Dive into history and heroism with Crusaders: The Siege of Acre 1291, a Tactical level Solitaire-Only board-wargame that immerses you and lets you experience the last stand of the Knights Templar and the Crusaders in the Holy Land. Relive the courageous stand of some 15,000 Crusader soldiers, Knights Templars, Teutonic Knights, and Hospitallers as they defend Acre, the critical port city in the Holy Land, against a massive Mamluk army of some 80,000 soldiers armed with siege engines and catapults during the Ninth Crusade.

Crusaders is a dice rolling, tower defense, solitaire game. Players take the role of Crusaders and try to defend Acre from the Mamluk attackers. Players win or lose depending on if the walls are breached and enough defenders survive.
