backgamon Doubling cube

When can I double my opponent?

Generally, you can double (both in real money and in fun money games) under the following conditions:

1. The doubling cube is available (as set in the negotiation pop up window before approving the game).
2. The game limit is set higher than the original stake (set in the negotiation window).
3. The auto roll function is disabled (unmarked checkbox in the game board screen).
4. The cube is in the middle (yet unused by any player and is available for either player at that point to initiate the first double).
5. The cube is on your side.
6. When Crawford rule is not applied.
