Use and Care Manual

3. The Jacoby Rule. Gammons and backgammons count only as a single
game if neither player has offered a double during the course of the
game. This rule speeds up play by eliminating situations where a player
avoids doubling so he can play on for a gammon.
Irregularities
1. The dice must be rolled together and land flat on the surface of the right-
hand section of the board. The player must reroll both dice if a die lands
outside the right-hand board, or lands on a checker, or does not land flat.
2. A turn is completed when the player picks up his dice. If the play is
incomplete or otherwise illegal, the opponent has the option of accepting
the play as made or of requiring the player to make a legal play. A play is
deemed to have been accepted as made when the opponent rolls his dice
or offers a double to start his own turn.
3. If a player rolls before his opponent has completed his turn by picking up
the dice, the player's roll is voided. This rule is generally waived any
time a play is forced or when there is no further contact between the
opposing forces.
