Match score and the Crawford rule

A match is played to a number of points, such as 5 or 7. Each game won scores what it is worth: the cube's value, twice that for a gammon and three times for a backgammon. The first player to reach the match length wins the match.

The Crawford rule

When one player is one point away from winning the match, the next game is the Crawford game: nobody may double in it. After it, the cube is back in play. Choue applies the rule by itself; the score shows CR during the Crawford game.

Unlimited

A match can also be Unlimited (money play): there is no match length, and every game counts for itself. The Jacoby rule can apply then: a gammon or backgammon counts only once the cube has been turned. In a match to a number of points it never applies.

Ending early

You cannot leave a running match. To end it early, resign the match (see Resign, suspend, or leave a game), or suspend it with your opponent to finish later.
