What is Head-to-Head aka Money Game?
Outside the context of a formal tournament, backgammon can be played as a contest between two players (head-to-head) or between multiple players (chouette). In these types of play there is no specific upper-limit to the amount of points which can be won or lost in each game or over a series of consecutive games (a game session). The ultimate number of points won or lost will be dependent upon the value of the doubling cube at the end of the game multiplied by the type of win – eg single game – one point, gammon – two points, backgammon – 3 points. In all the above forms of money games the Jacoby Rule should be assumed to be applicable unless the players agree otherwise at the start of play. The Jacoby Rule (named after the late great gamesman Oswald Jacoby) states that the points awarded for a gammon or backgammon are only awarded if the doubling cube has been turned during the game.
