バックギャモン — ルール

Nackgammon

The rules of Nackgammon are the same as in Backgammon; only the starting position differs.

Starting position

The starting position and the direction of play for each colour are shown below:

The first move, moving and hitting, bearing off, the doubling cube, scoring (single game, gammon, backgammon) and the Crawford rule are as in Backgammon.

This variant was invented by Nack Ballard to make his students practise positional play.

Source and interpretation: the Nackgammon description on bkgm.com. There it is played with the Jacoby rule; here the rule is off and cannot be switched on in a challenge.
