Saints and Sinners: The Gallery of Polish Kings is a two-player card game in which the players impersonate the powers of good and evil struggling for the souls of Polish monarchs. The aim of the game is to make three characters either "saint" or "damned" by means of playing sin and virtue cards, which are specific for each faction. The game includes sixteen double-sided monarch cards — twelve of them are always in play — that possess different special abilities depending on whether the card has the good or evil side up, and multiple copies of seven deadly sins and seven heavenly virtues cards. The artwork is inspired by a series of paintings by Jan Matejko, a famous Polish painter, under the name "The Gallery of Polish Kings and Dukes" (created 1890–1892).
