- Combining deduction and deck-building with over 100 character cards and various modes
- With approximately 230,000 wishlists… A mystery card game that ranked in the top 250 popular games on Steam
Indie game publisher Offbrand Games, in collaboration with developer UmiArt, will officially launch the single-player social reasoning roguelike card game ‘Demon Bluff’ on the global PC game platform Steam in November 2026. The exact release date will be announced later.
The news of this launch was first revealed at the ‘Convergence Games Showcase.’ Along with the announcement, Offbrand Games captured the attention of global gamers by unveiling a new trailer video offering a glimpse into actual gameplay.
Armed with an unusual combination of genres and unique gameplay, ‘Demon Bluff’ has opened a store page on Steam ahead of its official launch and is continuing preparations to welcome global users.
A village where every card can lie
‘Demon Bluff’ is a new title that combines the ‘single-player deck-building roguelike’ genre with the tension of ‘social deduction’ found in games like Mafia, adding the fun of replayability. Players must investigate a corrupted village and collect clues by meeting various characters (cards) depicted in 2D card art.
The core of the game is to see through the demons and their minions disguised as villagers who are trying to deceive the player with lies, and to join forces with the real villagers to find and eliminate all the hidden demons. It delivers the high tension characteristic of roguelikes, where the game ends the moment you fail to deduce and make a wrong judgment.
A roguelike structure for deck building, offering various modes
The game combines the tension of social reasoning with a roguelike deck-building structure. In basic mode, you save several villages in sequence using a randomly generated deck.
In Deck Building Mode, you can build your own deck and then embark on step-by-step challenges featuring more complex cards, upgrades, and lies. Endless Mode and Challenge Mode are also available.
Saving a village unlocks new character cards that are added to your deck and random encounters. You can also collect card skins, card backs, and decorative items to customize your character. The developers highlighted over 100 unique character cards, various customization options, and increasingly complex mechanics and challenges as key features.
