Based and set in 18th century France, the game follows a mute peasant who assists Comte de Saint Germain to con gamblers from various parlors as they pursue a Royal rumor called "The Twelve Bottles of Milk".

The player takes on the role of a mute boy serving in a tavern in south France,[1] where he is then recruited by the Comte de Saint Germain to help participate in the swindling of their opponents riches and secrets.

[4] Card Shark is developed by Nerial, the same studio that created Reigns which is a strategy video game set in a fictional medieval world.

Nerial collaborated with artist Nicolai Troshinsky to bring the gameplay and artwork of Card Shark to fruition, which would be published by Devolver Digital.
