Backgammon Dictionary

An offer made by one player to his opponent during the course of the game (on that player's turn, but before he has rolled the dice) to continue the game at twice the current stakes. The opponent may refuse the double, in which case he resigns the game and loses the current (undoubled) stakes. Otherwise, he must accept the double and the game continues at double the previous stakes. A player who accepts a double becomes owner of the cube and only he may make the next double in the same game.

Doubles.

Doubling cube.

A cubical block, slightly larger than a regular die, with the numbers 2, 4, 8, 16, 32, and 64 marked on its faces. It is used for keeping track of the increase in stakes of the game and the player who next has the right to double. The cube starts in the middle with the number 64 facing up (representing a value of 1). When you offer a double, you turn the cube to its next higher value and pass it to your opponent. If he accepts your double, he places the cube on his side of the board and becomes the owner of the cube. After the first double of a game, only the player who last accepted a double may make the next double. Rules that affect use of the doubling cube:  automatic doubles, the Jacoby rule, and beavers.

Offering a double in anticipation of a good roll.
