01One direction, different plans
In long backgammon, also called Narde, both players move in the same direction. There is no hitting: a point occupied by an opponent is blocked. All fifteen checkers start on the head; normally only one checker may leave the head per turn.
02The head and opening doubles
On your first turn, doubles of 3–3, 4–4 or 6–6 allow two checkers to leave the head. Otherwise, only one checker may leave the head per turn. Doubles provide four moves but do not remove other restrictions.
03Blocks, the home board and bearing off
A six-point block may not trap every opposing checker: at least one opposing checker must be beyond the block in the direction of travel. Once all your checkers are home, you may bear them off. A single win scores one point and a gammon two. NARDIKA also includes a doubling cube for long backgammon.
