motion , and there are no gammons or backgammons.
To reduce the possibility of cheating, most good quality backgammon sets use precision dice and a dice cup. Online cheating has therefore become extremely difficult.
In State of Oregon v. Barr , a court case pivotal to the continued widespread organised playing of backgammon in the US, the State argued that backgammon is a game of chance and that it was therefore subject to Oregon's stringent gambling laws.
Paul Magriel was a key witness for the defence, contradicting Roger Nelson, the expert prosecution witness, by saying, "Game theory, however, really applies to games with imperfect knowledge, where something is concealed, such as poker.
Backgammon is not such a game. Everything is in front of you. The person who uses that information in the most effective manner will win.
Walker concluded that backgammon is a game of skill, not a game of chance, and found the defendant, backgammon tournament director Ted Barr, not guilty of promoting gambling.
Early Muslim scholars forbade backgammon. Enthusiasts have formed clubs for social play of backgammon. A backgammon chouette permits three or more players to participate in a single game, often for money.
One player competes against a team of all the other participants, and positions rotate after each game. Chouette play often permits the use of multiple doubling cubes.
Backgammon clubs may also organize tournaments. Large club tournaments sometimes draw competitors from other regions, with final matches viewed by hundreds of spectators.
Winners at major tournaments may receive prizes of tens of thousands of dollars. Starting in January , tournament directors began awarding GammonPoints,  a free points registry for tournament directors and players, with GammonPoint awards based on the number of players and strength of field.
The first world championship competition in backgammon was held in Las Vegas , Nevada in Tim Holland was declared the winner that year and at the tournament the following year.
For unknown reasons, there was no championship in , but in , Tim Holland again won the title. In , Lewis Deyong, who had promoted the Bahamas World Championship for the prior three years, suggested that the two events be combined.
By the 21st century, the largest international tournaments had established the basis of a tour for top professional players.
Major tournaments are held yearly worldwide. PartyGaming sponsored the first World Series of Backgammon in from Cannes and later the "Backgammon Million" tournament held in the Bahamas in January with a prize pool of one million dollars, the largest for any tournament to date.
The event was recorded for television in Europe and aired on Eurosport. In , the WBA collaborated with the online backgammon provider Play65 for the season of the European Backgammon Tour and with "Betfair" in When backgammon is played for money , the most common arrangement is to assign a monetary value to each point, and to play to a certain score, or until either player chooses to stop.
The stakes are raised by gammons, backgammons, and use of the doubling cube. Backgammon is sometimes available in casinos.
Before the commercialization of artificial neural network programs, proposition bets on specific positions were very common among backgammon players and gamblers.
The game is included in Clubhouse Games: 51 Worldwide Classics for the Nintendo Switch , a collection of tabletop games. Backgammon software has been developed not only to play and analyze games, but also to facilitate play between humans over the internet.
Dice rolls are provided by random or pseudorandom number generators. Real-time online play began with the First Internet Backgammon Server in July ,   but there are now a range of options,  many of which are commercial.
Backgammon has been studied considerably by computer scientists. Neural networks and other approaches have offered significant advances to software for gameplay and analysis.
The first strong computer opponent was BKG 9. Early versions of BKG played badly even against poor players, but Berliner noticed that its critical mistakes were always at transitional phases in the game.
He applied principles of fuzzy logic to improve its play between phases, and by July , BKG 9. It won the match 7—1, becoming the first computer program to defeat a world champion in any board game.
Berliner stated that the victory was largely a matter of luck, as the computer received more favorable dice rolls. In the late s, backgammon programmers found more success with an approach based on artificial neural networks.
Its neural network was trained using temporal difference learning applied to data generated from self-play.
Tesauro proposed using rollout analysis to compare the performance of computer algorithms against human players.
The rollout score of the human or the computer is the difference of the average game results by following the selected move versus following the best move, then averaged for the entire set of taken moves.
The strength of these programs lies in their neural networks' weights tables, which are the result of months of training. Without them, these programs play no better than a human novice.
For the bearoff phase, backgammon software usually relies on a database containing precomputed equities for all possible bearoff positions.
Computer-versus-computer competitions are also held at Computer Olympiad events. The artifacts included two dice and 60 checkers, and the set is believed to be to years older than the Royal Game of Ur.
On the board found at Shahr-e Sukhteh, the fields are represented by the coils of a snake. Touraj Daryaee —on the subject of the first written mention of early precursors of backgammon—writes:.
The use of dice for the game is another indication of its Indic origin since dice and gambling were a favorite pastime in ancient India.
According to the historical legend, the Indian king Dewisarm sends his minister Taxritos to Persia with the game of chess , and a letter challenging Sasanian King Khosrow I to solve the riddle or rationale for the game.
Khosrow asks for three days to decipher the game, but initially, no-one in the court is able to make any progress.
On the third day, Khosrow's minister, Wuzurgmihr, successfully rises and explains the logic of the game. As a reciprocal challenge, Wuzurgmihr constructs the game of backgammon and delivers it to the Indian king who is unable to decipher the game.
In the 11th century Shahnameh , the Persian poet Ferdowsi credits Burzoe with the invention of the tables game nard in the 6th century.
He describes an encounter between Burzoe and a Raja visiting from India. The Raja introduces the game of chess , and Burzoe demonstrates nard , played with dice made from ivory and teak.
Murray details many versions of backgammon; modern Nard is noted there as being the same as backgammon and maybe dating back to — AD in the Babylonian Talmud,  although others believe the Talmud references the Greek race game Kubeia.
The history of backgammon can be traced back nearly 5, years to its origins in Mesopotamia modern-day Iraq. Concede Speak Multiplayer.

Cool animated gifts, abuse-free phrases and emoticon system! Quick Introduction to Backgammon — basic rules Backgammon is the most popular board game for 2 players.
The board consists of 24 triangles with alternating colours — these are called points. The points are separated into four equal groups, known as Home and Outer boards.
Every player has 15 checkers in predefined locations on the board and tries to move all of them safely to his home board. The main objective of the game is to move all checkers you own to your own home board and then bear them off.
The first player do achieve that is declared a winner. Points, that have only one checker on them are called Blots. The player that has checkers on the board must return them to play before playing his other checkers.
It is possible to have no possible moves — in this case the turn is ended and the opponent rolls the dice.
By default, every game yields 1 point per win. If your opponent accepts, the yield is doubled, if he declines, the current doubling cube value is assigned to you.

The object of backgammon is to move all your checkers around the board in a clockwise motion and ultimately bear off the checkers from the board.
The first player to remove all their checkers is the winner. Alternate turns with your opponent moving checkers toward your home in the upper right hand quadrant of the backgammon board.
Move checkers by rolling the dice. The numbers on the dice refer to how many spaces you may move with one or more checkers.
Highlights show you where the checkers can possibly move. If you roll doubles, you get to move each die twice, concluding in four moves for that turn.
You may move your checkers onto any Point so long as it is occupied by your checkers, is empty, or has 1 opponent checker. You may not move your checkers onto a Point with two or more opponent checkers.
If you land on a Point with one opponent checker, you knock the opponent's checker off the board and send it back to the beginning.
The opponent must now roll and move into an empty spot in your home territory to get that checker back into gameplay.
This internet game requires strategic thinking skills, so get ready to use your brain like never before. Will you manage to get ahead of your opponent and remove all your checkers first?
