This is a different kind of Siege Game, with a large board showing a fortress marked with various combinations of two dice. The attacker rolls dice to eliminate parts of the defence. The defender does the same trying to eliminate the attacking artillery pieces.

Mechanism

Dice Rolling

Rules

Players roll alternately. They put markers on target spaces that match their die rolls (e.g. 1-6 or 5-5). A roll with no matching open combinations misses. The attacker must hit a larger number of spaces to defeat the fortress, but the defender misses more often, with some combinations useless from the beginning.
