The game recreates the events surrounding Germany's invasion of Netherlands, Belgium and France during World War II (1939-1940). It simulates military operations on a strategic level.

In Jay Selover’s review for Computer Gaming World in 1983, he praised both Fall Gelb and Grey Seas, Grey Skies. He noted that these games were well-researched simulations designed to appeal to board game enthusiasts who now had access to computers as an additional tool for strategy gaming.

Fall Gelb is a turn-based simulation where players command forces on the strategic level of operations. The focus lies in managing resources, troop movements and battles across multiple fronts.

"Both games are excellent simulations with solid data bases... They cater to board gamers who want to leverage computer's capabilities for rule adjudication."The original names:- Grey Seas, Grey Skies- Fall Gelb: The Fall of FranceNote that the game title "Fall Gelb", which is a historical codename used by German military planners in 1940 (Operation Sea Lion), was not translated.
