| Total points to go | Points on which your man or men are located | In two rolls you have the following: |
|---|---|---|
| 12 | 6-6 | 78% |
| 11 | 6-5 | 88% |

What happens at the end of backgammon?
At the end of the game, the losing player must pay the winning player the stake times the number of pieces still remaining on the board.
How are backgammon odds calculated?
For example, the probability of rolling at least one 6 out of two dice is 11/36. Rolling a 6 as a sum of two dice is 5/36. The probability of rolling at least one 6 or rolling a six as a sum of two dice is 11/36 + 5/36 = 16/36.
What are the odds of rolling a double six in backgammon?
The probability of rolling any double is 16.6%, and the probability of rolling a non-double is 73.4%. So if your opponent rolls 6-6, 2-2, 3-3, 5-5 then they actually have had an improbable run of luck….
| Open Points | 1 piece | 2 pieces |

Why do you need to know the probabilities in backgammon?
To formulate strategies in backgammon it is helpful to know some basic probabilities. Since a player can use one or two dice to move a particular checker, any calculation of probabilities will keep this in mind.
Can you use two dice to move a checker in backgammon?
Since a player can use one or two dice to move a particular checker, any calculation of probabilities will keep this in mind. For our backgammon probabilities, we will answer the question, “When we roll two dice, what is the probability of rolling the number n as either a sum of two dice, or on at least one of the two dice?”
How are numbers divided during a turn in backgammon?
During a turn in backgammon a player may move his or her checkers or draughts according to the numbers shown on the dice. The numbers rolled can be split between two checkers, or they can be totaled and used for a single checker. For example, when a 4 and a 5 are rolled,…
What does a direct move in backgammon mean?
A direct move is a single move in the range 1 to 6, e.g. 13/8. An indirect move consists of two or more consecutive moves with a single piece, e.g. 13/10 10/8 from a roll of 3-2. All the moves must be legal (i.e. land on an available point). So what does it all mean? Your chances of getting back from the bar are better than they look.
