Backgammon Online

If a game ends normally, the outcome of the game is equal to 1 point. In the case of a gammon, the outcome is 2 points, and in the case of a backgammon, 3 points. If the doubling cube is used, the value of the cube at the end of the game is multiplied by the gammon/backgammon points. The final points influence the participating players' ratings according to the rating formula. So the Combined Score is the difference between the total points in the games you've won against that player less the total points in the games that player has won against you.
