What is Doubling in Backgammon?

Backgammon is a classic board game that has been enjoyed for centuries. It is a game of strategy and luck, where players aim to move all their pieces off the board before their opponent does. One interesting aspect of backgammon is the concept of doubling.

The Basics of Doubling

Doubling in backgammon refers to a strategic move where one player offers to double the stakes of the game. This means that if accepted, the winning player will win twice as many points or money as they would have without doubling.

In order to double, a player must first be in possession of “the cube,” which serves as a marker indicating the current level of stakes. The cube starts at 1 and can be increased up to 64 (referred to as owning “the center” or “the cap”), depending on house rules or tournament regulations.

Purposes and Strategies Behind Doubling

The primary purpose behind doubling in backgammon is to increase excitement and add intensity to the game. It introduces an additional element of risk-taking and decision making for both players involved.

Strategically, offering a double can be advantageous under certain circumstances:

  • Gaining an advantage: If you believe you have an advantage over your opponent due to favorable positions or dice rolls, doubling allows you to capitalize on this edge by potentially increasing your winnings.
  • Create uncertainty: Offering a double can introduce doubt into your opponent’s mind. They may hesitate accepting it if they are unsure about their position, giving you more leverage during negotiations.
  • Mind games: Doubling can also serve psychological purposes by putting pressure on your opponent. The decision to accept or decline a double can be influenced by factors such as risk tolerance, confidence, and the desire to maintain an image of strength.

The Process of Doubling and Acceptance

Once a player offers a double, their opponent has two options:

  1. Accepting the Double: If the offer is accepted, the game continues with new stakes. For example, if the cube was at 2 when doubled and accepted, it becomes 4 for both players.
  2. Declining the Double: If declined, this results in an immediate victory for the player offering the double. They win an agreed-upon number of points based on whether it was a money game or match play.

Note that once a double has been declined during a game, only that particular player can initiate any subsequent doubles until they lose possession of “the cube” through either accepting or declining another offer.

Gammons and Backgammons

In backgammon scoring terminology, there are additional incentives related to doubling known as gammons and backgammons. These occur when one player wins before their opponent manages to bear off any pieces from their inner table (home board).

  • Gammon: A gammon occurs when you win while your opponent still has one or more checkers left on your home board. In this case, you receive twice as many points/money as stipulated by doubling rules.
  • Backgammon:A backgammon is even more valuable than a gammon because it happens when you win while your opponent still has not moved any pieces past your five-point (bar) line. This achievement earns three times as many points/money compared to the original stakes.


Doubling in backgammon adds an extra layer of excitement and strategy to the game. It allows players to increase their potential winnings by taking calculated risks and challenging their opponents’ confidence. Understanding the basics of doubling, its purposes, and associated scoring scenarios like gammons and backgammons can help elevate your backgammon gameplay to new heights.
