D-DAY portrays the Allied landings in France and the resulting drive to the Rhine. Play takes the form of 50 game turns, each representing one week of real time, during which the Allies must establish a beachhead, breakout, organize a Patton-like dash across France, and sustain 10 divisions across the Rhine in the face of heavy German opposition.
This was the first wargame to feature a hexagonal grid.
The mapboard and rules were revised in 1965 by Larry Pinsky and the rules were again revised in 1977 by Jim Stahler. The box and counters have remained constant. D-DAY was the first of the "classic" games which remains popular in postal circles to this day (1980), although the 1977 edition rules are a vast improvement and have breathed life into a game which was previously fast becoming forgotten.
The image illustrated is not the cover of the first edition; this featured a drawing of several officers gathered around a map table.
