Kards

Kards is a free-to-play collectible World War II card game from developer 1939 Games. Build decks based around any of the major powers in the war and challenge other players or AI. Decks are built of cards featuring aircraft, tanks, artillery, and infantry, as well as other assets from all theaters of the war.

Described as “easy to learn, but hard to master”, Kards’ plays include “Blitzkrieg tactics” such as strategically bombing the enemy or digging in for better defense. During their turn, players will give orders, commit espionage, sabotage the enemy, develop advanced technology, and call in naval support.

Kards is a completely free-to-play game with regular updates that add new gameplay features. All features are accessible from the start with no paywall lockout.
