Backgammon
Rules
Backgammon is a game for two players. The board consists of four quadrants divided into six fields. Each player receives 15 checkers. The object of the game is to bring one’s own checkers (either red or white) into one’s “home“-quadrant and to bear them off from there. The first player to do this wins.
The game is played using two dice. A player can decide whether to move just one checker using both dice or two checkers using one die each. Checkers can only be moved onto fields which are either completely empty, occupied by one’s own checkers or by only one opposing checker. Checkers have to be moved in accordance with the direction of play (marked with the red or white arrow), as checkers cannot be moved in the opposite direction.
A player can knock out their opponent by either landing (or stopping) on a field occupied by only one of the opponent’s checkers. This checker is placed on the middle of the board and has to be brought back into play from the beginning. This is accomplished during the next turn. If the checker cannot be brought back into play, the player’s turn is over and it is again the opponent’s turn.
The checkers can only be borne off once all checkers have been brought back into the home quadrant. The dice are rolled to bear off checkers into the rack.
If a player rolls doubles, s/he gets four moves. This is called Doublets. A player wins a Backgammon if the opponent has not yet borne off any checkers and has at least one checker on the starting quadrant or on the center bar. A player wins a Gammon if s/he bears off all checkers before the opponent can bear off a single one.
The game is over once a player clicks “Finish“ or one of the players gives up and the opponent accepts this.
Points
A player who has borne off all checkers at the end of a game receives one point. If the opponent still has all checkers on the board at this time, the winner gets two points, and three points if the opponent still has a checker in the starting quadrant.
If a player gives up and this is accepted by the opponent, this move is counted as a Gammon provided that the player who gives up is 60 points behind and has not borne off any checkers into the rack.
If a player wins a Backgammon the score is tripled, and doubled for a Gammon. In Beavers a player can re-double and retain the doubling cube. An example: Player X doubles the stakes to 2 points, Player Y accepts and re-doubles to 4 points. If Player X passes, s/he would lose 2 points. If s/he accepts, the doubling cube is set to 4 points and stays with Player Y. A multiplier showing points won is displayed in the rack, e.g. 32 means 32 * points won.
