Backgammon is a dice and board game where the objective is to get your pieces to the opposite side of the board before your opponent.
When he is not hunting, Baron Dumas has a well defined schedule. Mondays are reserved for golf. Tuesdays and Thursdays are reserved for skeet shooting. Wednesdays for fishing and Friday afternoons for backgammon. Friday mornings between 11:00 and 11:15 are reserved for business matters.
