(from the introduction:) "1775: Invasion of Canada is a two-player game covering the American invasion of Canada which occurred from September 1775 to February 1776." The game lasts six turns. Pieces are units, leaders and supply. In a turn Americans move and then have combat, then the British. Both sides then roll for reinforcements and events, the latter represented by supply. ZOCs inhibit enemy movement, must move into an enemy hex for combat. Combat is by differential CRT, modifiers come from leaders and supply. If all enemy units are not destroyed, victory is determined by control of cities on the map.
