About Gammons and BackgammonsAt the ending part of the game , if the losing player has been able to borne off at least one checker, he loses only the value that is showing on the doubling cube (the value will only be one point if there have been no doubles on the game). But if the loser was not able to borne off any one of his checker then he is gammoned and he then loses double the value of the doubling cube. A worse penalty happens if the loser was not able to borne off any of his checkers and he also still has a checker on the bar or in the winner’s home board. In this situation he is backgammoned and loses three times the value of the doubling cube.
Optional rules in backgammon
The optional rules indicated below is actually used quite extensively by many backgammon players:
Automatic doubles – If the player rolls identical numbers on the first roll, the stakes are automatically doubled. The doubling cube is turned to 2 and this is placed in the middle. Before playing, players would usually agree to limit the number of automatic doubles to just one per game.
Beavers – When a particular player is doubled, he can immediately decide to redouble while also keeping possession of the cube. This is called a beaver. The original doubler can then have the option of either accepting or refusing the redoubling just like in a normal double.
Jacoby Rule – Gammons and backgammons will count only as a single game if neither one of the players have offered a double for the duration of the whole game. This particular rule helps in speeding up the game play by getting rid of situations where a player avoids doubling so it allows him to play on for a gammon.
