Dupery: A Game of Solo Deduction

Dupery is a solo deduction game where you play a detective in a noir city, hunting members of a powerful criminal syndicate by solving procedurally generated cases full of lies and deception.

Gameplay

You solve cases by interrogating roles on a grid, cross-referencing their clues and stories to identify liars. Using an in-game detective board with strings and pins, you compile information to deduce who the criminals are before making arrests. Your reputation is key; correct arrests increase it, while wrongfully detaining innocents will get you fired. Between cases, you select new roles, quirks, and modifiers to shape your campaign run.

Story

As a lone detective, you must dismantle a vast criminal network that has infiltrated a noir-inspired city. Your investigation spans three distinct regions, each controlled by a syndicate lieutenant you must uncover and confront. Your journey culminates in a final, brutal showdown with the mastermind behind the entire organization.
