Rolling Doubles in Backgammon: Why Doubles Give You Four Moves
Rolling doubles is the biggest swing of luck on any single turn. Instead of two moves, you get four — and a well-placed double can make a key point, escape a trapped checker, or sprint clear in a race. This guide explains exactly what happens when both dice match, how to play all four moves, the rule that you must use as many as you legally can, and how doubles shape every phase of the game. It also clears up a common beginner confusion: rolling doubles is not the same as the doubling cube. Try it in the interactive lesson above.
What Are Doubles?
Doubles happen whenever both dice land on the same number — double 1s, double 2s, all the way up to double 6s. There is nothing you do to cause them; they are simply the roll. But what you may do with them is special.
Four Moves, Not Two
On a normal roll you play each die once — two moves total. On doubles you play the rolled number four times. Roll double 3s and you have four separate three-point moves to make. You can spread them across four different checkers, pile them all onto one checker, or anything in between, as long as each individual step is legal.
That is a lot of board to cover in one turn. Double 6s moves a total of 24 pips; double 5s moves 20. In a race those big doubles are gold, and even small doubles like double 2s are often enough to make a crucial point with both numbers to spare.
You Must Use As Many As You Can
Just like a normal roll, you must play as many of your four numbers as there is a legal move for. You cannot decline part of a double to keep your position tidy. If only two of the four moves are legal, you play those two and the rest are lost — but you are never allowed to skip a legal move in order to avoid one.
- Doubles = the number played four times.
- Split the four moves across any checkers you like.
- You must make every legal move available among the four.
- Moves with no legal play are simply forfeited.
Playing Doubles Through the Game
In the opening, doubles can instantly make one or two valuable points — double 3s famously makes both the 5-point and the 3-point in a single throw. In the middle game, four moves can complete a prime or escape a back checker. In a pure race, doubles are simply speed: more pips per turn than your opponent can hope to match without rolling their own.
Rolling Doubles Is Not the Doubling Cube
Beginners often mix these up because both involve the word "double." Rolling doubles is about the dice — getting four moves on your turn. The doubling cube is a completely separate device used in match and money play to raise the stakes of the whole game; it has nothing to do with what you roll. This lesson is purely about the dice: when the two numbers match, you move four times.
Frequently asked questions
What happens when you roll doubles in backgammon?
You play the rolled number four times instead of twice. Double 4s, for example, gives you four separate four-point moves to distribute among your checkers.
Do doubles count double the pips?
In effect, yes — you move the number four times rather than two, so doubles move twice as many pips as the same numbers would on a normal roll.
Can you choose not to use all four moves?
No. You must make every legal move among the four. You only forfeit moves that have no legal play available, never to keep a safer position.
Are rolling doubles and the doubling cube the same thing?
No. Rolling doubles is about the dice giving you four moves. The doubling cube is a separate stakes-raising device used in match and money play and is unrelated to what you roll.
What are the best doubles to roll?
It depends on the position, but in a race the big doubles (5s and 6s) cover the most ground, while double 3s is prized in the opening for making two strong points at once.
