Using the Doubling Cube
The doubling cube is used to increase the stakes of the game. The cube contains the numbers: 2, 4, 8, 16, 32, and 64. In the beginning of the game, the cube is turned to 64 and is placed face up in the middle of the bar. This represents that the game is being played for 1 point. When a player feels that they have gained an advantage, he/she may increase the stakes of the game by increasing the cube to 2. The opponent may either accept or resign from the game and lose the point. The cube can only be turned before the player rolls the dice on their turn. The player who agrees to increase the cube becomes the owner of the cube. Only the owner may decide whether to increase the doubling cube.
