The Devil's Due offers a unique blend of poker mechanics and strategy gameplay on Windows. Players engage in one-on-one battles against a variety of demonic monsters, each equipped with special abilities, where the strength of their poker hand directly influences damage dealt. The game introduces a fascinating twist where players can utilize an array of cheat tricks, such as concealing or swapping cards during battles, boosting card values, and sabotaging opponents. However, using these tricks raises the suspicion meter of foes, introducing an element of risk to the gameplay.

As players progress, they experience a roguelike system where each death provides opportunities for permanent upgrades, new cheat cards, and powerful relics. The game features tarot cards at the beginning of each level, which dictate the player's journey through various encounters, shops, and challenges. This strategic element encourages players to adapt their decks and cheat strategies to navigate the depths of Hell and strive for redemption.
