After the cube has been offered and accepted, a further cube action is called a re-double.

After accepting the cube and doubling the stakes of the game, a player can then re-double the opponent, again doubling the stakes. If you accept a double when your opponent is two away from winning, you have nothing to lose with a Re-double.

Bids which have different meanings according to the context and bidding system, but are nominally intended to increase the stakes.
