What is French backgammon?
Despite the name, French backgammon bears no resemblance to trictrac. All checkers start off the board and players move in opposite directions around the board, like this: When you roll doubles, the numbers on the top of the dice are played twice each (as in backgammon), then the numbers on the bottom of the dice are played twice each. Then the player who rolled doubles gets to roll again. See full rules here.
