Kards is a free to play World War II themed online digital collectible card game developed and published by 1939 Games. It was released in early access on Steam on April 12, 2019, and was fully released on April 15, 2020. Mobile ports  with crossplay capabilities between platforms have been released for both iOS and Android on June 6, 2023.

Gameplay 
Kards is a turned-based collectible card game. It is played between two players, each with a deck of 40 cards themed around strategies of powers during World War II: Germany, Great Britain, Poland, the United States and Imperial Japan. For example, a German deck relies on Infantry to overwhelm the opponent with tanks. The objective is to destroy the enemy's headquarters represented by a card on the board.

The playing field, called "battlefield" in-game, is divided into three fronts, the player's support line, front line, and the enemy's support line. The support and front line can hold up to four and five cards respectively, but units must be deployed in the player's support line when played. In order to play cards, players expend a resource called 'Kredit;' that refreshes every turn, after which the maximum Kredit increases by one, up to 12 after which ramp cards must be played to get to the maximum of 16. Kredits can also be used to move military units to the front line or to attack enemy units. Once a unit has been moved to the front line, they cannot retreat back unless forced to by certain cards that specify otherwise. The front line can only be controlled by one player at a time, as such, whoever controls it has a strategic advantage on the battlefield.

Game modes 
Rust offers players the opportunity to compete against a computer AI or human opponents online through a tiered-ranking system. At the end of each one-month-long season, players' ranks reset, allowing for fresh competition and new opportunities to climb the ladder. Alternatively, players can engage in draft matches against other human players, where they must build a deck from scratch by choosing one card out of three randomly presented options at a time until they have a complete deck. They will then use this deck to compete, aiming to win seven games or avoid losing three games. Rewards in the draft mode are based on players' performance.

Moreover, Kards offers five single-player campaigns that allow players to immerse themselves in themed military campaigns from the war. These campaigns provide a narrative-driven experience where players can progress through various missions, experiencing key moments and battles from World War II.

Game modes include skirmish, ranked play, unranked play, draft mode, and single-player campaigns.

Development and release 
1939 Days was founded in 2015 by former CEO Ívar Kristjánsson and Project Lead Guðmundur Kristjánsson of CCP Games, best known for developing Eve Online, with Kards being their first project.

At first, Kards started out as a cardboard prototype using real life cards and went into full production as an online CCG after receiving a $70,000 grant, making its first public appearance in March 2019.

Over the course of its development, Kards received $100 million in endowments from venture funds, including the Chinese investing company Supercell, to support future updates and a mobile version of the game.

Card artwork was sourced and licensed from World War II enlistment posters, propaganda art, and toy box art from the 1970s and 1980s, including box art of Airfix scale model kits famously painted by Roy Cross. Artwork is also commissioned from private artists as a last resort. Most of the commissioned art comes from David Pentland and Jarosław Wróbel.

The game released on April 15, 2020, on PC with continued post-launch support in the form of expansions, timed-limited events, and hotfixes.
