What is Dupery: A Game of Solo Deduction?

This single-player deduction roguelite casts you as a detective pursuing a criminal syndicate in a noir city. You compare statements from characters on procedurally generated grids, annotate a detective board, and make arrests. You progress through regional campaigns in runs, choosing roles and modifiers between cases; wrongful arrests reduce your reputation and can get you fired.

For you if...

+you want social deduction without organizing a multiplayer group
+you enjoy learning complex interactions between character roles

Not for you if...

−you prefer relaxed puzzles over careful, sustained analysis
−you dislike restarting runs after mistakes
