Backgammon tournaments are formal competitions in which the paired entrants compete to eliminate their pre-assigned opponents. The competitors play a series of games until one player exceeded the predetermined points which constitute the match length.

Points are awarded for single game wins, gammons (double points), backgammons (triple points) multiplied by the value of the doubling cube. After each round the total number of players remaining is halved, until just two players remain in the final round that determines the winner of the tournament.

A major difference between tournament backgammon, head-to-head and chouette is the absence of the Jacoby rule - gammons/backgammon do not count unless the cube has been turned. Instead, the Crawford rule (applicable only to tournaments) specifies that when one player has first reached match-point score (one point short of the winning match-length total) the doubling cube cannot be used for the following game - known as the Crawford game.

The Crawford rule only applies to this one game. If the match has not been decided following the Crawford game, the option to use the cube is returned for all subsequent games, until one player emerges victorious from the match. ..you can find more about backgammon at 247-backgammon.com.
