Not Yet Lost: The Defense of the Polish Post Office in Danzig

Not Yet Lost (NYL) is a quick playing solitaire print-and-play game depicting the heroic defense of the Polish Post Office in Danzing during the German invasion in September, 1939. Using a chit-pull system, the player defends against increasing numbers of German attackers over the course of 15 turns. The player's success is measured by the length of time (in turns) that the Germans are repulsed. With each fighting turn that the defenders survive, Poland is not yet lost.
