How to Play
Uncover the corruption in four steps
A single-player social deduction puzzle solved through logic alone.
-
Read
Each official makes a statement. Some tell the truth. Some don't. Read carefully.
-
Deduce
Cross-reference statements against each other. If two claims contradict, someone is lying.
-
Investigate
Use abilities and hired professionals to test your theory. Mark suspects with stamps and ribbons.
-
Arrest
Find every corrupt official. Three wrong arrests and you lose. Arrest the Mayor by mistake and it's over instantly.
The Chamber
15 unique roles. Each with a statement, an agenda and something to hide.
Every role speaks. Not every role tells the truth.
The Suspects
Legal Advocate
Points at someone and asks: are you lying? One question. One answer. Use it wisely.
Council Chair
Knows whether the corrupt are sitting together or scattered. A single yes-or-no that changes everything.
Police Chief
Feels the tension next door. Tells you if corruption is sitting right beside them.
...and 6 more innocent roles to discover in-game.
The Corrupt
Hidden Among the Chamber
Corrupt officials disguise themselves as innocent roles. Some blackmail, some silence, some convert loyalties. Every lie is a clue if you know where to look.

Werewolf, Mafia, Among Us, Town of Salem, Feign, Blood on the Clocktower. Social deduction has always been about reading people. A group sits in a circle, someone is lying and everyone argues about who.
We wanted to ask a different question: what if you could strip all of that away and leave only the logic?
Rotten Chamber is what happened. A solo social deduction puzzle game where every statement follows rules, every lie leaves a trace and every puzzle has exactly one solution. No dice. No chance. No other players needed.

Frequently Asked Questions
Common questions about this social deduction puzzle game
What is a social deduction game?
A social deduction game is a genre where players must figure out who among them is lying or hiding their true role. Traditionally multiplayer, Rotten Chamber reimagines this as a single-player logic puzzle where you analyze statements and cross-reference clues to identify the corrupt.
Can you play social deduction games alone?
Yes. Rotten Chamber is a solo social deduction game designed from the ground up for a single player. Instead of reading other players, you read role-based statements and use pure logic to deduce who is corrupt.
What makes Rotten Chamber different from other social deduction games?
Most social deduction games like Werewolf, Mafia or Among Us require a group. Rotten Chamber removes the social element and replaces it with a logic puzzle: every statement follows deterministic rules, every level is solvable through deduction alone and there is no randomness in the outcome.
How does the logic puzzle gameplay work?
Each official around a circular table makes a statement based on their role. Innocent officials tell the truth while corrupt officials lie. You cross-reference these statements, use active abilities to test your theories and arrest those you believe are corrupt. Three wrong arrests and you lose.
Is Rotten Chamber a multiplayer game?
No. Rotten Chamber is purely single-player. The game features 45 campaign levels across three acts, custom game modes and an interactive tutorial, all designed for solo play.
Is Rotten Chamber available on Steam?
